Optronics UCL11 Series 3/4 Sealed LED Utility Light Diagram

Sonically 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 housing and lens are sonically sealed together to create a single unit, which means that water will not get into the light and damage the diodes or circuit board.

Recessed-Mount Light

Recessed Grommet Mount Trailer Light Installation Diagram

Recessed-mount trailer lights install with a grommet, which is often sold separately. These lights extend past the trailer surface and require a hole for installation. If replacing a light, you can utilize the pre-existing hole. If installing a new light, you will need to cut a hole or use a mounting bracket (sold separately) to complete the installation.

This LED is a perfect replacement for the Atwood 80909 LED in my Atwood electric tongue jack. The photo shows the 80909 on the left and the new LED on the right. Wire leads where shortened, separated, and terminals installed.


The product was well made and delivery was prompt


About a year ago I purchased two of these lights to mount above the license plate when I redid the tail lights and storage box on one of my trailers. I mounted the license plate on the storage box and had a tail light in a heavy duty box above it, so it was easy to wire and mount these lights in the bottom of the box, direct over the plate. While one of these lights would have been plenty to illuminate the license plate, I wanted two so I had a spare if one failed. I have used the trailer at night several times since then and these lights work well every time. I highly recommend them.

I use the trailer about once a month or so and the lights just continue to shine. My trailer goes through some rough terrain at times and with no shocks on it to soften the blows, it is jarred very hard. The lights have had no problems with these hard motions.

Bought these lights and found them to be priced competitively. Very satisfied with the lights and the experience buying from etrailer had all of the information I needed and was a pleasure to buy from. Highly recommended!

Still very satisfied with the product and your business. The light is priced well and plenty bright for my needs - would highly recommend to others!

Awesome lights. I put 8 (6 would have fine) of them in the bed of my long bed superduty and they light up nicely without glare or excess light. I can now line up my 5th wheel hitch and load/unload my truck bed much easier at night. Placed the lights in the factory holes below the stake pockets but since they are 7/8 inch holes I had to use different grommets (the original require 3/4 inch hole).


Exactly what I was looking for, installed in the grommets designed for back up sensors on my ranch hand bumper (my F250 truck doesn't have the sensors). Using for extra reverse lights/utility lights.


We are a fire Apparatus. Repair shop on the East Coast. We use u r lighting system all over the truck becaus. They fit most any were ca the light are good looking. An a snap to install

Lights work just fine. Thanks have a good day

Lights are amazing exactly as described. Shipping was awful though the post office tried to deliver it to the business and then left it at the post office until I called. I had to go pick it up a few days later. I had to go get it and take it to the place of business it was supposed to be delivered to to be installed. These LED lights were installed behind the lenses on my truck visor.


I was very happy with the super fast delivery, communications, and the product. The lights are not mounted yet, but I do see where they will be fun. They are to go around the boat trailer to cast light up and onto the boat as if a glow. When complete I will send pictures. This will be the light I need! Very well priced and thank you for everything! I will order from you again!!!


Great lights for my deck lights on my new trailer rebuild and adding that they match my clear lens marker lights


Outstanding! has some great products, fast shipping and extraordinary customer service. I am impressed and will be back for more!


Would work great for a toolbox or license plate light.


Great little light. It was a replacement for license plate light on my pontoon trailer. Received it quick. Great people to do business with!


Purchased these LED lights for a moonvisor conversion project. Looks like they'll do the job fine! E-Trailer's order process was easy and deliver was prompt as promised. Definiteluy would buy from e-trailer again!


Used this as a license plate light on my ATV. Just what I needed. Fast shipping and great price.


Works well as a nite light on our rv. Replaces similar original.


Drill a hole and pop in. Bright white light good for task lighting. Using as lighting for small parts drawer in the back of my work truck in place of a 12v fluorescent fixture which never worked well during the cold winter months.. Very compact and durable.


Light looks to be well constructed and sealed, similar output to a 4cp bulb, great for accent lighting or for a license plate lamp.


Very bright for their size! Got two of them just to see exactly how bright they are. I'm thinking about getting a few more and point them towards the ground as lights when I open my truck doors.


Awesome product! Have used it on my snowmobile trailer for over a year now. Fast shipping too!


I ordered 14 quality items and 13 were delivered rather quickly in good order; the 14th item also arrived at the same time in a separate box as it was rather large. It is not appropriate to comment further.


good quality ,,,,,,,,easy installation,,,,,,,,,would use these again,,,,,highly recommend


Nice bright LED lights. Easy to work with 2 wire hook up. Works very well, good product.


Nice utility light for multipurpose use.


Parts arrived swiftly and quality of materials appear well made. I am very pleased with the service and I will be ordering again soon.
