Optronics Clearnance Light Dimensions

P2-Rated or P3-Rated Lights

Diagram of light spread for P2 rated light

A P2-rated or P3-rated light produces a 45-degree angle of light to either side of its centerline for a total of 90 degrees of coverage. This beam pattern can be seen straight on, but it cannot be seen clearly from the side. So this type of light can be used as either a side marker light or a clearance light, but it cannot function as both. If you need both functions, then you must install 2 separate lights on your trailer - one as a front or rear clearance light and one as a side marker light.

Video Transcript for Optronics Trailer Lights - Clearance Lights - MC32AB Review

Today we're going to be taking a look at the Optronics trailer clearance or side marker light. This rectangular trailer light serves either as a side marker light or clearance light. It's going to feature an amber acrylic lens with reflux reflector that's built into the lens. The lens is replaceable if ever needed. It is going to have a white ABS plastic base. It's going to contain one incandescent bulb. To get the bulb out, you rotate this housing at the back, you pull that out, then you can just grab the bulb and replace that as needed.

The bulb number is 194 and it is printed directly on the bulb itself. This is a surface mount installation, so it mounts on the surface of your trailer. Two mount holes right here. Hardware is not included. You will need to remove the lens to get it mounted, though. Again, it's got the twist-in bulb socket with two wires.

One wire is going to be used for ground, one wire is going to be used for power. This is Department of Transportation compliant. It is a P-2 rated light. Taking a look at a few dimensions real quick, starting with the overall length. That's going to measure about 4 inches. Overall measurement going this direction, edge to edge, is going to be 2 inches. Then the thickness, from back to front, that's going to measure about 1 inch. When it comes to the power draw at 12.8 volts, it's 0.2 amps. The mount holes on the unit, these are separated on center by 3 inches and they are going to give us a diameter of 1/4 inch. We are going to go ahead and hook it up to power.

That way you can see what it looks like with some power running to it. Then, we'll also be able to turn off our overhead lights so you can see it in a low-light setting. So, you can see here, that the light sends out a nice, consistent signal. Again, it's going to feature that built-in reflux reflector in the lens. It's going to contain one incandescent bulb that is easily replaceable, if needed. That's going to do it for today's look at the Optronics trailer clearance or side marker light..

This is the exact replacement for my lights on my travel trailer. So now I know where to look to buy more replacement parts for my trailer. Very fast shipping too. Thanks. 589872



- MC32AB
by:

I never knew there were so many different types of marker lights.......because of the application having a two wire light was imperative .....a lot of marker lights have one positive wire and use the frame as ground......this is the first time I used this company and their product descriptions and pictures are totally accurate which makes the first order the right order. Too many product descriptions are not inclusive of exactly what the product is and then not only are you disappointed that the product sent will not meet the application requirements, but also one gets mired down in return policies etc. I totally enjoyed doing business with this firm and look forward to doing more business 583921

Do you have a question about this Trailer Light?


  • Replacement for Kaper II 1A-S-20 Trailer Lights
  • We do not carry those exact parts, though we do have something with the same dimensions that should work for you. Optronics light # MC32RB is red while # MC32AB is amber. I've added links to video reviews of each light for you to take a look at.

  • Replacement Lens for Trailer Light 22368-022
  • I had a hard time finding a lot of information using the two part numbers you found both on the lens and the light base. It looks like the base number may refer to the Optronics Trailer Light # MC32AB, for which the correct replacement lens is part # A32AB. To be sure you can take a couple quick measurements on your existing lens. This lens measures 4 inches long, 2 inches wide, and 1/2 inch tall. If this does not look to be the correct lens please feel free to email me a picture...

  • Dimensions of Optronics Replacement Light Lenses A32RB and A32AB

  • Replacement Lens for 2" x 3" Clearance Light
  • The SAE number is not a part number so it is not a way you can identify a light, but since you mentioned it was 2" wide x 3" high there are a couple potential replacement lenses that could work. You will want to measure the screw holes of your current lens from center to center and if they are 2-5/16" the Replacement Side Marker Lens for Optronics ST8/9 Series Universal Mount Combination Tail Lights # A9RB can work; if they are 2-3/8" the Replacement Red Lens for MC35RB Trailer Lights...

  • Red and Amber Trailer Clearance Lights with Clear Lenses
  • You are correct, clear lenses are not made for lights # MC32AB or # MC32RB. The bulbs for both of these lights produce white light so if clear lenses were on them the light would just be white. Unless you found colored bulbs that would fit. We do have red and amber marker/clearance lights with clear lenses though. For example we have # MCL63CAB which is an amber LED light with a clear lens. Other amber options include # MCL13CA2B, # MCL-50CAK, # MCL51CAK, # MCL65CAB, # AL91CAB, # MCL17CAB,...

  • Locating Replacement Amber Lens for Clearance Light on 2007 Forest River Cherokee
  • Looking at the picture you attached I don't believe we have an exact match that will work as a replacement lens. If you are able to find a part number for the light assembly, which would be located inside the housing (not on the lens itself),I will be happy to verify this or see if we do have something that will work. Otherwise your best option is going to be to replace the light assembly altogether with a similarly sized unit. For this I recommend taking a look at the Optronics # MC32AB....

  • Replacement Amber Lens for 4 Inch Wide Trailer Clearance Lights
  • If you can provide me with a photo that lists the length, width, and height of the replacement lens you are looking for I would be able to offer a better recommendation for you but based off of the above information, we have part # A32AB which is an oval amber replacement lens or part # A44AB which is a rectangular amber replacement lens. Both of the above lens measure 4" wide. The oval amber lens is designed for part # MC32AB and the rectangular lens is designed for part # MC44AB.

  • Looking for Replacement Trailer Lamp Lens # 1A-S-20
  • I was able to find the exact replacement amber (1A-S-20A) and red (1A-S-20R) lenses. I did a Google search on kaper2 (or Kaper II), and found replacement lenses. Their replacement lenses are shown as measuring 4 inches long, by 2 inches wide by 3/4 inches high. I pulled one of the Optronics # A32RB off of the shelf, and measured it using a dial caliper. I came up with 4.013 inches long, by 1.97 inches wide by .67 inches high. I suspect that in measuring their lens, Kaper II might very...

  • Recommended Type & Size of Installation Hardware for Optronics Side Marker Light MC32AB
  • The type and length of mounting screw to use to install the Optronics Trailer Clearance or Side Marker Light # MC32AB will depend largely on the nature of the mounting surface. If there is wood behind the trailer's outer skin at the mounting point then use wood screws long enough to securely grab that material. If the underlying material is metal then use sheet metal screws. If you are using existing holes in the trailer then that may determine the size of fastener you need to use. The...

Replacement lenses for these Bargman lights are not available.

  • Replacement Trailer Clearance Light with part # AEP2 58-59 Stamped on It
  • Based on the number you listed and the fact that you referenced the Rectangular Trailer Clearance, Side Marker Light with Reflector # MC32AB it sounds like you have a 59 series clearance light on your trailer that you are trying to replace. If the light on your trailer looks like the # MC32AB and is 4 inches long by 2 inches wide the # MC32AB would work great as a replacement. I attached a review video for this light for you to check out also.

  • Availability of a Trailer Light with SAE Number SAE AP2 01

  • Replacement Clearance Lights with Reflectors for 1998 Coleman Cheyenne Pop-Up Camper
  • For your 1998 Coleman Cheyenne the clearance lights with reflectors you need are most likely the Oval Trailer Clearance, Side Marker Light with Reflector - Amber # MC38AB or the rounded rectangular # MC32AB. Both of these options are 4 x 2 inches and look like what you need based on the photos I can see online. I've attached the links to the light bulbs and amber lenses that we carry for you to compare if you simply want to replace the bulb and lens.

  • Proper Mounting Location for Side Marker Lights on a Trailer
  • The proper mounting location for side marker lights such as # MC32AB are as follows: For rear side marker lights you must have one on each side of your trailer and as far toward the rear of trailer as possible. They will need to be 15 inches or more above the ground. For front side marker lights you must have one on each side of your trailer and as far toward the front of trailer as possible. These too must be 15 inches or more above the ground. So, yes, you can mount them about...

  • Replacement Light Recommendation for SAE AP2-80

  • Trailer Taillight Lens Recommendation with SAE Number AP2 01
  • Do you have a picture of the light? The SAE number really isn't a part number so there is no cross reference. But most likely you are looking for a # MC32RB which measures 4 inch by 2 inch. Or for amber part # MC32AB.

  • Replacement Lens for 4 x 2 Inch Amber Trailer Clearance Light
  • We have replacement amber lens # A32AB which fits on 4x2 inch light # MC32AB. This is a more rounded design. What I recommend, if this lens does not appear to be a match, is to take a look at the 4x2 inch amber clearance lights that we carry, see link, to determine if any match your 1978 Fleetwood. It would probably be more beneficial to just replace the whole light assembly.

I could not find a reference to the part numbers you provided. If you do not believe this lens will work for your light you could purchase the whole replacement light such as the MC32AB or the 425600. These side marker lights are basically the same size as the light you mentioned and will replace the...

  • Replacement Lens for Clearance/Side Marker Light for a 2001 Coleman Pop-Up Camper
  • If the light on your 2001 Colman pop-up camper is an Optronics # MC32AB or a Peterson TW2549A this replacement lens # A32AB is the correct fit. If you are not sure which light you have the number might be on the housing somewhere, likely the back, but not on the lens. That is a different number. If there are no part numbers on the light housing then I would need to know the dimensions of the light you have to determine if this or another lens will fit.

  • Recommended 4 inch by 2 inch Clearance Light for Trailer
