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.

This is a good quality light, water tight and worked well. It has been on the trailer for over a year now and still has no issues. The lens can interchange on other similar bases, but if the base is old and damaged like mine was, this is a great replacement.

Easy replacement for my Thor Hurricane back lights.

Oh no! I am sorry the wrong light was sent out. We will be in contact with you so that we can have the incorrect light returned.

Awesome service great parts fast shipping thanks again.



by:

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



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.

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



by:

Katie did a perfect job getting me the right parts that fit and work!



by:

Easy install!



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.

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.

Great fast service and product!

They’re exactly what we were looking for ! With having an older RV I was so excited to find this site . They are so helpful too . Easy to contact and respond fast. Very friendly. I definitely recommend anything you need they will try their best to help you !



by:

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



by:

Excellent service



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:

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



by:

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



by:

Good replacement, same as what I have.



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: 01/02/2024

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



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:

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



by:

You seem to always have what I need.

See what our Experts say about this Optronics Trailer Lights

  • Replacement For A SAE-A-P2-72 Trailer Light
    We do offer the Optronics trailer light # MC32RB for red and # MC32AB for amber. These lights will be extremely similar to the # MCL31RB that you mentioned, but they are a bit more square on the ends. The mounting holes on the # MC32RB are 3" apart on center which should be fairly standard. This # MC32AB and # MC32RB appear to be what you are looking for.

  • Replacing The Light And/Or Lens On A Bargman 34-59-010 LED Light
    I do have an option for you but unfortunately the Bargman lens 34-59-010 you are looking for is no longer available. The lights themselves are also not available. I can offer you a virtually identical light in the Optronics # MCL32RB. This is a 4" long x 2" tall x 1' deep red LED clearance or side marker light, and will be virtually identical to your Bargman LED lights.

  • Replacement Clearance Lights Options For a 1991 Newmar American Star 25RK 5TH Wheel RV Camper
    Yes, we do have these lights available in both incandescent or LED. The lights will all have a white base and the lights have an overall size of 4" long by 2" wide and 1" deep. Incandescent Amber Lens # MC32AB Incandescent Red Lens # MC32RB LED Amber Lens # MCL32AB LED Red Lens # MCL32RB Amber Replacement Lens # A32AB Red Replacement Lens # A32RB I recommend getting a couple spare lenses in the event one of them becomes damaged while driving.

  • 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 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.

  • Correct Replacement Light for Trailer Light Base Part # 1A-S-9
    If the base of your marker light, # 1A-S-9, is part of the Kaper II Trailer Light # 1A-S-100A, then the correct replacement base is the Optronics Rectangular Marker Light, # MC32RB. This marker light comes with a red lens and the replacement red lenses are # A32RB. The replacement lenses # A32AB that you referenced are the amber replacement lenses.

  • Clearance Light Recommendation for a Kaper II 1A-S-20R
    You should be able to get the Optronics Trailer Lights # MC32RB that you referenced to fit on your trailer one way or the other. The mounting holes for this light are 3 inches apart. If the mounting studs of your trailer are also 3 inches apart this light would bolt right up. I attached a review video for this light for you to check out as well.

  • 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...

  • LED Replacements for Optronics Rectangular Trailer Clearance Lamp MC32RB
    We do not have an exact LED replacement for the incandescent side marker lamp you mentioned, part # MC32RB, but we have an alternative that is very close. Part # MCL31RB (red lens) and part # MCL31AB (amber lens) are shaped a bit differently than the lamp you referenced. They are also about an 1/8 of an inch wider and thinner in depth. The important dimension, the distance between the mounting holes, is still three inches, so you will be able to use the existing holes. If you click on...

  • 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.

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...

  • 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...

    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 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.
