  1. Unhook trailer lights before launching ?

    I don't get it.

    Is it the brake light bulbs that get hot under water ?

    Just one more thing to forget when driving away.

    I never unhook mine, and i've never had any problems on the 3 boats/trailers I've owned. I probably just jinxed myself ;)

    an age old question that will draw different answers ;)
    personally,i've never had a problem,and never unhook bulbs and cold water could present a problem,but then again,i never experienced present trailer setup assures against that,as the lights are mounted on top of my guide on posts,so they never come close to the water ;)

    I think this rose from the fact that old trailers typically do not have sealed lights. I remember as a kid we blew lights out of our trailer all the time. More modern trailers have completely sealed tail-lights - you can't replace the bulb without replacing the whole thing.

    I never unhook my lights and have never had an issue in the past 10 years through three trailers.

    I got in the habit of leaving them plugged in, so I could see the trailer when trying to put the boat on it at night. That, and pure laziness.

    The one time I did unplug them, I forgot to plug them back in, and dragged that harness all the way home down 71, ripping it to shreds.

    My boat has sealed waterproof lights on it so I dont take them off. On my old boat it wasnt sealed but they were fine when I didnt un hook them.

    hot lightbulbs will break when they hit cold water. daytime driving will not make them hot. i unplug mine because i have a 2000 gmc w/ daytime running light which are always on. i unplug them as soon as i start getting ready to launch. but i do have 1 of the new completely sealed lights on my trailer,and 1 of the older types.

    Buy a set of waterproof tail lights and install them. You won't have to worry about them blowing out. You can buy them at auto-zone or any marine supply dealer. Unplugging trailer lights each time you launch is like living in the stone age.

    One thing that I found out with my new truck is that it will blow fuses if I plug the trailer lights in while the truck is running.
  10. A lot of new trailers as well as newer light kits make use of the LED type lights. These never get hot, last forever (almost), and are not much more $$ than incandescent lights. This means to need to unplug them = 2 less things to remember (unplugging and replugging).

    I don't have sealed lights and I do unplug before launching. Sometimes I forget and once in a while a bulb breaks. I carry spares and a screwdriver and have gotten fast at replacing bulbs, especially since I've dropped and lost half the lens screws! I recommend smearing dielectric contact grease on the harness connector, the base of the bulbs and on the + and - contacts to prevent corrosion.
