Video Transcript for Blazer 7 Function Trailer Tail Light Installation

Today we're going to be taking a look at the Blazer LED trailer tail light. This offers 7 functions and it's submersible. This is designed for the driver's side which will have the clear lens on the bottom for the license plate. Part number is C7483RTM. For the passenger side without the clear light on the bottom, part number will be C7493RTM. Here you can see what our lights are going to look like installed and we've got our running lights on now so you've just got like the tail light function running.

Gives you a nice clear light. Also going to have the side marker light there and then you can see there in the bottom it's got that nice white light. It's really going to illuminate that license plate for us and keep us legal. These are going to work out really well for both sides of the trailer and the great advantage to an LED light versus an incandescent style light, is that these have a very minimal power draw so we're not drawing a lot out of the vehicle. It doesn't take a lot to operate them. Now the LED lights tend to be a clearer kind of a light, really gives you a nice bright light as you're heading down the road, where the incandescent tail lights look kind of almost like the lens was a little bit hazed over.

A real nice clear pure light. The looks of these really stand out versus a standard incandescent light. Now to begin our installation, of course we want to have our old light out of the way. I'm going to take these 2 carriage bolts and these are going to slide up right in the back of the light, so a little groove there that we can allow our wires to pass through so you don't have to worry about getting them pinched. You really want to pass those carriage bolts through the attachment points there and then again double check to make sure your wires have come down. Now for our ground wire, I'm just going to loop that around.

That will provide us with a good ground rate there on the trailer. Then replace on one of our flat washers, one of our lock washers and one of our nuts. I'm going to do the same thing for other stud there. Now we just need to grab a 10mm wrench ratchet and get that tightened down. You're not holding a lot of weight here so you don't have to get them overly tight but we do want to ensure that we crash that lock washer down all the way and also that we've got a little tension. That's going to be nice and secure there.

Then we run those 2 wires over. We're going to use part number DW05744 to make our connection which is going to be a Deka Heat Shrink Butt Connector. Now we want the tail light, whatever color it might be on your trailer, in our case it's brown, we want to connect those together, get that crimp down and then give it a good pull, make sure it's connected properly. I'll do the same thing for our yellow wire which in this case our trailer also has the yellow wire but this should be your left turn and your left brake signal that you're looking for if they're not color matched. Now we want to use a heat source, either a heat gun, mini torch or just a lighter here. I want to get these to shrink down. It's going to give us a good superior watertight connection so we're not going to have to worry about any moisture getting in there causing corrosion down the road. Now we'll do the same thing over in the other side although our yellow wire should be a different color, usually green. It's going to be for your right turn and your right brake but again, check it out just to make sure. Now with this side installed, we're just going to make the connections the same way we did on the other side. Now if you want to you can just get that kind of secured up. There's not enough slack there for me to really worry about. Since it's sitting up above here it's not going to get hung on anything, so we're all wrapped up. Let's get it outside and hooked up to a vehicle and see how the lights work. There's our headlights. We'll do our left blinker now, our right blinker and our brakes. That's going to complete our installation of the Blazer LED submersible trailer tail lights.

The parts that were delivered were exactly what I expected, they fit very well & seem to be made to last many years. With one exception, the bushings with the 1/2" bore fit loose within the eye of the leaf spring. The pricing was very competitive. Delivery was prompt and on time. 770731

One would be hard pressed to find better Tail lights for a utility trailer. Super easy to install & hook up. The lights are bright & these are even submersible. I broke my driver's side light & even though the break involved some of the housing only, the lense was not broken and the light still worked perfectly. I didn't really even have to replace it, but it was held in position with clear packing tape and that probably wouldn't last long, so I got a new one. These are without a doubt the best trailer tail lights available, period. 569873

Ask the Experts about this Blazer Trailer Lights

  • Troubleshooting Peterson Tail Lights on Boat Trailer That Keep Burning Out
    It really all depends on what trailer light kit you have installed on your boat trailer. Some kits are designed to withstand submersion and other kits aren't. If you can let me know what kit is on your trailer (not just the type of bulbs you use) I can help you determine if it is submersible (granted we carry it). Another thing to note is that you need to make sure your trailer wiring is unplugged before backing the trailer into the water. Even if your lights are submersible, if you...

  • 2012 Jeep Liberty Headlights Cause My Trailer Turn Signals and Brake Lights to Fail
    It sounds like there may be a couple of issues going on here. First, It is very common for LED lights like # C7493RTM & # C7483RTM to remain on very dimly whenever the trailer is connected to a vehicle, even if the ignition is turned off. The only solution is to disconnect your trailer when you will be parked for extended periods. Now let's address the bigger issue. When turning on the vehicle's headlights causes one or more of the trailer lights to stop working the number one culprit...
