Done right: These should make you second guess simply adding LED bulbs to your stock housings. The XB LED Mirror lights from Morimoto look amazing. Are well-built. Have a virtually infinite life span. An unbeatable warranty, and out-perform other options..Easily making these the best F150 LED Mirror lights on the market today. Brighter: You have already done an LED upgrade to the headlights, the fog lights, and the tail lights on your F150, so does it make sense to keep the Mirror lights stock? No way. Now you can complete the package and make sure everything matches both in terms of output intensity and purity in color with these assemblies. With high-powered Osram LED's behind the optical lens, they will be much more effective both day and night compared to the OEM setup. Durable: Their UV-coated polycarbonate lens will resist the test of time, ensuring that they look good as new for many years to come. To save on cost, the cheap alternatives do not use a UV-coated PC lens and that will become obvious, quickly. We've seen them fade within a matter of months. Spend a few bucks more now, save yourself the hassle of swapping out later. Plug-n-Play: Again, there is no comparison between the Morimoto's and the generic. When it comes to wiring, these are far better quality. The Morimoto LED Mirror lights for your F150 are designed to work without any modifications. They will plug into the factory connectors. No error codes, no flickering, hyper-flashing, or radio interference. They can easily be removed and will not void your factory warranty. Sequential LED: Game Changer! The turn signal function uses amber LED's to produce a full sequential setup, which, like the XB LED headlights from Morimoto adds an awesome, modern touch. OEM Plus: We live, eat, and sleep lighting upgrades. While the F150 LED Mirror lights from Morimoto cost a bit more relative to other options in the aftermarket; as the saying goes "you pay for what you get". We've seen it all, and their fit and finish is far superior to everything else out there. Guaranteed.
