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.

Video Transcript for Optronics Trailer Lights - Clearance Lights - AL82RB Review

Today we're going to be taking a look at part number AL82RB. This is the Optronics Mini Thin Line Sealed LED Marker and Clearance Light. It's going to feature the nice red lens, small compact design. LED's are a great system to have in place. They're going to last longer, they're going to burn brighter and they're going to be much more efficient. They're going to make great replacements for incandescent lights. This particular light is going to feature a sonically-sealed, waterproof lens and housing.

Here on the back side it's got the two-wire design. I measured these wires and they measure about 14-1/2" long. Your white wire is going to be for your ground connection; your black wire is going to be for power. This light is TC rated. It's Department of Transportation and SAE compliant. If we take a measurement of the overall length, this is going to give us a measurement of about, I'm measuring from edge to edge, it looks to be pretty close to 2-1/2".

The width is about 1-3/16". The depth is going to be about 7/8". This does require a mounting bracket for installation. You can find those here on our website. It's got the nice little holes here on the side. You're going to engage the clips on the mounting bracket and it's just simply going to snap into place.

Typically those mounting brackets are going to mount on 2" centers. As you can see there's no mounting locations on the back of the light here or the sonically sealed housing. Those mounting locations are relied on the mounting brackets. We're going to go ahead and hook this up to our external power supply. That way you can see what it looks like with power running to it. You can see here it's sending out a nice, consistent, strong signal.

It's a really bright light for as small as it is. It looks like it is going to have three diodes, so it's a multi-diode design which is just going to be the three LED's. That's going to optimize our light output, which is another great advantage to an LED system. That's going to do it for our review of part number AL82RB. This is the Mini Thin Line Sealed LED Marker or Clearance Light from Optronics. .

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, 402005

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. 402697

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. 370480

Great on line supplier. Good prices and many products available. Fast shipping , Thanks 367126
