Replacing a brake light bulb for a 2006 chevrolet equionx

This is almost correct...instead f straight back pull straight out from the side, right light, pull to the right, left bulb, pull to the left.
Worked great.

I just replaced the p/s brake light:
1. Pop off the tabs that cover the screws. (flat screwdriver)
2. Unscrew both screws. (philips-head)
3. There is a metal post attached to the light assembly located towards the front of the assembly pointing in towards the center of the car. This post fits into a rubber grommet that is attached to the car. I had to wiggle and rock the assembly to get the post free from the grommet and the assembly off the car, by pulling to the right.
4. Re-assembly requires lining up and inserting the post back into the grommet (use your best Beavis and ******** sound effect now). Put the screws back in and don't forget the covers.

After lifting the tailgate and removing the two visible screws for the taillight you just need to pull the taillight straight back. There are two guide posts on the taillight that kinda lock into two plastic grommets.

JUST A FYI! THERE ARE PLASTIC CAPS COVERING THE SCREWS! THEY POP OFF WITH A SMALL SREWDRIVER THEN YOU CAN GET TO THE SCREWS THAT HOLD THE ASSEMBLY!!
