Done right: These should make you second guess simply adding LED bulbs to your stock housings. The XB LED Sidemarkers 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 Silverado HD or Sierra HD LED side markers on the market today.

Brighter: You have already done an LED upgrade to the headlights, the fog lights, and the tail lights on your Silverado HD or Sierra HD, so does it make sense to keep the sidemarkers 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 sidemarkers for your Silverado HD or Sierra HD 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.

OEM Plus: We live, eat, and sleep lighting upgrades. While the Silverado HD or Sierra HD LED sidemarkers 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.
