Optronics AL91 Series LED Marker Clearance 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.

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.

You wouldn't think something like getting replacement running lights would be that complex but frankly it is. With the various options and manufacturers its a nightmare. After searching the desert of the internet for correct information I stumbled upon this oasis of information from etrailer to get the right lights and mounting brackets. I now understand what the "e" stands for in their name, they make trailer stuff "easy".


Replaced all original, loose ground, flickering lights with the Optronics. The trailer is a 2008 Sundowner and have always had issues with the marker lights. Should have done this years ago.


Great company to buy from. They ship promptly, and are there with long customer service hours to answer questions.

Fine. Still bright and reliable. Very low current draw which helps greatly since I have a very long trailer. The old incandescent lights caused significant voltage resulting in dimmer lights at the rear of the trailer. Expensive, but worth it.
Stephen - 04/18/2022


Looks great and easy to install.


Ordered several different types of lights. Website is friendly and order was shipped almost immediately. They are not installed but extremely pleased. Make sure you know if the light you need needs mounting brackets or wiring as some items dont come with it. Will order through them again any day.

I ended up selling my trailer after I rewired it. But the guy who bought it still loves them. Bright and affordable. When you order them with the brackets it was a chore to find a screw head thin enough to allow the light to properly snap into the bracket. Still a great buy
Jon L - 12/11/2016


These lights are bright, easy to mount, and inexpensive. They appear to be tough enough to be mounted on trailers that are subject to gravel and dirt thrown up by the towing vehicle. etrailer can get them to you in just a few days. (Longer if USPS is involved in shipping) Don't forget to order the mounting bracket for installation.


great light for the price direct replacement for ezloader clearance light

1 year saltwater light is still bright and like new
Wayne - 06/07/2020


Parts were as advertised , matching original equipment on my trailer , and work just fine ,I like the extra length of the wiring they include with their LED lights. The shipping prices were fair and much appreciated from any online shipper. I’d buy from etrailer again


So far so good. Replaced wesbar lights no longer available/desirable. These are direct swaps into the rubber grommets and are sealed on the back. Used watertight, heat shrink butt connections to existing trailer with g and back in business. Here's hoping they hold up under repeated dunking in water on boat launch and recovery.


clearance light fits perfectly. The tail wire allows for quick and secure installation. I used the plug in style previously but they continually unplugged and damaged the connector.
Steffen G at trainer was most helpful in assisting with the proper selection and for filling the order. Packing was excellent. They arrived as scheduled. The online tracking is exceptional.
I highly recommend etrailer and i shop here first for all my trailer needs.
keep up the great customer service,


Exact replacement for two of the amber side lights on my 2004 Trailstar boat trailer, except LED! The other online sites don't have these. So glad I found your website.


I have to say it's an absolute pleasure dealing with etrailer. Not only did my package arrive on time as promised but the experience of dealing with the people at etrailer such as Tommy and Dani made it that much more of fun experience. There was not a problem with answering my questions if they did not know the answer they found out the answer and got back in touch with me. Their prices are great their products are good quality and there's so many good things to say about the company that I could go on and on. Keep up the good work and I will be doing all my trailer business with etrailer. Just check out their website and see how much more they have to offer.


products are good quality, in expensive, and customer service by Nicole was great. I was handled in 10 minutes .


etrailer has great prices and delivery on its merchandise. Thanks for the excellent service and I will
recommend etrailer to people I know.


Excellent product! These clearance lights are exactly the same light that was originally installed on my horse trailer. I got just what I ordered quickly with no hassles. Really appreciate the great service.


Sarah was an excellent help in finding the right replacement lights for our trailer and she insured they showed up as promised on Monday. Thank you for such wonderful service!

  • How to Wire Optronics Red Clearance/Side Marker Light AL82RB
    The black wire on Optronics marker/clearance light # AL82RB is the power wire and will connect to the running light circuit on trailer and the white wire grounds to the trailer frame. It is not DOT approved for use as a turn signal or brake light though. I have included a link to the lights we carry that are approved turn signal/brake lights.

  • Recommended LED Marker Lights For Kargo Max Trailer
    I recommend using LED side marker lights part # AL82RB. This is a 2-wire PC-rated light that measures 2-1/2 inches long x 1-3/16 inches wide x 7/8-inch deep. If you are looking for an amber light I recommend part # AL82AB. This is the same as the red light I mentioned above but has an amber lens.

  • What Replacement Amber/Red Side Marker Lights Fit My Boat Trailer?
    I have a solution for you. After much research, the Optronics brand is the closest we have to the dimensions you are looking for. You are absolutely correct that the Optronics lights have a bit wider dimensions than your lights. The # AL91RB and the # AL91AB measure 2-1/2" x 1-3/16" x 7/8". With that being said, it is often much easier to replace the lights altogether than to look for an exact match of replacement lens. For the full units, I recommend the # AL82RB and the # AL82AB. These...

  • Replacement Red and Amber Rectangular Clearance Lights Needed
    Thank you for reaching out and for the photos! From what I'm seeing it looks like the replacement red and amber lights you're looking for are parts # AL82RB and # AL82AB respectively. These are LED lights that measure 2-1/2" long x 1-3/16" tall x 7/8" deep and install on bases like what you have in your photos. The lights come with bare wires so you'll need to cut off the white connector at the back of your lighting and then splice these lights to the connector using butt connectors like...

  • Red and Amber Trailer Clearance Lights That Measure 2-1/2 Inches x 1 Inch
    We have trailer clearance lights that are about 2-1/2" x 1" but clearance lights will only have 2 wires (power and ground) so there are no 3-wire clearance lights. Tail lights can have 3 wires but there are none that are as small as what you mentioned. So I recommend using 2-wire lights, which are the following: - Red Lens: Optronics Mini ThinLine LED Clearance and Side Marker Light # AL82RB - Amber Lens: Optronics Mini Thinline LED Clearance and Side Marker Light # AL82AB For a mounting...

  • Replacement Optronics Clearance/Marker Lamps to Replace Peterson PM152
    The Optronics # AL82RB would work as a replacement for the Peterson PM152 lamp, but from what I found on Peterson's website, the PM152 features two prongs on the back which is more like the # AL91RB from Optronics. Either would work for you, but I'd use the # AL91RB, assuming you have the 2-wire pigtail like # A46PB already wired up on your trailer.

  • Optronics Trailer Clearance Light Similar to AL 91RB that Installs With Smaller Hole Drilled
    The Optronics clearance light part # AL91RB in all of it's configurations would require a hole to be drilled for a harness like the part # A46PB to install with a grommet like the part # A91BOB. There isn't a way to mount it flush without drilling. If you used the part # AL82RB instead though it would require a much smaller hole be drilled since the entire harness of the other setup gets ran through the hole.
