Video Transcript for Review of Optronics Replacement Parts - Trailer Lights Replacement Lens - A32RB

Randy: Hey guys, it's Randy here at Now, we often get questions from our customers about replacement parts for their camper trailer, enclosed trailer, and this is going to be a very, very popular one. This is going to be the replacement for your standard four by two rectangular light. Now, they come from a lot of manufacturers. This one is from Optronics, specifically. It's designed to fit the MCL32RB and the MC32RB.

That L designates it's an LED light. Without the L, it's just a standard incandescent, but this will fit a lot of the other two by four rectangular bases as well. This is an acrylic lens, so it's going to be durable and I like Optronics products. They always seem to be really, really dependable, really reliable, but a lot of times with these lights you're going to get a lot of sun fade.You're going to get some of the hazing over the top, so whether you're current one, you ran into it with something and broke it or you're just trying to refresh the look of a trailer, I think this is going to be ideal. It does have, you can kind of see, the reflector that's built in there.

So even when we're not putting power through the light, as headlights headed, it is gonna shine. It'll be bright enough for people to recognize it and not accidentally bump into your trailer or something like that. Now it pops right onto the original base. So this is going to save you the work of taking off the old base, making your wiring connections and putting a new base on. Now of course, we do have the full assembly in those two part numbers I mentioned earlier, if you do want to replace the base, but this is going to be a little bit quicker option for you if the light is still working fine and we just need to get it covered and protected.Now to give you a look here, you'll notice that the light from one side to the other is right at four inches.

Widthwise, at it's thickest point there, right at two inches. So your base for this to clip on should be slightly narrower than that. We're going to have three little tabs here at the bottom and three here on the top. That's what's going to hold onto that base. Usually the base has a little rounded edge with a little low spot in it where this is going to clip right on.

Now, over time, with your older ones, these can get brittle. People sometimes, when they're putting them on the bases will break, so just be careful with it as you're putting it on, but this can be a great way, like I said, to either update the look or get your replacement on there without having to go through the additional hassle of the wiring and the base installation.

Replacement Red Lens for Optronics MC32RB and MCL32RB Trailer Lights - A32RB

Average Customer Rating:  4.9 out of 5 stars   (400 Customer Reviews)

Snap-on red lens replaces the lens for your Optronics clearance or side marker light. Fits MC32 and MCL32 series lights.


It's red translucent plastic of some sort. Light shines through as it should. Fits snuggly on the light fixture it was made for. I have not had to give it any thought since! I can't give it an excellent, because it would have to do something above and beyond what I have written to warrant that rating. All in all I am a happy camper!


I had a hard finding replacement lens for my camper, local auto parts stores all stocked other style lights and offered no replacement lens ! With a couple of clicks, exactly what I needed were n their way ! Tracking was easy through the emails ! Will definitely use again and just spoke with my sis about her trailer needs and referred her to as well ! ,,,, thanks George !


The lenses were exact replacement for those lost off of our Rockwood ESP 1910 during our recent trip to Florida. The sales rep was very helpful in assisting placement of order. I was thinking we would have to replace entire LED fixtures which are backordered to June, but he located these. We had them in 6 days, were installed, & saved $$ also. We’ll done guys!!! I definitely will be using etrailer in the future!


When my lens got hit and broke recently, I expected to call the RV manufacturer and be told the part is either not available, or cost a ridiculous amount. Instead, I noticed the Optronics name on the lens, searched the Net and found them in OK and found the part number from their catalog and a visual match. Then I searched the Net for that part number and found it at I was pleasantly surprised that the price was very reasonable, so I bought several. Part came today, is a perfect match and snapped right in place. Problem solved.

A year later, still looks new.
Ted - 11/03/2021


Exactly what hat I ordered and arrived in a timely manner. Great service from Thank you all. Did I mention great prices as well!


everything was just thrown together in a box-tail light fixtures-several plastic lenses-2 metal jack handles-plastic and jack handles do not mix well together-very poor packaging

I will have our customer service team reach out to you.
-- Etrailer Expert Jenny N - 11/30/2021


Our cover was accidentally broken when coming out of storage. I looked up the number of the light on the internet and found your site. I ordered this and it came quickly and was well packaged. I went right out and popped it on to our Sport Trek Travel Trailer. Perfect fit! Thank you! I will be back to order more!


This is only one of my purchases. All items arrived on or ahead of time and are all of excellent quality. Will be a future customer for sure.


Very quick delivery and excellent service and price. Fit our Optronics marker light perfectly! I included a picture of the assembly because this was the only number on the unit.


Thanks for the lens covers. Perfect fi t.


just as described & fast shipping


Direct replacement. No issues.

Still ok.
Michael - 03/14/2022


Fit my RV, Sandpiper by Forest River, perfectly. Still looks good one year later.


Ordered lens covers to replace old brittle lenses, can't beat the price, and looks great also, thumbs up!


Fit snugly and stay on...bright and sharp. Had to change all of the faded ones to pass new Texas trailer inspection. Hope the color holds up in the sun. Good price and delivered promptly. Thanks!


Perfect fit. Fast delivery. Great service as always.


Fit perfectly and was a perfect match for the one on the passenger side and Lori B was very helpful and helped me to make sure I got the right part

Still working great a year later
Richard - 09/25/2021


It fit as exactly like the original. Th anks

It worked great
Bart - 04/25/2022


Outstanding service, my order was mixed up (My fault) I called and received quick and outstanding service. The order was fixed and received two days later. Will use again and again to maintenance my Rig.


The red lenses fit and stay put just as well as the orange lenses. Thanks E-trailer!


Acidentaly smashed the light cover when backing up our camper in the garage. I told my husband we should be able to buy just the cover not the whole assembly as he feared. I knew where to go; Yep, ordered just the light cover, came in 2 days and fit perfectly!!! Thank you etrailer!

Heather G - 06/28/2020


My reasons for buying these are rather unique- I store my trailer on wheel dollies, in the garage.

More than once, after a long trip and I'm tired, I have accidentally pushed the trailer beyond it's normal storage space and right into the corner of my workbench. Now on one hand I'm grateful that the damage only occurs to my marker light and not something more expensive to repair. On the other hand, I need to keep at least three replacement lenses stored in my workbench now, because I'm clumsy and this happens a few times a year.

Great quality replacement legs though. I'm almost due to replenish my stock of them soon.


Perfect fit


Exact match to what the factory had installed and fit perfectly!! Was shipped very fast and arrived earlier than expected! Lens covers were brand new and came packaged in a big envelope and should of been protected better. Lens were floating freely and could have been crushed, cracked or broken in to pieces. That is my only complaint and the reason I did not give 5 stars.

One year has gone by and lenses have held up perfectly! No issues and still look brand new. Highly recommend.
Thomas - 06/01/2020


This item was exactly what we needed. Pictures and specifications allowed for accurate selection to order. Part fit perfectly. Service was spot on; order confirmation, updates, mailing and receiving was done well. Received in very reasonable time. Recommend these guys and will use again.

Still going strong.

  • 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.

  • 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...

  • Replacement Taillight Lens Recommendation for a 2001 Dutchman Classic
    If the light on your 2001 Dutchman Classic looks like the part # MC32RB then yes, the part # A32RB would be the correct replacement lens to use. Nearly all trailer taillight manufacturers will use the same designs and the lenses will interchange. So take a good look at the # MC32RB, and if it matches what you have then the # A32RB would work for you.

  • Trailer Light Replacement Lens for Light Marked SAE-A-P2-DOT-02
    Normally the SAE number isn't a reliable way to pick out replacement lenses, but we know that the # A32RB is the correct replacement for a lens marked SAE-A-P2-DOT-02 like what you have. For an all new assembly you'd want the part # MC32RB.

  • Replacement Lens Recommendation for Trailer Clearance Light with 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 # A32RB which measures 4 inch by 2 inch.

    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...

  • Replacement Lens Cover For Optronics MC32RB And SAE-A-P2-DOT-02
    I believe you are referring to the Optronics SAE-A-P2-DOT-02 which I can see you were looking at. If so, then Replacement Red Lens for Optronics MC32RB and MCL32RB Trailer Lights # A32RB is the correct replacement lens. If you end up needing the whole assembly then you can find that here: # MC32RB.

  • 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.

    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.

    The Replacement Red Lens for MC32RB Trailer Lights # A32RB is specifically designed to fit the Rectangular Trailer Clearance, Side Marker Light with Reflector # MC32RB from Optronics so I don't think it will fit your light. The P2A 01 number that you gave me relates to the SAE number and not the product number so we typically wouldn't know what your dimensions are. We have had a number of customers ask about the P2A 01 light lens though and the Replacement Red Lens # A44RB has actually...
