Wesbar LED Combination Tail Light Diagram

Sealed, Waterproof Trailer Light

The waterproof construction of this light makes it ideal for use on trailers that may be submerged, like a boat trailer. The circuit board is sealed, which means that water will not damage the diodes or circuit board.

Combination Lights for Trailers Over 80" Wide

Flatbed trailer over 80" wide with combination tail lights

If a trailer is 80" or wider at its widest point, then it requires rear clearance lights in addition to basic trailer lights. These clearance lights indicate the width of the trailer when it is viewed from the back.

To meet these requirements on a flatbed utility trailer where the bed extends past the wheels, you can install combination trailer lights that include the rear clearance function. For proper mounting, the lights must be installed at the widest points on the rear of the trailer - one on each corner.

Surface-Mount Light

Surface mount light

Surface-mount lights install flat against the surface of the trailer, so a hole does not need to be cut into the trailer for the light. This type of light is installed using a flange or bracket that has mounting holes. And mounting hardware is used to secure the light to the trailer.

Video Transcript for Wesbar Trailer Lights - Tail Lights - 271574 Review

Today we're going to be reviewing part number 271574. This is the Wesbar LED Waterproof Low Profile Taillight for the right hand side of your trailer. The LED system is a really great system to have in place. LEDs last longer and burn brighter than incandescent lights. They're also going to use less power so they're a little bit more energy efficient. This main section here is going to contain 16 diodes which going to be your LEDs. Then you're going to have a side marker strip over here with an LED system on it as well.

Again, this is for use with trailers over 80 inches. The mounting hardware is included. Here on the back it's going to have the three mounting slots. The distance that we have center on center between two of the slots is going to be 2 inches. It's going to be the same for the other side as well. Which from outer slot to outer slot is going to give us a measurement center on center of 4 inches.

The overall length of the light measuring from end to end is going to be 8 inches. The overall width is going to be . Actually we're going to measure the back of the housing. A little bit more squared off. Gives us an easier measurement.

Looks like it's about 3 3/8 of an inch. It's going to give us an overall depth of from front to back of 2 7/8 of an inch. Now here on the back it's going to expose the three wires. You're going to have your white wire with the ring terminal. This is going to be your ground wire. Your red wire is going to be for your stop and turn signals and then your black wire is going to be for your taillights.

We're going to go and connect this to an external power source. That way you can see what it looks like with power running to it. Then we'll also be able to turn off our overhead lights. That way you can see it in a low light setting. This is going to be our taillight function. Again, you got that side marker here on the side. The LEDs send out a nice consistent signal. They have a quicker response time so when we apply our brakes the main section there illuminates for a brighter more consistent signal. It's going to provide that same function when we activate our turn signals as well. That's going to do it for today's review of part number 271574. If you need one for left hand side of your trailer you can find that at etrailer.com with part number 271575. That's going to do it for the LED Waterproof Low Profile Taillight from Wesbar. .

These WESBAR LED waterproof combination tail, brake, and turn signal lights are BRIGHT! I decided to upgrade all my 20+ year old incandescent trailer lights primarily to eliminate the hassle of replacing bulbs and light modules every year or two. I was extremely pleased to find that in addition to longer life, they are extremely bright and I feel much safer now when pulling my boat trailer day or night. 675522

It's been a year since I purchased and installed these trailer lights. Installation was simple, they look and work great. I didn't realize when I purchased them that they didn't come with a reverse light, but that's my fault. The lights are bright and not blinding and look like they came stock with the trailer. Great product and no complaints here. 293997

Great tail lights. I have installed the lights on two different trailers. Underwater lights are the only lights that should be installed on trailers regardless if they are submerged or not. Very happy with the product. 267148

LED trailer light-Delivery was very fast, product was as described only problem was the hole in the fitting on the end of the ground wire was not big enough for the furnished bolts. 213956

I ordered a boat trailer tail lite. Order was handled in a very professional manner by Jena. She even followed it thru the shipping process and it was received in 3 days packed perfectly. I read some negative reviews, so I was a little skeptical, but I gave Etrailer a try and things couldn't have worked out better. As in most cases, skeptics are their own worse enemies...They don't order correctly, or don't know what they're ordering, or don't follow procedures. I would not have second thoughts about ordering from Etrailer. 182697

My Wesbar taillight upgrade to LED fit perfectly and installation was a breeze.My salesman was knowledgeble and helpful.They shipped same day and arrived earlier than I expected.All around a seamless transaction. 144413
