Optronics MC32 Series Incandescent Marker Clearance Light Dimensions

P2-Rated Lights

Diagram of light spread for P2 rated light

A P2-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.

still working as expected!

Excellent product at an affordable price. I also appreciate the follow up after the purchase from trailer staff.



by:

The part was an exact fit for the original. Good quality, price was ok. I had no problems with installation.



by:

Needed new lenses for existing RV marker lights. Product arrived in good condition.



by:

It is a perfect match to the marker light i have to replace. You guys are great.

Items arrive broken because they put them loose in the same box with spring hangers!



by:

Fit perfectly in the spot where the old one was. Easy replacement



by:

Good replacement, same as what I have.



by:

These lights are really good for the price! (I ordered 16)
They aren't cheap feeling or flimsy.
They feel sturdy, durable and they look quality.
The wires are the correct gauge and the light bulb is in a rubber grommet for weather sealing.
The light is sealed very well and it takes some effort to remove the lens cover.
The lens is thick and the color is true. The reflector is bright.
I was genuinely impressed with lights especially for the cost.
These will be replacing older side marker and clearance lights on my older 1985 Sunstream motor home.
My lights are faded, some broken, mostly leaking and more costly to replace than what they are worth.
These MC32RB and the Amber version lights will look great!
Slightly different style, same size and better looking and better quality than the originals.
Very happy with lights and etrailer.
Will be ordering more items.
Thanks.
G.

It was hard to find this market light, trailer comes thru again!



by:

I purchased red and amber lights to replace the faded and broken ones on my travel trailer. Camping World wasn't able to help me. Found you all while searching the internet. Great produce. Great price. Better than the originals. The screws that secure the lights to the trailer are protected from the weather (they are under the removable lens. Easy to install. Ended up replacing all eleven lights.



by:

older trailer was put on replaced exactly as broken one



by:

Easy to order and arrived quickly! It was a perfect match!

This product was an exact replacement for the o e installed on my RV. Installation was a snap!

The light is still working well and has not faded or cracked. Very happy with it.



by:

This is a standard size clearance light. It should work for most customers. It was a replacement for a light that just had two wires coming out the back. This product has a gromet that extends out the back. It did not fit my entry hole. I modified the geometry to make work.



by:

Perfect fit and the color needed. Installing was a breeze.



by:

This was my 2nd time ordering from e-trailer! They are great to deal with. Parts are 100% factory match for my camper. Always fast shipping too!



by:

Fit perfectly



by:

It works as designed. I had to use a black marker on the white edge to make it match the other marker lights on my trailer.



by:

This is a very nice looking and well made light. I needed to modify the two wire configuration to a single wire as I could not run a ground wire. It was a simple modification. I have included a series of pictures to illustrate. I am very happy with the price and quality.



by:

I highly recommend this product if you need to replace a broken light housing or cover. You won't be disappointed.



by:

The marker lights work excellent and will try not to run into my fence again!



by:

Great product, great price, fast shipping! It doesn't get any better, and I buy a lot of stuff on the web. I don't usually write reviews but these guys are so good I had to put in a good word.
Highly recommended!



by:

let there be light, worked great.



by:

Fabulous service. I called on a Sunday, of all days. Was not expecting them to answer. They did. Agent was super friendly and nice. Took my order in a like 10 min. All done. Four days later I got my item. Will do business with them again.

  • Need Replacement Lenses for 2003 Coleman Trailer
    From the dimensions that were given and the picture that you provided, it looks as though the Replacement Red Lens, # A32RB, and Replacement Amber Lens, # A32AB, would work for you. These lenses measure 4 inches long, 2 inches wide, and 1/2 inch high. The number/letter combo, P2 A 99, that you mention is more than likely the SAE, Society of Automotive Engineers, number. The SAE number is not the part number of the light, it is just a number on the lens that means that lens has passed SAE...

  • Replacement Red and Amber Clearance Lights to Use In Place of Kaper II 1A-S-20 Lights
    The 1A-S-20 lights are Kaper II lights that we do not carry but they should have the same 4 inch by 2 inch measurement as # MC32RB and # MC32AB. The replacement red lens is # A32RB and for the amber light the replacement lens is # A32AB. I have linked video reviews of both lights for you.

  • Recommended Marker Light For Fenders On 1999 Pace Worksport
    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. I see two different colors online, so I'll give you an option for an amber light and a red light. 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. It is a surface mount with a twist-in...

  • Can Optronics Light # MC32AB Be Installed on Trailer that Grounds Lights Through Mounting Hardware
    Sounds like you bought the # MC32AB and the # MC32RB to replace what you have on your trailer. This is the only style of light we offer in that size. It sounds like your trailer may ground it's light assemblies through the mounting hardware. Which in this case would mean that you would only need to run the ground wire of this light to the mounting hardware.

  • Availability of Replacement Amber and Red Lenses for Optronics Trailer Lights # MC32RB
    We do offer both red and amber replacement lenses for the Optronics Rectangular Trailer Clearance Side Marker Light # MC32RB. The red lens is part # A32RB and the amber lens is part # A32AB. These lenses measure 4-inches x 2-inches x 1/2-inch and they snap into place without hardware. I have included a video on this trailer light.

  • Clearance Trailer Lights With Replaceable Lens Recommendation
    We do have clearance lights that may work for you. The clearance lights we offer come in amber or red and we have either 1 or 2 bulb units. You mentioned you like the 2-bulb feature on some clearance lights. I recommend part # MC66RB. This light comes with 2 incandescent bulbs and has a red lens. The amber version of this light is part # MC66AB. Both of these lights use the replacement bulbs, part # A194B. These are push-in bulbs. The replacement lens for the red light assembly is part...

  • Replacement Amber Light for a Carry On Trailer
    We should have a good replacement for your Optronics light, but I was unable to find anything using the SAE number provided, unfortunately. With that said, you will need to measure your current light to find the direct replacement. Something like the Optronics Trailer Clearance or Side Marker Light w/ Reflex Reflector # MC32AB will measure 4 inches long, 2 inches tall, and 1-1/8 inches deep (diagram below). As a side note, a lot of Optronics' lights have part numbers printed on the back...

  • Replacement Lens for Optronics MC32 and MCL32 Series Lights
    You aren't missing anything, no; the Replacement Red Lens for Optronics MC32RB and MCL32RB Trailer Lights # A32RB is exactly what you need as a replacement lens for either the Optronics Trailer Clearance or Side Marker Light # MC32RB (Incandescent) or # MCL32RB (LED). This is the correct lens, though it will snap on so it will be somewhat tight; using a smidgen of force will snap it on.

  • Are Replacement Lenses Available for Bargman Series #178 Lights
    I spoke with my contact at Bargman and the lenses on the Series #178 lights are not meant to be removed. Instead they make their lights very economically priced so that the entire unit can be replaced. Replacement lenses for these Bargman lights are not available. If you would like to go with a unit that has replacement lenses available, the Optronics Rectangular Trailer Side Marker Light, # MC32AB and # MC32RB, would be a great option. These are a customer favorite! Replacement lenses...

  • Looking for Replacement Lens for Fruehauf # LCE-8750 Clearance Lamp
    We don't offer a replacement lens for a Fruehauf LCE-8750, but we do offer a equivalent lamp from Optronics, part # MCL32RB for the LED version or # MC32RB for the incandescent. We do offer a replacement lens for the incandescent version, which is part # A32RB. I can state with certainty that the replacement lens will fit the Optronics lamp, but since they're different manufacturers, I can't guarantee that the replacement lens will fit your existing LCE-8750 lamp. You can gamble that...

  • Recommended Clearance Marker Lights Compatible with 1999 Coachmen Viking Pop-Up Camping Trailer
    The Rectangular Trailer Clearance, Side Marker Light with Reflector - Red # MC32RB will work on your 1999 Coachmen Viking Pop-Up Camper for the rear side clearance light. If you want the front clearance marker as well, you will want # MC32AB. Both of these lights are 4 x 2 inches and have mounting holes 3 inches on center.

  • Does the Snap On Reflex Lens on the Bargman 99 Series Trailer Light # 3499001 Qualify as a Reflector
    We do carry clearance and side marker lights that also qualify as reflectors, however, I spoke with my contact at Bargman and the Bargman 99 Series Trailer Clearance and Side Marker Light, # 3499001, does not qualify as a reflector. Instead, I would recommend the Optronics Trailer Clearance and Side Marker Light, # MC32RB. This light is DOT compliant as both a reflector and a clearance or side marker light. I have attached a review video for you to check out.

  • Replacement Clearance Light Recommendation for 1999 Sand Piper Travel Trailer
    I looked up pictures of your 1999 Sand Piper travel trailer online and from what I could tell the clearance light part # MC32RB that you referenced is an exact match and would work well. This is one of the most common clearance light styles found on RVs so it's very common that this is the correct replacement for trailers.

  • Do the Clearance Lights MC32RB and MC32AB have Gaskets
    Both the # MC32RB and the # MC32AB do not have foam gaskets between the lens and the base. It is unlikely but possible that your current trailer lights had lenses that were once color and have now faded to being totally clear.

  • Recommendation for Durable LED Clearance Light for Utility Trailer
    We do have a large selection of LED clearance lights available that closely match the dimensions you provided for your existing assemblies. I have attached a couple links that will take you directly to this selection that you can look through. In general, LED tail lights will indeed be a bit more durable than standard incandescents just because they use diodes instead of the more fragile bulbs and filaments inside the assembly. They will certainly be able to handle more shock and vibration...

  • Replacement Lens for Optronics MC32RB Clearance/Marker Light

  • Replacement Red Lens for Clearance Light on 2015 Thor Ace
    I was unable to locate the exact model clearance light that is installed on your 2015 Thor Ace, however based on the pictures I found, the lights look very similar to the Optronics # MC32RB, for which the replacement lens is part # A32RB. This light measures 4 inches long and 2 inches wide. You can compare this to the dimensions on your existing lens to see if it might work as a replacement. Otherwise, I recommend seeing if you can find any part or manufacturer information on the light...

  • Does The Optronics Trailer Clearance Light # MC32RB Come With Bulbs
    Hey David, The Optronics Trailer Clearance or Side Marker Light w/ Reflector # MC32RB comes with a 194 bulb # A194B. The mounting holes are 3" apart from center to center, but with this being a surface mount you can just use on hole and fill in the other hole with some sealant and shoot the screw in making a new hole.

  • How Does the Replacement Lens A32RB Fit on the MC32RB
    The base of the Optronics Trailer Clearance or Side Marker Light w/ Reflector - Incandescent - White Base - Red Lens # MC32RB, which is what the # A32RB is designed for, will have clips on it to assist with keeping it secure. If your light does not have the clips on it, but this lens still fits, you can use some double sided tape around the outside of the bracket to help keep this secure. I wouldn't suggest using glue of any type because if the lens were ever to break again, you likely...

    I may have another product that will work for you, but the Bargman Trailer Clearance or Side Marker Light # 30-17-814 does not have replacements lenses available, unfortunately. With that being said, the Optronics Trailer Clearance or Side Marker Light # MC32RB will be a very close alternate to the Bargman # 30-17-814, but does have the replacement lens # A32RB available.

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...

    Yes, the bulbs do come with the Optronics Lights # ST40RB, # MC32RB and # MC32AB.
