Over 200 cars a month choose OLM for their C-Light bulbs*. This is no surprise as SubiSpeed has tested a wide variety of bulbs to find the best match. Not only did we test bulbs, but they were tested on an actual 2015 WRX.
Boomerang Bulb Characteristics
This C-light has a specific set of requirements which must be met. The housing for the bulb is small. A bulb with excessive heat output will damage the mirror finish in the headlight. We've pushed the limits and found the point in which discoloration begins. The OLM bulbs we offer have exceptional light output with little heat compared to other products on the market.
DRL Harness Compatible
For ways to keep your boomerang lit as a DRL, please take a look at our DRL harness.
OLM's 4th generation t10 light utilizes 4 SMD 3030 chips and has a white housing. Light output is clean and projected 180 degrees from the top of the bulb. This makes it a great candidate for a C-light bulb.
Total chip output is ~250 lumens with a current draw ~160mA.
Vehicle Specific Installation Details:
Does not require load resistors or blinker module.

This Part Fits
2015-2017 Subaru WRX OLM LED Headlight Boomerang Bulbs
It was simple and only took 10 minutes to install! Had a small issue with one of the bulbs but subiespeed took care of me and now it fits perfectly! I’m honestly glad this isn’t a company that rips people off and is actually there to help us!
Improved the look immediately

Would have been easier to install if I was smarter or had smaller hands. Love the look. Your car probably needs this upgrade.
Easy and look great
By JoeJanuary 26, 2018
Installing these bulbs took 2 minutes at most. I have a 2018 Forester XT Premium and these fit exactly the same. Should be labeled to fit the XT premium 2017+2018. If you want your boomerang bulbs to look nice and bright and white, this is the bulb to get. They look great with my led headlights

These are a must if you have a premium or base model and don't want to go for the C light harness. Install was a pice of cake and they look tons better than the factory ones. Be warned! You will automatically want to change out the low beam lights after you change these! That's how good they look.
Better than stock by a thousand
By JesseFebruary 10, 2017
I ordered the circuit series LED set, very bright and give a better output than the stock bulbs. Just need to slide them in. Only problem you could have is figuring out what to reach for after moving the battery/intake box.
By ChristopherJanuary 10, 2017
Even though I had to move the battery and Cobb Big SF intake box out of the way, installation was relatively easy. I didn't notice how yellow the stock bulbs were until I upgraded the low beams and fog lights to OLM LED Alpha. These are a phenomenal value. I highly recommend.
