How do you replace the rear turn signal on a 2006 Pontiac g6 gt?

There are three rubber caps in the inside of your trunk. Remove the caps and with a long 10 mm socket unscrew the two two nuts and one screw. The entire light fixure slides out and you turn the bulb socket. To replace the bulb use a Silvania Long Life bulb. You pull the bulb out and push the new bulb in till it snaps. Check the light functions before reinstalling. Good luck, easy fix.
