please provide instructions on how to replace the rear signal light bulb 2001 ford f150 supercrew
Bob, unfortunately we don’t have instructions on how to replace the rear signal light bulb. Hopefully someone in the Modified Life community will be able to help you out. Good luck.
there are two holes in the tailgate frame, inside are the bolts that hold the turn signal housing. Use a nut-driver to loosen the 2 bolts and the entire housing will slide out.
Then you can remove the bulbs.
Dana, thanks for the light bulb change information contribution!
