Complete Exterior Lighting Refresh for 2000 GMC Sierra morsunled.mystrikingly.com

When upgrading the bumper lights, it is important to note that LEDs draw significantly less current than halogen bulbs, which can cause hyper-flash—a rapid blinking condition indicating the vehicle's flasher relay thinks a bulb is burned out. This can be corrected by installing an LED-compatible flasher relay or adding load resistors to each circuit. The sidemarker lights, which mount flush with the front fenders, are equally straightforward to upgrade, typically requiring only a screwdriver to access the bulb socket. Replacing both the bumper lights and marker lights with LEDs ensures your Sierra is seen from all angles, day or night.
