Profile Performance: The automotive aftermarket's best name in LED Lighting and when it comes to LED Halos and easily the one that gets our nod of approval. Fact is that while the rest of the industry is busy sticking their name on a generic or standing still with the same-old same-old, Profile is working hand-in-hand with the industry's experts to keep pumping out the products with the performance that we all expect. Their Profile Dual Red Halos are perfection so satisfying that we're left without anything else to ask for. Dual Intensity: The Profile Dual Red Halos are designed to run full-time in their dim setting, and [when signaled to do so by your brake light circuit] double their intensity. They can also be wired for use as the intense mode only if that's what you want. Just wire up the appropriate input(s) and you're ready to roll! Intensity and Uniformity: Profile's unique blend of phosphorous silicone coats the front face of the Dual Red Halos and is responsible for their neutral "white when off" look and their amazing intensity which is unlike anything else on the market. The proprietary coating process ensures perfect uniformity without any hot/dark spots, bumps, runs, or other imperfections found on coated rings found elsewhere. Simplicity: Wiring the Profile Dual Red Halos is super easy. Their advanced LED drivers control all of the functions and only require a 3-wire input. EZ-Mount: There are three micro-mounts integrated into their backing, making these the easiest and cleanest halos on the market to install. (Patent Pending) Now you can forget about failing glue or wires wrapped around the face of your angel eyes. Don't be "that guy" with dripping glue or picture hanging wire visible inside your tail lights. Reliability: The innovative Hybrid-LED technology delivers a virtually infinite lifespan of 50,000 hours. That's almost six straight years! Because they're based on much more stable and mature SMD-LEDs; they are considerably more reliable between hot/cold cycles compared to "new" COB based halos. The drivers are refined to work reliably on all modern cars/trucks, and are completely potted inside to avoid moisture-related problems.
