Profile Performance: The automotive aftermarket's best name in LED Lighting and when it comes to Switchback LED Strips; 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 Pivot Switchbacks are perfection so satisfying that we're left without anything else to ask for. Switchback: The Pivot is designed to run full-time in their bright white setting, and [when signaled to do so by your turn signal circuit] flash amber. When the signal stops, they will automatically return to white--just like any modern luxury car would. They can also be wired for use as a bright Amber-only or White-only strip 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 Pivot strips 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 strips found elsewhere. Super Amber: Their smart LED drivers are programmed to temporarily bump the power to the amber LED's when they first illuminate. So what? You get the best of both worlds. A switchback strip with an insanely bright amber turn signal, and also one that can work reliably as a full-time amber strip! (because the over-driven amber output is so brief, chip reliability is unaffected) Simplicity: Wiring the Pivot strips is super easy. Their advanced LED drivers control all of the functions and only require a 3-wire input. The white wire receives a constant 12V+. The black wire is grounded, and the orange wire is tapped into the turn signal circuit. 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 strips. The Pivot drivers are refined to work reliably on all modern cars/trucks, and are completely potted inside to avoid moisture-related problems. Flexibility: Built on a ribbon-based circuit board that's got a side profile of less than one millimeter thick and backed with 3M adhesive. The Pivot strips are not only the most flexible LED strips on the market, but they can be mounted in tight spaces too. Finally you can forget about those bulky, unattractive silicone switchback strips for good. NOTE: These cannot flex side-to-side, only front-to-back.
