So the marker lights on top of my cab quite working. Any ideas?? are these fused? bulbs are good. Where to start??

You got it .... That's exactly where you start. CHECK FUSE. Highly unlikely all five bulbs blow at the same time

Then you pull your interior down. If the fuse is burnt? You have to find out WHY. (usually a short somewhere in the circuit )
If the fuse isn't burnt (still good) You need to still pull your interior apart to source out the circuit interruption

Thats where I would start.
