Choosing WRX LED Headlights: Bulbs vs. Housings & Fitment

Upgrade your Subaru WRX's lighting the right way — LED bulb swaps vs. full housing assemblies, beam pattern, color temperature, and what actually fits by generation.

By WRX Parts Team Updated July 22, 2026

Factory halogen or aging projector headlights on an older WRX can feel dim and yellow, and hazy housings make it worse. LED upgrades are one of the highest-impact, lowest-cost improvements you can make — if you buy the right kind. This guide covers the two paths and points you to new parts on Amazon and used/OEM lighting on eBay Motors.

Two ways to go LED

  • LED bulb swap: you replace the halogen bulbs with LED bulbs in your existing housings. Cheapest and quickest, but only worth it if the bulb is engineered for your housing type and your housings are still clear.
  • Full LED housing assembly: you replace the entire headlight unit with one built for LED output and beam pattern. More expensive, but it fixes hazy housings and delivers a clean, correct beam — and on many WRX generations the aftermarket “sequential” LED assemblies are a big visual upgrade.

If your housings are yellowed or foggy, a full assembly almost always looks and performs better than a bulb swap.

What actually matters

  • Beam pattern and cutoff. This is everything. A good upgrade lights up the road without blinding oncoming traffic. A bad one scatters glare and gives you less usable light.
  • Color temperature. Aim for ~5000–6000K pure white. Skip the blue-tinted “style” bulbs — they perform worse in weather.
  • Fitment. Confirm the part matches your exact WRX generation (GD, GR, VA, VB) and trim — connectors and housing shapes differ across years.
  • Aim. Always re-aim after any lighting change.

How to buy

  • New LED bulbs and full assemblies: Amazon Automotive — browse the lighting category.
  • Used or OEM housings and factory assemblies: eBay Motors, via the search buttons above.

Pair your headlight upgrade with matching LED fog lights and you’ll have a WRX that sees — and is seen — far better than it did from the factory.

Frequently Asked Questions

Can I just drop LED bulbs into my factory WRX headlights?
Sometimes. A quality LED bulb designed for a projector or reflector housing can work well, but a poorly matched bulb creates glare and a bad beam pattern that blinds oncoming drivers and actually reduces your usable light. If your factory housings are old and hazy, a full LED assembly designed for the beam pattern is often the better upgrade.
What color temperature is best for headlights?
Around 5000–6000K (bright white) offers the best real-world visibility for most drivers. Higher 'blue' color temperatures look flashy but scatter more in rain and fog and give you less usable light. Stick near pure white for the best combination of looks and function.
Are LED headlight upgrades legal?
It varies by region, and enforcement targets glare and beam pattern more than the bulb type itself. A properly aimed assembly with a correct cutoff is far less likely to be an issue than a cheap bulb that throws light everywhere. Always aim your headlights after any lighting change.
