Cab Roof Light Question

[Dug]

Yes , just replace the bulb. You pull the whole unit up , it should pull up and out of the hole in the roof with two fingers. Then out of the bottom of the light assembly , turn counter clockwise the bottom where the wires are attached. The socket and bulb will then come out of the lense assembly . Then pull straight out on the bulb and install a new one . Put light socket back into lense and pop back in hole in roof.
