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.

Ask the Experts about this Optronics 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, # MCL51CAK, # MCL65CAB, # AL91CAB, # MCL17CAB, # 00212336P,...

  • Replacement Trailer Taillight Recommendation for Reflect o Lite 400
    Your exact light isn't available anymore but we have found that the # MC32AB and the # MC32RB are very similar to what you are looking for and will work well.

  • 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...

  • 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
    The SAE number of a trailer light isn't always the best way to pick out a replacement light since that isn't a part number. But most likely you are looking for a # MC32RB which measures 4 inch by 2 inch. If not, check out the link I attached that has all of the trailer lights we offer.

  • Replacement for Reflect-O-Lite 400
    The Reflect-O-Lite line has been discontinued for quite some time so replacements are no longer available. However, the Trailer Clearance or Side Marker Light w/ Reflex Reflector part # MC32AB is a very similar option that will work well in its place. In regards to installation, all you will need to do is mount the base with a screws part # 1131832 and then match up the wires with butt connectors part # DW05744-5.

  • 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 Side Marker Light that has SAE AP2 01 On the Lens
    If your original light is 4" L x 2" W x 1-1/8" D then Optronics light # MC32AB will fit in its place. If you have different dimensions let me know what they are and I can see if we have anything that is a match.

  • Amber Lens Replacement for Thor Class C Motorhome with AEP2 58-59 Number
    The number you listed isn't exactly a part number so it's hard to cross reference it but we've seen customers in the past ask about it and it ended up being a light like the part # MC32AB. Which then for a replacement lens you'd want the part # A32AB. If what you have looks like this light then this is the correct lens. If not, send me a picture of what you have and I'll most likely be able to track it down.

  • Replacement Light Recommendation for SAE AP2-80
    Based on the picture you sent in it looks like you would need a part # MC48AB and # MC48RB as a replacement. This measures 3-29/32" L x 1-27/32" W x 1-1/32" D so you would need to compare that to the light you have. The mounting holes are 3-3/8 inches apart on center.

  • 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...

  • How to Install an Amber Turn and Parking Light on a Trailer with Combined Brake and Turn Signals
    Many people inquire about wiring a trailer in the way you describe, and it is possible, but you will need to use a vehicle to vehicle taillight converter, part # 118158, to accomplish this. The converter will be wired inline on the trailer wiring and will break out the turn and brake circuits. I attached a drawing that shows how I would go about wiring this converter on a simple 4 wire trailer. You would just need to cap off the red wire on the output side of the converter and tie that...

  • 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....

  • 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.

  • Does The Optronics Trailer Clearance Light # MC32AB Include a Bulb
    The item you selected, Optronics Trailer Clearance Light, part # MC32AB, includes a # 194 size bulb already installed. In the future, if you need to replace the bulb, the lens is removable. For a replacement bulb we have the Replacement Side Marker Light Bulb # 194, part # A194B. For a replacement lens, we have the Replacement Amber Lens, part # A32AB.

  • What Adhesive To Use When Replacing Clearance Light on 1987 Itasca Motor Home
    I would recommend using a sealer so there is minimal chance of moisture seeping behind the light fixture. I recommend Fastenal TremPro 644 Silicone Sealant # 0160297. It creates a waterproof seal at seams between joined parts and adheres to nearly anything. Be sure to remove any old silicone or adhesive to the area prior to the application of the new silicone.

  • Does Wiring Polarity Matter for Installing Optronics Clearance or Side Marker Light MC32AB
    Yes, the Optronics Trailer Clearance or Side Marker Light # MC32AB can be wired with either of its two black wires used for ground or for power. Since this is a single-function/single-bulb light it does not matter which is which. For a replacement incandescent bulb for this light you can use part # A194B which is a 194-type standard bulb.

  • Is a LED Upgrade Available to Replace the Rectangular Trailer Side Marker Light # MC32AB
    Optronics does make a LED light that is close to the same size as the, # MC32AB. Check out the Sealed, Rectangular LED Trailer Clearance and Side Marker Light, # MCL49AB. I have also provided a link to a video review showing this light in action. If this Light is not what you are looking for, I have provided a link to all of the LED, rectangle, amber clearance lights that we have at this time.

  • Trailer Replacement Lens Availability
    We have several replacement lenses for trailer lights that could potentially work for you, but unfortunately the numbers you listed aren't part numbers so they don't cross reference with anything. I did attach a link to the right that shows all of the replacement light lenses we offer. My recommendation would be to use the filters on the left side of the page to narrow down what you have and then once you find a lens that looks similar to yours compare the measurements to what you have.

  • How to Use an Amber Turn Signal Parking Light on a Trailer with Combined Taillights
    What you are going to need to install the Trailer Turn Signal and Parking Light # MC32AB that you referenced is a Vehicle to Vehicle Taillight Converter # 118158. This product will wire in on the trailer wiring and will split your tail light circuitry so that the blinker and brake light circuits will be separate. Here is how it will wire in. You will run the ground wire from your trailer 4-way to white wire of the box, the left turn/stop wire to the yellow wire and the right turn/stop...

  • Recommended 4 inch by 2 inch Clearance Light for Trailer
    SAE numbers aren't reliable ways to track down trailer lights unfortunately. But if you can get me a picture of the light I am sure I can find it. A very common light that matches the 2 inch by 4 inch dimension is the part # MC32AB.

    I don't have the specs for your specific light as manufacturers constantly change lights, but I can make a recommendation for you to replace what was ripped out.

For an amber light, I recommend the Trailer Clearance or Side Marker Light w/ Reflex Reflector - Rectangle - Amber Lens - White Base, # MC32AB. This light is 4 long x 2 tall x 1-1/8 inches deep.

  • What Size Hole Needs to be Drilled to Mount Optronics Trailer Clearance Light # MC32AB
    I went out to the warehouse to take a measurement of the Optronics trailer light # MC32AB. On the back where the wiring is the grommet width is 0.65 inches so that is the size hole you will need. You can use an 11/16 inch drill bit which will provide a slightly larger hole. I also made a video for you sharing this information.

    If a traditional converter is not enough to power the all of the lights on your trailer (usually if there are too many lights, some of them might rapidly blink or not power on or be very dim), you would need a powered converter like the Upgraded Circuit Protected Modulite, # 119179KIT, that has a separate connection to the vehicle battery to power the lights. The power would then come from the battery and not from the vehicle wiring or the converter. That direct connection to the battery...

    Since there are so many different lights that are used on trailers it is nearly impossible to track down what lights are used on a specific model. You may be able to find the manufacturer and model number on the base of the light and that would help us research and see if we can find a replacement lens. Another way is if you measure the lens and let me know as well as how it is attached to the light. A third option is to replace the light. A lot of customers choose this option...

    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.

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...
