Description

OLM 4th Gen C-Light Boomerang Bulbs – Clean, Bright, and Built for Your WRX

Say goodbye to the dull amber glow of the factory halogen C-light bulbs. The OLM 4th Generation C-Light Bulbs are specifically designed to bring out the sharp, clean look your 2015+ WRX deserves. Factory boomerang lights on base and premium models use halogen bulbs, which produce a dim, orange hue—and upgrading to HIDs or brighter headlights only makes the mismatch worse.

With over 200 vehicles a month choosing OLM C-light bulbs, it’s clear these are a trusted upgrade. Extensively tested by SubiSpeed for brightness, beam pattern, and long-term durability, these bulbs are tailored to deliver crisp white light without compromising the integrity of your headlights.

Boomerang Bulb Engineering – Precision Fit, Maximum Output

The C-light area is a tight, heat-sensitive space. Excess heat can damage the reflective chrome surface inside the housing. That’s why OLM designed these bulbs with high-efficiency SMD 3030 chips to balance brightness with thermal control. You get vibrant illumination (~250 lumens per bulb) with a minimal heat signature—avoiding damage and discoloration common with inferior products.

These bulbs are also fully compatible with DRL harnesses, allowing you to keep your boomerang lights on during the day for a bold, modern look.

Key Features:

  • Specifically designed for 2015+ WRX Base & Premium headlights

  • Clean, white light replaces factory amber glow

  • Utilizes 4 SMD 3030 chips for wide-angle (180°) light output

  • ~250 lumens per bulb / ~160mA current draw

  • Low heat output protects your headlight housing

  • Compatible with DRL harness (sold separately)

  • No load resistors or blinker modules required

  • Backed by a 1-year manufacturer’s warranty

  • Sold as a pair

What's in the Box:

  • 2x OLM Gen 4 T10 C-Light Bulbs (white)

  • Installation instructions + support resources

Upgrade your WRX’s style and visibility with a trusted, plug-and-play solution designed for long-term performance. The OLM 4th Gen C-Light Boomerang Bulbs deliver the clean, white glow your headlights have been missing.
