How do you remove the fog lights on a 2003 Toyota Tundra to replace the bulbs?
If they’re OEM the dealer should be able to give you an instruction sheet. Or their parts department should be able to gibve you an “exploded view” drawing showing how all the parts go together. For dealer-installed accessory lights the manufacturers provide installation instructions to the dealers, as well as instructions on changing the bulbs.
If not, see if you can find out who manufactured them and ask the manufacturer.
