Diode Dynamics Switchback LED C-light DRLs for Headlights Subaru WRX / STI 2015-2021

Time to upgrade your WRX or STi headlamps! These C-Light LED modules are circuit boards that fit right behind the factory diffusing reflector, illuminating in an extremely bright white, as well as a brilliant amber. Don't be fooled by other options on the market: these modules have been designed from the ground-up, and manufactured in St. Louis, Missouri, to be absolutely the brightest lights physically possible. They are compatible with all factory headlamps: WRX Base/Premium as well as WRX Limited and STi.

The custom-designed LED modules replace the factory bulb or single LED, illuminating with a much higher intensity. With our proprietary high-density "HDLED" technology, these modules are populated with over 500 LED chips, which are then coated by a diffusing gel, resulting in a perfectly uniform light when turned on. When it's off, the diffusing gel hides the chips, resulting in a clean, OEM appearance.

Manufactured in USA, the modules light in a pure 6000K white color, not a cool blue like cheaper products on the market. And because they use modern high-power amber chips, rather than traditional LEDs, the amber is even brighter than the white!

To power the modules efficiently, your order includes two custom-designed drivers, which feature transient voltage suppression, reverse protection, and a switching driver for extremely high reliability over time. And here's what really makes this product shine over the competition: with an embedded microcontroller, the drivers utilize multi-stage PWM dimming, to allow for a half-brightness white, for use at night (parking lights), as well as a full-power white, for use as DRL during the day. Finally, the amber is run at even higher power, making the turn signal easily visible in broad daylight!

SPECIFICATIONS

Total LEDs: 524 (262 per side)
Real LED Output Power: 13 watts Amber, 10 watts DRL, 5 watts parking (per side)
Inputs: Plug-and-play connector for ground and parking light. T-taps for DRL and turn signal.
Integrated Protection: Full waterproofing and shockproofing, transient suppression, overvoltage protection, thermal shutdown, reverse input protection.

Wiring instructions are included with your order. Using the included connectors, you will plug in the parking light connector, then tap turn signal and DRL signals, if you desire. We hope to release a plug-and-play wiring option in the next few weeks, which will be compatible with existing modules. You do not need to use resistors or a new flasher module with this product.

Professional installation is recommended, as the headlights must be opened. However, these lamps are substantially easier than most to work with, so we do recommend watching the installation process yourself, by viewing their video (to be released soon).

All Diode Dynamics products are backed by a 3-year replacement warranty.

NOTE:

If you do not have spare butyl sealant in hand, RetroRubber or other butyl sealant is REQUIRED. The OEM sealant cannot be reused! TRS RetroRubber can be stretched to the proper length and width to fit the headlight casing channel.
