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. .

  • 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.

  • 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...
