Installing LED clearance/marker lights on your trailer

How to for swapping out your clearance lights for LED's. This is for a boat trailer but, should be pretty much universal.

First take the old lights off. Unplug it inside the frame.

Thereís a single nut on the underside of the fender, a 7/16Ē socket worked for me. Thereís also a ground wire on the bolt, slide it off and donít forget that itís there, weíll need to hook it back up.

Then the light will just come right out.

Hereís the old light. Your new light most likely wonít come with a connector on it, and the wire isnít long enough anyway. Snip the wire off the old light, I cut mine fairly close to the back of the light so as to have as much slack as possible. It proved to be a hair too much, and I had to zip-tie up a little slack under the fender. Not a big deal. Better to have a little much, than not enough.

At this time, itís also a good idea to test the new light, before you go through hooking it all up. Just in case you got a dud from the storeÖ. Just touch the post to the neg. on your battery, and stretch the hot wire over to the positive. You should be able to test it w/ just a 9v battery as well, if you have one laying around.

Strip a little of the shield back from each, twist them together, and solder them together. If you donít have a way to solder, butt connectors will do, but I would find some waterproof ones. Donít forget to slide your heat shrink on before you connect them.

After soldering them together good, I slid my heat shrink up over the connection, and heated them up. I doubled up with a small diameter one that fit just over the wire, and sealed It up. Then used the next size up as well, over the top of that, and heated it upÖ so Iím double protected. So you should have something that looks like this:

Now weíre just going to do everything in reverseÖ Put the light back in. Slide the wire through one hole, and bolt through the other. Thereís also a hole in the frame for the wire to go through, feed it through there too.

Remember, donít forget to slide the ground wire back up over the stud before you put the nut back onÖ Muy Importante.

Plug your connector back up, and if you have any slack in the wire, zip tie it up out of the way.

Now youíre done!! Just repeat as needed.

I used some similar lights on my son's power wheel Kawasaki KFX 4 wheeler. He wanted some lights like daddy's Jeep. Plan to put some red LEDs under it also, but haven't had time.
