Purchase SEALED LED lights as replacements and use butyl caulk to set them in place. The older incandescent lights would leak water in around the front lens and then this water would leak around where the wires came in to the light. The sealed LED lights prevent this from happening and can actually be submerged without leaks. IN addition the LED lights will be brighter and least pretty much forever.
I ordered all new SEALED LED lights for my Monaco coach and they were about $5.00 each. Be sure to get TWO wire lights since you cannot use the fiberglass cap as a ground.
