2017 Honda Civic Headlights: Everything You Need to Know About Design, Performance, Maintenance, and Upgrades

The 2017 Honda Civic, a standout in the compact car segment, is celebrated for its balance of style, efficiency, and practicality. Among its often-overlooked but critical features are the headlights—an element that impacts not just aesthetics but nighttime visibility, safety, and overall driving experience. Whether you own a 2017 Civic or are considering one, understanding the design, performance, common issues, and upgrade options for its headlights will help you maintain tip-top shape or make informed decisions. This guide dives deep into every aspect of the 2017 Honda Civic headlights, combining technical details with real-world insights to empower you with actionable knowledge.

Design: A Blend of Form and Function

The 2017 Honda Civic’s headlights were redesigned as part of the tenth-generation model’s overhaul, prioritizing a modern, aggressive look while optimizing aerodynamics and light output. Here’s a breakdown of their design elements:

Exterior Styling

All 2017 Civic trims feature projector-beam headlight assemblies as standard, a step up from the reflector-style units on older models. The headlight clusters are integrated into the front fascia, with sharp, angular lines that align with the Civic’s sporty silhouette. LED daytime running lights (DRLs) are standard across all trims, positioned above the main headlight housing. These DRLs use a thin, horizontal LED strip that glows amber in some markets (depending on regulations) and white in others, adding a signature look to the front end.

Higher trims, such as the EX, EX-L, and Touring, receive upgraded LED headlights instead of halogen bulbs. The Touring trim takes it further with an adaptive front-lighting system (AFS), which adjusts headlight direction based on steering input—helping illuminate curves at night. This feature is absent in lower trims like the LX, which stick to static LED or halogen setups depending on market.

Internal Components

Beneath the sleek exterior, the 2017 Civic’s headlights use a combination of reflectors and projectors. Projector lenses focus light into a tighter, more focused beam, reducing glare for oncoming drivers—a key safety feature. Halogen-equipped models use a halogen bulb (typically a 9005 or 9006 type) paired with a silver-colored reflector bowl, while LED models integrate LED chips into the projector assembly for a cleaner, more uniform light output.

Notably, the headlight housings are made of durable polycarbonate plastic, treated with a UV-resistant coating to prevent yellowing over time. However, this coating can degrade with prolonged sun exposure, a common issue we’ll address later.

Performance: How Well Do They Actually Light the Road?

Visibility is non-negotiable for nighttime driving, and the 2017 Civic’s headlights deliver mixed results depending on trim and conditions.

Standard Halogen Headlights (LX Trim)

Base LX models come with halogen bulbs producing around 1,200 lumens per bulb. On paper, this meets minimum legal requirements, but real-world performance is underwhelming. In urban areas with street lighting, they get the job done—but on unlit rural roads, the beam pattern is narrow and short, requiring drivers to rely more on high beams. High beams improve reach to about 250 feet, but the lack of cutoff shielding can cause glare for oncoming traffic if not aimed properly.

LED Headlights (EX, EX-L, Touring Trims)

Upgraded LED headlights in higher trims are a noticeable improvement. With an output of roughly 2,000 lumens per bulb, they produce a brighter, whiter light (5,000K color temperature) that cuts through darkness more effectively. The projector lenses focus the beam into a distinct horizontal cutoff, minimizing glare. On unlit roads, LED low beams illuminate up to 300 feet, and high beams extend to over 400 feet—comparable to premium compact cars in the same class.

The Touring trim’s adaptive headlights (AFS) add another layer of utility. As you turn the steering wheel, the headlights pivot up to 15 degrees, illuminating the inside of curves. This is especially useful on winding roads, where traditional fixed headlights leave dark spots.

Comparison to Competitors

Compared to rivals like the 2017 Toyota Corolla or Mazda3, the Civic’s LED headlights (in higher trims) outperform the Corolla’s standard halogens but lag slightly behind the Mazda3’s optional LED setup, which offers a wider spread and better peripheral illumination. Still, the Civic’s headlights are competitive for their class and price point.

Common Issues and How to Address Them

While the 2017 Civic’s headlights are generally reliable, owners often report two main problems over time: yellowing/oxidation of the housing and reduced light output from aging bulbs.

1. Headlight Housing Yellowing

The polycarbonate plastic used in the headlight housings is prone to UV damage. Over 3–5 years of sun exposure, the UV-resistant coating wears off, causing the plastic to oxidize and turn yellow. This not only makes the car look older but also reduces light output by scattering and blocking beams—effectively dimming the headlights even if the bulbs are new.

Solution:

• Cleaning and Polishing: For mild yellowing, use a headlight restoration kit (available at auto parts stores). These kits typically include sandpaper (1,000–3,000 grit), a polishing compound, and a UV protectant sealant. Follow the instructions carefully: wet sand to smooth the surface, polish to remove oxidation, then apply the sealant to restore clarity and block future UV rays.
• Replacement: Severe yellowing or cracks may require replacing the entire headlight assembly. OEM (Honda) replacements cost $300–$500 per side, while aftermarket options (from brands like GTR Lighting or DEPO) are cheaper ($150–$300) but vary in quality.

2. Dimming or Flickering Bulbs

Halogen bulbs in base models can dim over time due to filament wear. LED bulbs in higher trims are more durable but may flicker if the wiring is loose or if the bulb isn’t properly seated.

Solution:

• Halogen Bulbs: Replace every 4–6 years or when brightness drops. Use OEM or high-quality aftermarket bulbs (e.g., Sylvania SilverStar Ultra) to ensure consistent output. Avoid cheap no-name bulbs—they often have shorter lifespans and inconsistent color temperature.
• LED Bulbs: Check for loose connections in the headlight housing. If flickering persists, the bulb may be faulty; replace it with a compatible LED unit (more on upgrades below).

Upgrading Your 2017 Civic Headlights: Options and Considerations

If your Civic’s headlights feel inadequate—whether due to age, trim limitations, or a desire for better performance—upgrading is a viable solution. Here are your options:

1. OEM Upgrades

Honda offers factory upgrades for some trims. For example, you can replace halogen bulbs in the LX trim with LED units designed for higher trims. Note that this may require reprogramming the car’s computer to adjust the headlight control module, as LED bulbs draw less power than halogens.

2. Aftermarket Bulbs

For a budget-friendly upgrade, swap halogen bulbs for LED or HID (xenon) options.

• LED Bulbs: Brands like Philips Ultinon, Diode Dynamics, and Morimoto offer plug-and-play LED bulbs (e.g., Philips D2R LED) that fit the 2017 Civic’s halogen sockets. These produce 3,000–5,000 lumens per bulb, doubling the output of stock halogens. Ensure the bulb has a fan or heat sink to prevent overheating—cheap LEDs without cooling systems fail prematurely.
• HID Kits: High-intensity discharge (HID) bulbs (e.g., Sylvania Cool Blue Intense) emit a bluish-white light (4,300K–6,000K) and offer even brighter output (up to 3,500 lumens). However, HID conversion kits require ballasts and may not be street-legal in all areas—check local regulations first.

3. Full Headlight Assembly Replacement

For the best results, replace the entire headlight assembly with an aftermarket or OEM upgraded unit. Aftermarket options from companies like Morimoto or Diode Dynamics include projector lenses, LED projectors, and even adaptive lighting features similar to the Touring trim. These assemblies often come pre-aimed and with a lifetime warranty, ensuring durability and proper fit.

Key Considerations When Upgrading

• Legality: Modified headlights must meet DOT (U.S.) or equivalent standards. Avoid blue-tinted bulbs or unshielded LEDs/HIDs that create excessive glare—these are illegal and dangerous.
• Aiming: After installation, have the headlights professionally aimed. Misaligned beams can blind other drivers or reduce your own visibility.
• Cost vs. Benefit: A basic LED bulb upgrade costs $50–$100 per side. A full aftermarket assembly runs $300–$800 per side but delivers superior performance and aesthetics.

Maintenance Tips for Long-Lasting Headlights

To keep your 2017 Civic’s headlights performing optimally:

• Clean Regularly: Use a mild soap and water solution to remove dirt, bugs, and road grime. Avoid abrasive cleaners that scratch the housing.
• Inspect Annually: Check for cracks, yellowing, or loose bulbs. Catching issues early prevents bigger problems.
• Protect from Debris: Park in garages when possible to minimize sun and stone damage.

Final Thoughts

The 2017 Honda Civic’s headlights are a strong point for higher trims, offering bright, stylish LED lighting with advanced features like adaptive aiming. Base models with halogens are functional but benefit greatly from upgrades. By understanding their design, performance, common issues, and upgrade paths, you can ensure your Civic’s headlights remain a safety asset and a source of pride. Whether you’re maintaining stock units or upgrading to aftermarket solutions, prioritizing quality and proper installation will pay off in better visibility and longer component life.
