I would rather work on trailer lights than anything.

I'd rather work on trailer lights than sit in a hot tub on a cold day.  Dang those things can be a PIA.  I need a beer.

When I lived in Washington state I used to trailer my boat to saltwater launches and I had my share of trailer light issues.  You have my sympathy.

I've been pulling trailers for 50 years now.  Maybe three of them free of any trailer light problems.  There has to be a better way.  I'm thinking battery operated LED lights with RF controller and no more wires or bulbs .

Or just take up golf.

I've hit golf balls that if i'd wrapped them in bacon Lassie couldn't find them.

I have a small utility trailer that gets loaned out a lot.  Seems like I spend more time working on the lights, stand, woring, re-weldling the flooring etc. Than I do using it.

I know!

Would get a new harness and some sealed  LED lights if your boat trailer has wiring issues. Only took an hour or so to replace the old lights & wiring  when I did mine this summer.

I'll spend about 3.5 minutes trying to find a trailer light problem, if it takes longer than 10 minutes to fix the issue then it gets a whole new light kit/harness/the works.   

Ain't nobody got time for that BS.

Replace your lights with LED versions and replace any of those quick splice connectors with some good waterproof butt connectors and then coat the connectors with some liquid electrical tape after they cool down and you shouldn't have any lighting issues for a long while. Also, make sure your ground wire is mounted to the solid frame of the trailer and not the swing away tongue, if your trailer has one. I did this to my new boat trailer shortly after I got it in the summer of 2014 and the only issues I've had was I had to replace a couple running lights once the bulbs burned out. They are also LED now so I should be good for VERY long time as long as I don't beat them on anything to break them.
