A simple and effective way to upgrade the exterior styling of your GMC Sierra HD is with a set of Axial LED Fender Flare Side Marker Lights. These Side Marker Lights feature a razor sharp LED strip that replaces the unsightly hot spot of the factory lights. These Axial Fender Flare Side Marker Lights not only look great, but they are also much brighter than the weak factory incandescent lights for increased visibility day or night. Raxiom manufactures its Fender Flare Side Marker Lights with injected-molded ABS plastic housings for durability, and use smoked polycarbonate lenses for aggressive good looks. These Side Markers employee high output, red (rear) and amber (front) SMD LED strip lighting for super bright illumination. Raxiom ensures that its Fender Flare Side Marker Light housings are weather sealed to prevent dirt and moisture from harming the state of the art electronics found inside. Raxiom designed its LED Fender Flare Side Marker Lights to be a direct plug and play upgrade for your Sierra's original factory lights. There is absolutely no cutting, splicing or resistors required. Just pop out the old factory side markers and disconnect the wiring harness. Plug the harness into the back of your new LED Fender Flare Side Markers and snap them in place of the old ones. It's that simple!
