Roadtrek Roof Marker (Clearance) Light (old) No wonder we have a little damp evident around the inside of the front roof windows. The holes made through the grp roof for the wires for the lights are not watertight & the wires themselves seem to be acting like a straw sucking in all the water that settles in the hollow where the light units sit.
I have stuck the replacement led lights on with copious amounts of PU Cement … Ensuring it was squeezed into all the holes & totally filled all the voids in the light unit base so there is no room for water the gather in the future.
