This is a pretty simple mod. In this writeup, I'll break it down, just in case someone gets stuck during their install. These lamps are nice and bright, with a nice clean light coming from the LED's.

2005 Chevy Colorado Z71

Take the mirror down using a Torx bit, and remove the wiring harness from the rear of the mirror.

Remove the lens covering the existing lamp.

Remove the existing bulb using a small screwdriver (NOT NEEDLENOSE PLIERS), and use a set of 45° needlenose pliers to squeeze the "socket" tabs back together, allowing the LED plug to fit snugly in the socket.

Plug the LED harness into the socket and shove the excess wire down into the hole where the bulb used to sit.

Remove the adhesive backing from the LED and press into the reflector until the foam compresses and the light is positioned the way you want it. Reinstall the lens cover, wiring harness, and mirror. Done.
