Video Transcript for What to Know About the Thinline LED Trailer Clearance or Side Marker Light

Michael: Hi, there. I'm Michael with etrailer.com. Today we're going to take a quick look at the ThinLine LED trailer clearance or side marker light. This will serve as either a clearance or a side marker light. It is a P2 rated product. It's going to produce a 90 degree beam pattern.

You will be able to see it from the front, but not from the side. You won't be able to use it as both a clearance and side marker light simultaneously, but you will be able to use it as either/or, depending on how you have it mounted.This does have an amber acrylic lens with two Amber LEDs on the inside to provide that light. That Amber lens does meet up with the durable polycarbonate base. Those two are sonically sealed together, so it's going to be waterproof. If you want to put this on your boat trailer or something like that, where it's going to be submerged, it's going to be just fine.

Having those two LEDs in there, it's going to make this very durable, as opposed to your older style incandescent lights, which had that brittle filament that often would break. Your LEDs are going to last about 50 times longer than their traditional incandescent lights.These do come with a lifetime LED warranty. You can trust that they're going to hold up well for you to do a good job. Plus, those LEDs are going to be a lot more efficient than your old incandescent lights. They're going to provide a brighter light with less power draw.

These are only going to draw about 0.051 amps on a 12 volt circuit. They are going to be compatible with your 12 volt DC systems.As far as getting this mounted, it's going to be very easy. Now you will need a bracket, which is sold separately, but with that bracket, just plug it in place. You can see on the backside, we've got those two posts that will accommodate your industry standard one wire or two wire plugs, which again are sold separately. Very easy to get hooked up.

I'll use my little wires here to give you an idea of how bright this is going to be. You can see those two LEDs do light up well, even in the dark, going to give us a nice, bright light to make sure that other motorists are aware of where our trailer is.Our overall dimensions, looking at just shy of 4" in total length. Let's call it about 3-7/8". Our height, looking at about 1-1/4". Then our depth, it's going to be just shy of an 1". I'm going to call it 7/8", but right about an 1". A great option if you are wanting to replace a side marker or clearance light. It's going to hold up well, do a good job for you for a nice long time. That's going to complete our look for today. Again, I'm Michael with etrailer.com. Thanks for watching..

See what our Experts say about this Optronics Trailer Lights

  • Will ThinLine LED Side Marker Light Fit A A65PB Black Molded ABS Bracket?
    Yes, The ThinLine LED Clearance or Side Marker Light # MCL61RB will work with The Black Bracket # A65PB. The side marker light is 4 inches long by 1-1/4 inches tall by 1 inch thick. The light has a snap-in surface mount with the bracket # A65PB. The Single Wire Plug for Thin Line Series Trailer Clearance and Side Marker Lights # A65P will help with the grounding which is through the mounting hardware. The Amber version light # OPT66FR will work with the same bracket and single wire...

  • What Bracket and Wire Plugs Fit The Thinline LED Trailer Clearance Light # OPT66FR?
    You will need the Bracket # A65B with either the 1-Wire # A65P or 2-Wire # A46PB for the Thinline LED Trailer Clearance Light # OPT66FR.

  • How to Install Optronics MCL61AB LED Trailer Marker Light
    Did you mean the Optronics MCL61AB which we offer as part # OPT66FR? I suspect that the extra white wire you mention is simply an additional ground wire. To wire the # OPT66FR, you'll need a mounting bracket like # A65PB. The lamp grounds through the bracket's mounting hardware (as long as its mounted to the trailer frame or to metal that's in direct contact with the trailer frame) and the black wire goes to the running lamp circuit. You can see an install video by clicking the provided link.

  • Recommended Amber LED Light that Measures 4 Inches by 4-1/4 Inches
    Hey Michael. I have a P2 rated light that fits all your specifications but I do not have a PC rated one. It is the Thinline LED Trailer Clearance or Side Marker Light item # OPT66FR. This Amber lens LED light measures 4" x 4-1/4". It has a P2 rating so the light is going to spread out 45 degrees to each side of its centerline but not 90 like the PC rated lights. You will need the Bracket item # A65B with either the 1-Wire item # A65P or 2-Wire item # A46PB for mounting the Thinline LED...
