If you have a telescopic stern light like this: be aware that the wires inside can pull free and stop the light from working. Mine is a bit over a year old and the light started to flicker, + wire at the lamp pulled part way out of the crimp connector so I reattached, soldered (thinking to myself, what a shitty design, springy coiled wire constantly pulling on the crimp connector with no strain relief) and it worked for a few trips. Well, I launched at 1am last night and,,, no stern light again! WTF, the other end of the wire, at the socket, ripped off their soldered connection. After 1/2 hour trying to fix the POS I was able to fish the wire out of the 1/4" hole, strip it and shove the brass contact back into the plastic plug, trapping the wire and making connection. Not only frustrating, but it could pose a safety problem if it happens while your out on the water.
