How to Replace Toyota Tacoma Side Marker Lights
Replacing the side marker on older Toyota Tacomas was not as complicated as replacing them on newer ones, since the side markers are now combined in the headlight assembly. Older Tacomas had separate marker assemblies that simply unbolted and popped the guide pin out to replace the bulbs. You can save a lot of money on labor by replacing the markers yourself, but it's recommended to replace both sides while you're at it.
