The old lights were always getting corroded and not working. I was always having to remove the bulbs and clean the sockets. I tried silicone grease but that didn't help.
The old lights were individual units that had a gap between them. This allowed water to leak into the rear compartment.
This what it looks like with the old units removed.
I cut the old wires and crimped on the new wires filling the fittings with silicone to make the joint waterproof. The wires in the Trek were already printed with a label showing what they are.
The new units are a Bargman #47-84-104. I bought them from Texmood.com. They were $61.35 each plus shipping.
This shows everything ready to screw in place.
This is the completed view. The new fixture is one piece and has a flange all around to seal the opening. No more leaks!!!
