TIME FOR AN UPGRADE: This halo kit, designed specifically for the 2014-2021 Toyota Tundra, includes custom-sized "C" light accents with multiple functions that will add a distinct, unique look to your vehicle both day and night!

HIGH OUTPUT, CLEAN APPEARANCE: 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.

PURE WHITE COLOR, ASSEMBLED 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!

CONSTANT-CURRENT POWER: 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!

NOTE: When installed on STANDARD headlamps (no factory LED): this LED will illuminate a brilliant amber as DRL, extremely bright white when headlamps are turned on, and flash amber when the turn signal is engaged. When installed on PREMIUM headlamps (with factory LED): this LED will illuminate bright white as DRL, dimmed white when headlamps are turned on, and flash a brilliant amber when the turn signal is engaged.
