Optronics Light Dimensions

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.

PC-Rated Lights

Diagram of light spread for PC rated light

A PC-rated light produces a 90-degree angle of light to either side of its centerline for a total of 180 degrees of coverage. This beam pattern can be clearly seen when you are standing directly in front of the light, as well as when you are standing on either side of the light. When properly installed, this type of light can function as both a front clearance light and a side marker light or as a rear clearance light and side marker light.

Product as described and quick shipping. One small item, the carriage bolt fasteners that were supplied were SS material but the nuts weren't. SS is a must for me in salt water service. Otherwise excellent.


Great replacement for the older fixtures of this same type with incandescent bulbs. I replaced 4 old style lights on my Zieman ATV trailer with these LED units, and NOW you can see me.


Item arrived quickly and as described. Choosing the correct light was easy with the information shown on web page


Perfect replacement for my Diamond City trailer.


Light only lasted 4 months, very disapp ointed.

One thing to try would be to double check wiring connections as sometimes if not secure can become loose. This item does also come with a limited warranty and so I have sent your information along to customer service.

I used these to add auxiliary tail, turn, and stop lights to my pickup truck. I'm very pleased with the results. Hopefully they'll get people's attention.


Prompt delivery and excellent customer service!


I got these led lights to replace my original trailer lights. Easy to install and a lot brighter, definitely recommend them for anyone wanting to replace there old trailer lights.

Still going strong.

Light worked great up to about two weeks ago. Running light portion of light stopped working. Still have brake and turn single light works. A bit disappointed the full function of tail light does not work. With only a year and less than 400 miles on trailer since tail light was installed.

I recommend to first make sure the ground wire of the light is is attached to a clean metal surface on the trailer frame. A bad ground will intermittently cause one of the functions to not work properly. If the ground of the trailer does not prove to be adequate you could run it up to the ground circuit of the trailer connector.

I needed to replace some of the lights on my boat trailer. The old light were incandescent and some of the bulbs had burned out, securing screws were rusted. Product was exactly what I was looking for. Links on each product web page provided very good description and product information.

Thank you for great selection and process.

I am very happy, the lights are working great, with no issues. Thank you

This light was a much needed upgrade on my boat trailer to make it look more modern and not so old. It is very bright, fit right into the existing holes I used for the old lights and wiring it up could be easier! Have yet to dunk it in the water but I'm sure it will be just fine! Great Product!

These lights are awesome. They survived a year of launching the boat over the summer and Im sure theyll survive much more. Bright as well!
Marshall H - 06/08/2017


easy ordering, arrived on time, the right part and the right fit - easy install...and looks great


Arrived fine


AAA +++ etrailer and I will get along just fine.


There were a perfect fit replacement for my 1992 Tracker Trailstar boat trailer. It had Wesbar 3348 tailights on it. These look exactly the same but they have sealed LED capsules inside. It was gonna be the same price to replace the old style bulb capsules in the Wesbar's as it was to but these whole brand new sealed LED tails. The are very clear and bright. Huge improvement!


Excellent product, Easy to install and electrical hookup. It replaced a busted LED tail light. I leave my trailer lights plugged in when I launch the boat into salt water and have had no problems with the light malfunctioning. Very good light.


Taillight matched my other trailer light perfectly. Saved me from buying a whole new set. Shipping was super fast and I would suggest your company to anyone who needs trailer products. Will definitely buy from E-trailer again. Thanks

Actually the lights say they are submersible, but they actually leaked and blew out most of the led bulbs. Would not purchase again.
Robert M - 10/02/2019


The LED trailer lights truly do make a world of difference. The only thing that I do have to say that is not a positive, is the fact that I had to drill out my mounting brackets on my trailer so these would properly fit. In other words the factory holes on my trailer did not match the aftermarket product. As far as the LED light visibility goes, again there truly is no comparison. The LED lights rock


Purchased a set of these lights as replacement/upgrades on my existing standard boat trailer lights. These LEDs lights perform exactly as described. They are completely water tight. After one full year of use, they perform as well as the day I installed them.


Boat trailer light has been submerged many times over the last year. Still burning bright and fully functional.


The light came extremely fast and etrailer shipped it before I could even check my emails. I bought the light for a friend since the damage was my fault.... he LOVED the new light so much and it was nicer and WAY brighter then the stock one. He ended up swapping the other side to this one and is planning on possibly switching out his other trailer lights. They are extremely bright, and in my opinion make the trailer safer and look a whole lot better. I will definitely use etrailer again for ANY trailer and light needs in the future and highly recommend them, you will not be disappointed!


Great product as usual from retailer. Delivery was slow but everything is slow


Flawless throughout the year bouncing along the highway and loading and unloading my boat in frigid water. Twice as bright as my previous "sealed capsule" tail lights, which I would have had to replace 2-3 times in that period.

Wish I had found them years ago!


These lights were a great replacement for the old lights on my boat trailer. The lights bolt patterns matched up perfectly for a good fit. I couldn't be happier with the product or the customer service from etrailer. Highly recommend to anyone considering buying replacement lights.


Light arrived damaged. The shipping box does not look damaged. etrailer has sent me a replacement as soon as I called.

Everything worked out great. Trailer lights are LED bright and are easy to see. Good service and a competitively priced product.
