1. Understanding the 2015 Chrysler 200 Headlight System: Key Components and Design

Before diving into repairs, it’s essential to grasp how the 2015 Chrysler 200’s headlights work. The system is designed for both functionality and aesthetics, combining several components to deliver reliable illumination.

a. Headlight Types in the 2015 Chrysler 200

The 2015 Chrysler 200 was available with two primary headlight technologies, depending on the trim level and optional packages:

  • Halogen Bulbs: Standard in base LX trims, halogen bulbs use a tungsten filament heated by an electric current to produce light. They are affordable but less energy-efficient and have a shorter lifespan (typically 500–1,000 hours) compared to newer options.
  • Xenon (HID) Headlights: Optional on Touring and Limited trims, HID headlights use high-voltage electricity to ionize xenon gas, producing a brighter, whiter light with a longer lifespan (2,000–3,000 hours). They require a ballast to regulate voltage, making them more complex than halogens.

Note: The 2015 Chrysler 200 does not come standard with LED headlights; these were introduced in later model years.

b. Core Components

Every headlight assembly on the 2015 Chrysler 200 includes:

  • Bulb/Module: The light source (halogen or HID).
  • Reflector: Shapes and directs light outward.
  • Lens: Protects internal components and diffuses light to reduce glare.
  • Housing: The outer casing that mounts the assembly to the vehicle.
  • Electrical Connector: Links the bulb/module to the car’s wiring harness.
  • Parking Light/Signal Bulb: Integrated into the headlight housing for side visibility.

For owners, recognizing these parts helps identify issues (e.g., a cracked lens vs. a faulty bulb) and streamline repair efforts.

c. How the System Operates

When you turn the headlight switch to “ON” or “AUTO,” the vehicle’s body control module (BCM) sends power to the headlights. In AUTO mode, a photoelectric sensor (located near the rearview mirror) triggers the headlights based on ambient light levels. For HID systems, the BCM also communicates with the ballast to initiate the 25,000-volt arc needed to ignite the xenon gas.

Understanding this flow is key to diagnosing problems—e.g., if the sensor fails, the lights won’t activate automatically; if the ballast malfunctions, HID bulbs won’t light even if they’re new.

2. Common 2015 Chrysler 200 Headlight Problems: Symptoms and Causes

Headlight issues in the 2015 Chrysler 200 often start subtly but can escalate quickly. Here are the most frequent problems owners report, along with their root causes:

a. Headlights Won’t Turn On (Complete Failure)

  • Symptoms: No light at all when the switch is activated; dashboard warning light may flash (if the BCM detects a fault).
  • Common Causes:
    • Burnt-Out Bulb: The most straightforward issue. Halogen bulbs burn out when the tungsten filament breaks; HID bulbs fail if the gas leaks or the electrode erodes.
    • Blown Fuse: The headlight circuit has multiple fuses (check the under-hood fuse box or interior driver’s side panel). A blown fuse stops power from reaching the bulbs.
    • Faulty Electrical Connector: Corrosion, loose pins, or frayed wires in the connector can interrupt power.
    • Bad Ballast (HID Only): The ballast regulates voltage to the HID bulb. If it fails, the bulb won’t ignite.
    • Broken Wire in Harness: Rodents, vibration, or wear can damage wires leading to the headlights.

b. Dimming or Flickering Headlights

  • Symptoms: Lights operate at reduced brightness, or they flicker intermittently (especially at low speeds or when the engine idles).
  • Common Causes:
    • Loose Ground Connection: The headlight system relies on a “ground” wire to complete the electrical circuit. A loose or corroded ground (often near the headlight housing or engine block) causes intermittent power loss.
    • Worn-Out Bulb: As halogen bulbs age, the tungsten filament thins, reducing light output. Flickering may occur as the filament weakens.
    • Failing Alternator: A weak alternator doesn’t charge the battery properly, leading to low voltage. Dimming headlights are an early warning sign of alternator issues.
    • Voltage Regulator Malfunction: The voltage regulator ensures consistent power to electrical components. If it fails, voltage spikes or drops can affect headlights.

c. Uneven or Scattered Light (Poor Beam Pattern)

  • Symptoms: One headlight illuminates less area than the other; light spills upward (glare) or downward (reducing forward visibility).
  • Common Causes:
    • Misaligned Headlights: Over time, vibration or impacts (e.g., potholes) can knock the headlight housing out of alignment.
    • Dirty or Opaque Lens: Road grime, bugs, or oxidation on the lens scatters light. A cracked lens may also allow moisture inside, creating a foggy effect.
    • Worn Reflector: The reflector’s mirrored surface can degrade, misdirecting light.

d. Automatic Headlights Not Activating (AUTO Mode Failure)

  • Symptoms: Headlights stay off in low light (e.g., at dusk or in a parking garage) even when the switch is set to “AUTO.”
  • Common Causes:
    • Faulty Photoelectric Sensor: The sensor, located on the windshield near the rearview mirror, may be covered in dirt, bugs, or film, preventing it from detecting light levels.
    • BCM Software Glitch: Rare, but the body control module may need a reset or reprogramming if it misinterprets sensor data.
    • Blown Fuse for AUTO Function: Some models have a separate fuse for the automatic headlight system.

3. Step-by-Step: Maintaining Your 2015 Chrysler 200 Headlights to Extend Lifespan

Preventive maintenance is the best way to avoid costly repairs. Here’s how to keep your 2015 Chrysler 200’s headlights in top condition:

a. Regular Cleaning: Preventing Dimming and Damage

  • Frequency: Clean headlights every 2–3 months, or more often if you drive on salted roads or in dusty areas.
  • Tools Needed: Microfiber cloth, non-abrasive headlight cleaner (avoid household cleaners with ammonia, which can damage plastic), and a soft-bristle brush (for hard-to-reach grime).
  • Process:
    1. Rinse the headlights with water to remove loose dirt.
    2. Apply a small amount of headlight cleaner to the cloth (not directly on the lens) and rub in a circular motion to lift grime.
    3. For oxidized or yellowed lenses (common in older vehicles), use a headlight restoration kit (available at auto parts stores). These kits typically include a sanding pad, polish, and sealant to remove surface damage and add UV protection.
    4. Rinse thoroughly and dry with a microfiber cloth to prevent water spots.

Pro Tip: Avoid using high-pressure washers directly on the headlights—the force can crack the lens or force water into the housing.

b. Inspecting Seals and Gaskets: Preventing Moisture Intrusion

Moisture inside the headlight housing causes fogging, corrosion, and electrical shorts. To check the seals:

  1. Remove the headlight assembly (see Section 4 for removal steps).
  2. Examine the rubber gasket around the perimeter of the housing. Look for cracks, splits, or brittleness.
  3. If the gasket is damaged, replace it immediately. Most auto parts stores sell OEM or aftermarket gaskets specific to the 2015 Chrysler 200.
  4. Apply a thin layer of dielectric grease to the new gasket before reinstalling the housing. This repels water and prevents the gasket from sticking over time.

c. Checking Bulbs and Connections: Catching Issues Early

  • Monthly Visual Check: With the engine off, remove the hood and visually inspect the headlight housings. Look for condensation (a sign of seal failure), corroded terminals, or loose bulbs.
  • Testing Bulbs: If a headlight is dim or out, remove the bulb (see Section 4) and inspect the filament. A broken filament means the bulb needs replacement. For HID bulbs, check for clouding or discoloration in the glass—these are signs of failure.
  • Tightening Connections: Use a small screwdriver to gently wiggle the electrical connector. If it feels loose, unplug it, clean the terminals with electrical contact cleaner, and reinsert it until it clicks securely.

d. Aligning Headlights: Ensuring Proper Beam Pattern

Misaligned headlights are not just a safety hazard—they’re illegal in most states. Here’s how to align them:

  1. Park the vehicle on a flat, level surface 25 feet away from a wall.
  2. Turn on the low beams. Use a piece of tape to mark the vertical and horizontal centerlines of the light pattern on the wall.
  3. Locate the headlight adjustment screws (usually located on the top and side of the housing).
  4. Loosen the screws slightly, then adjust the beam up/down and left/right until the center of the light hits 2–4 inches below the tape line (check your owner’s manual for exact specs).
  5. Tighten the screws and recheck the alignment.

Note: Some 2015 Chrysler 200 trims have automatic leveling headlights. If yours does, ensure the system is calibrated by a dealer or certified technician.

4. Replacing the 2015 Chrysler 200 Headlight: A DIY Guide

If maintenance doesn’t resolve the issue, it’s time to replace the headlight. Here’s a step-by-step guide, whether you’re swapping a halogen bulb or upgrading to an aftermarket assembly.

a. Tools and Materials You’ll Need

  • Replacement headlight bulb (OEM: Sylvania 9005 for halogen; Philips D3S for HID) or pre-assembled headlight unit.
  • Phillips-head screwdriver (for removing trim panels).
  • Socket wrench set (usually 10mm or 12mm for housing bolts).
  • Flashlight (to see into tight spaces).
  • Electrical contact cleaner (optional, for corroded connectors).

b. Removing the Old Headlight

Note: Always disconnect the battery before working on electrical components to avoid short circuits.

  1. Open the Hood: Release the hood latch (front hood release near the driver’s side knee panel, then secondary release at the front of the hood).
  2. Remove the Front Bumper Cover (Partial):
    • Locate the screws holding the bumper cover in place: 3–4 screws along the top edge (near the headlight) and 2–3 screws on each side (under the fender).
    • Use a screwdriver to remove these screws. Gently pry the bumper cover away from the headlight housing using a trim tool (avoid scratching the paint).
  3. Disconnect the Electrical Connector:
    • Locate the headlight’s electrical connector (a large plug attached to the back of the housing).
    • Squeeze the locking tab on the connector and pull it straight off. For stubborn connectors, twist slightly while pulling.
  4. Remove the Headlight Housing Bolts:
    • There are typically 3–4 bolts securing the headlight to the vehicle: 2 at the top (near the radiator support) and 1–2 at the bottom (near the frame).
    • Use a socket wrench to remove these bolts. Keep them in a safe place to avoid loss.
  5. Pull the Headlight Out:
    • Gently tug the headlight housing away from the vehicle. It may be stuck due to dirt or debris—use a trim tool to loosen it if necessary.
    • Once free, set the old headlight aside.

c. Installing the New Headlight

  1. Transfer Components (If Upgrading): If replacing the entire assembly, transfer any necessary parts from the old housing to the new one, such as:
    • Parking light bulbs.
    • Turn signal bulbs.
    • Rubber gaskets (if not pre-installed on the new housing).
  2. Align and Insert the New Headlight:
    • Line up the new headlight with the mounting holes. Use your hand to guide it into place, ensuring the electrical connector faces the driver’s side.
    • Push the housing firmly until it clicks into the mounting slots.
  3. Reinstall Bolts and Screws:
    • Tighten the mounting bolts in a crisscross pattern to avoid warping the housing. Do not overtighten—plastic housing bolts strip easily.
    • Replace the bumper cover screws and tighten them securely.
  4. Reconnect the Electrical Connector:
    • Push the connector back onto the headlight until it clicks. Test the headlights immediately by turning the switch to “ON.”

d. Original vs. Aftermarket Headlights: Which Should You Choose?

  • OEM (Original Equipment Manufacturer): Recommended for most owners. OEM headlights are designed to fit perfectly, match the factory beam pattern, and maintain resale value. They’re available through dealerships or authorized retailers like Mopar.
  • Aftermarket: Cheaper than OEM but varies in quality. Look for aftermarket units certified by SAE (Society of Automotive Engineers) or ECE (Economic Commission for Europe) to ensure they meet safety standards. Avoid no-name brands—they often have poor optics, incorrect beam patterns, or weak housings that crack easily.

Pro Tip: If your 2015 Chrysler 200 has HID headlights, replacing just the bulb is possible, but HID kits (which include a new bulb, ballast, and wiring) are often more reliable than aftermarket bulbs.

5. Troubleshooting Advanced Issues: When to Call a Professional

While many headlight problems can be fixed with basic tools, some require professional diagnosis. Here’s when to seek help:

a. HID Headlight System Failures

HID systems are complex, with components like ballasts, igniters, and sensors that are difficult to test without specialized tools. If you’ve replaced the bulb and ballast but still have no light, a certified mechanic can use a multimeter to check voltage at the ballast and ignition module.

b. Wiring Harness Damage

Rodents, corrosion, or accidents can chew through or corrode the wiring between the headlight and the BCM. A professional can use a wiring diagram to trace the fault and repair or replace damaged wires.

c. BCM Malfunctions

The body control module (BCM) manages headlights, wipers, and other systems. If the BCM is faulty, it may need reprogramming or replacement. This requires a dealer or shop with access to Chrysler’s diagnostic software (WiTech).

d. Legal Compliance

If your headlights are damaged, misaligned, or modified (e.g., aftermarket tinted lenses), they may not meet state safety standards. A professional can ensure replacements comply with local regulations (e.g., minimum brightness, color temperature limits).
