Adding underwater lights

[Jimmer]

I have underwater lights that I added to my 2016 AR192. I added them direct to the battery, I am now thinking that wasn't the way to go. The switch get hit every so often by accident and the light get turned on while the boat is on the trailer, not good. So far I have caught it every time, so no battery drain or burnt out lights. What I want to do is route them so the battery switch has to be on for them to be on. My dilemma is, I think I know how to do this, but I am not sure. I have looked at youtube, but all I could find are videos that show how to wire them the way did it. I would like to use the existing fuse block controlled by the battery switch. Is that a good idea?

Just use a relay. Get your hot wire from the battery switch, and use your existing toggle to trigger the relay. Minimal rewiring needed.

Seanmclean, thank you for the info.

Why wouldn’t you just move the positive lead that is currently connected directly to your battery to a terminal on your battery switch? Can you post pictures of your battery wiring and switch?

Maillis, Here are pictures of the battery switch, wiring and batteries. Probably would have to put a bigger end on the light wire to fit over the switch
terminal.

I think the big studs on the switch take a 3/8 id connector.

Yes just crimp a a 3/8” lug/ring onto that wire and attach it to the COM (common) terminal and you should be all set to have the lights only work if the battery is turned on.

Maillis, Thank you for the idea. Will give it a try today.
