Video Transcript for Optronics Sealed Mini Rectangular LED Trailer Clearance Light Review

This is Optronics sealed, mini rectangular LED trailer clearance light, part number AL91RB. The lens is sealed and waterproofed against the housing of this light. Inside are three LEDs that draw a total of 0.051 amps at 12.8 volts. It is designed to snap into a mounting bracket that will connect our ground connection. Then you would use a single pole wire lead to connect to your running light circuit on your trailer. Now we are going to hook up the light to a power supply and show you how it looks. Connect one of the contacts to our ground and the other to our power. Next we will turn off the overhead lights so you can see how bright the light is. And that does it for Optronics sealed, mini rectangular LED trailer clearance light, part number AL91RB.

I cant tell you how disappointed I am...........that I did not find out about etrailer.com until now. The LED marker lights that I installed on my Haulmark Lowhauler are simply amazing. They are brighter than the big name companies truck lites out there that I had bought. It is too late for me to return my other lites but I went ahead and changed all the lights on my Nautique boat trailer with your products. It is the difference between night and day. Thanks for the great products. You have gained a NEW LOYAL customer. Speaking of that... I placed another order today. Thanks again!!73758

I wish I knew the product required additional components to mount and connect. After receiving the product I discovered this. This should be an apparent product bundle and I think the website should communicate this.65959

The product is excellent, however, it requires a separate mounting bracket, which is not included. I had to find out from a call to customer service after recieving the item. The customer service rep knew immediately what I was talking about, and I was able to order the brackets right away from her.17586

  • Should LED Trailer Lights be Mixed with Incandescent Trailer Lights
  • One main difference between LED lights and incandescents is the amount of power each one draws. I did a little research and found that if you were to have LEDs and incandescents on the same circuit, it would be too much power draw for the LEDs without using the proper resistors to compensate for the differences. It would be best to replace all the lights to one type or the other. However, if one of your stop/turn lights was LED and the other was not, that should be fine (provided both were de

  • Are Mounting Brackets Needed To Install Optronics LED Trailer Clearance Lights # AL91RB

The brackets are sold individually, so you will just need to order the same quantity as the number of lights you have. I have linked a video that show the installation of the Optronics AL91 Series Lights.

  • Will Optronics Side Marker Light # AL91RB Mount in Existing Rubber Grommets on Trailrite Trailer
  • The Optronics Clearance/Side Marker Light, part # AL91RB, will mount in the rubber grommets that your Grote 4641 lights are installed in. I looked it up in the industry cross reference for lighting and it listed the # AL91RB light as fitting in your grommets. The rubber grommet we offer for the # AL91RB light is the Optronics Flush Mount Grommet, part # A91GB. This is a rubber grommet that is used when mounting the light flush to the trailer. It measures 3-5/16 inches long x 1-15/16 inches wi
