Video Transcript for Review of Optronics Red Trailer Light Lens - A44RB

Michael: Hi, there. I'm Michael with Today, we're going to take a quick look at the Optronics red trailer light lens. This is going to replace a damaged or lost lens to help complete the look on your trailer. Give you a nice finished look and to make sure that you're getting that nice red light there on your trailer. This is a replacement for the MC 44 series and BA 44 series lights, but it may also work for others as well.

This lens is right at, I'm going to call it four inches exactly in width. Our height, we're right at one and a half inches. And then the thickness there, not that it's going to stick out from our trailer, I'm going to call it about right at a half inch in total height or thickness depending on how you look at it.So if you are needing a replacement red lens for your trailer, this is going to be a great option for you. It is Department of Transportation approved and SAE certified. So it's going to hold up well, do a good job for you, and make sure that you are nice and visible as you're going down the road.

That's going to complete our look for today. Again, I'm Michael with Thanks for watching.

Replacement Red Lens for MC44 Series and BA44 Series Trailer Lights - A44RB

Average Customer Rating:  4.9 out of 5 stars   (239 Customer Reviews)


Hail storm took out some clearance lights on my 2017 Minnie Winnie. Had a little difficulty locating them on line. Until I found the e trailer site. They had the exact oem match. Shipped in a timely manner and they kept me updated through every phase from order through delivery. Fast efficient and the correct item at a fair price.


Product was direct replacement on my 2015 Livin Lite 16TBS.

Only complaint and its minor. Once the package was delivered, whitch was at the post office and not our home address. (This happens to people living in rural areas). At this point I couldn't track the package as I didn't have carrier or tracking information.


I have a Pace 6x10 enclosed with a ramp. When I bought it the clearance lights on the fenders really didn't work. They were also missing 2 amber and 1 red lens coverso. I fixed the ground issue on both sides and etrailer hooked me up with the lens covets. Popped them on problem. Exactly what I needed.


I accidentally cracked the red side marker lens at the rear of the trailer. Damage was enough where moisture could affect the light. This lens fit perfectly with a snugger fit than the original. No moisture will get to the wiring now. I ordered two so I would have a spare.


I was concerned that I could find lenses that I had broke and thought I have to replace all the lights. I was wrong. I found the replacement lenses easily on etrailer, ordered them and within a few days they’re installed.
Thank you!!


Overall a nice product; however, one was DOA (etrailer customer service took care of that easily); lens is easy to crack so be super careful when opening it to install. They aren't as bright as some I've seen on Amazon for a lower price but wasn't sure of the quality. I can count on to stand behind their product.


The lens is a perfect fit and the price is the best I found on-line. Add to that your great service and I have to believe the E on etrailer stands for Exceptional.
Note: I did some research on-line to find out that the A44RB was an exact match for the Glo-Brite 117A & 118R. Searching the A44RB is how I came across ETrailer. You might want to include that information on your site so anyone searching the 117A or 118R will find you.
Thanks again!


I got this to replace the lens on my 2006 Winnebago sightseer. It was originally a glo brite 118a/117r
As stated on this site this lens fits as a perfect replacement.

The lens is still going strong after a year on the road! Would not hesitate to buy more...
Bryan S - 12/20/2017


Installation of these replacement clearance lights pretty simple! They were exactly what I wanted! Thank y’all


Perfect fit for my Winnebago chalet. Are use the trailer for all my RV needs they seem to have it all


We weren't impressed with the fact that the bulbs we ordered were just thrown in the envelope with no protection from the other contents or from the USPS. We ship regularly as part of our current business as well as my former business and the fact that these bulbs were intact is nothing short of a minor miracle. I had decided to wait to post a full review until we ordered the correct lenses (we ordered red by mistake, the orange ones have just arrived and we'll be installing them today or tomorrow).


The correct replacement lens for my trailer. Perfectly satisfied with the product.


The lens fit perfectly


Overall good product. Not as bright as some I've seen online at a lower price but worth the purchase.


Speedy service, well packed and was exactly as described. Fit perfectly.


I am very happy with these lightcovers. They fit perfectly. Most of all I am happy to find them on etrailer as the dealer couldn’t get them and wanted to sell me all new fixtures. Thanks etrailer!


I was unable to find this product any place in my area. I went on line and found it at etrailer. This is the second item I purchased from them and I had it within days. They are a great company to work with.


Thank you guys , I will be shopping here again !


Perfect fit for my motor home

Excellent replacements recommend to many RVers
Ed - 08/26/2021


Exact match, fits perfect.


As usual etrailer is fast and provides the product that works as ordered.


Lost a taillight cover on my cargo trailer. Found the replacement at etrailer, ordered it, received it in a few days, popped it on & it's good to go!

Still good to go!
Edmund Z - 07/31/2019


Not just for trailers!!
I somehow
lost a lens cap from my brand new, Leisure Travel RV. I thought I'd be in for a hassle finding a replacement but, based solely on the number embossed on the lens, I found this site and ordered the part. Perfect fit on existing base, exact match to other markers on the vehicle. Impressively low price, very quick delivery and meaningful follow up. Thanks for a great service!


Worked just perfect! We were glad that we didn't have to replace the whole light. Came in just a short period of time. Thankful that I didn't have to run around looking for just the cover.

Still in great condition

  • Replacement Red Lens for Trailer Clearance Light with SAE P 2A 01 On the Lens
    The numbers on the lens indicate how the light is rated. LED clearance light # MCL44RB does have the same numbers on the lens meaning it carries the same rating. It is likely going to work for you but to be sure take a look at the measurements and compare them to your existing light to make sure they are compatible. Light # MCL44RB is 4 inches long, 1-1/2 inches wide, and 15/15 inches deep. I have linked a video review of this light for you. If you just want the lens then it is # A44RB.

    The entire lamp assembly that goes with the # A44RB lens you specified is part # MC44RB.

  • Replacement Optronics SAE P2A 01 DOT Trailer Light Lens
    The SAE number you provided in your question isn't always the most accurate way to determine a correct replacement assembly. This is simply because it does not refer to the actual light part number, but to various safety guidelines that it meets. However, based on previous customer inquiries with this particular SAE number, the correct replacement might be the Optronics Replacement Red Lens # A44RB. This lens measures 4 inches wide and 1-1/2 inches in height. I recommend verifying these...

  • Replacement Lights or Lens for Motorhome Based on Measurement Not SAE Number
    We don't have anything that is 16 inches long by 3 inches. I've linked the pages to our replacement options as well as our lens options. The SAE number helps with codes so I know it is a rear side marker light with turn signal and you have already helped with the color. Unfortunately the SAE number won't give more information to help replace the lens and I've attached an article to help with those codes. You most likely will need to choose a replacement option from our amber trailer...

  • Replacement Trailer Light Lens with SAE P2A 01 DOT on Front of Lens
    The SAE number isn't the best way to pick out replacement lenses for trailer taillights since that isn't actually a part number. However, I did find a replacement lens with SAE P2A 01 DOT on the front of it. Check out the part # A44RB. If this looks like what you have and matches the dimensions of your lens then it would be the correct lens to use. This lens is 4" W x 1-1/2" H. If you need this lens in amber you would want # A44AB.

  • Amber Trailer Light Lens To Replace Glo-Brite 118A Trailer Light Lens
    Based on my research, the Glo-Brite 118A amber light is approximately 4 inches long by 1-1/2 inches wide. I spoke with my contact at Optronicc who confirmed that their Replacement Amber Lens # A44AB will fit the Glo-Brite 118A trailer light. I found the Glo-Brite 117R light to be a red taillight of the same 4 inches by 1-1/2 inches. For a replacement lens for the red light you could use part # A44RB.

  • Replacement Red Lens for Optronics MCL40RB

  • Availability of Optronics A44RB Replacement Clearance/Marker Lamp Lens in Amber
    The trailer lamp manufacturers refer to the orange lens as being amber in color, which likely explains why you've had difficulty finding the proper lens. You'll need the amber version of the # A44RB which is part # A44AB. The replacement lens measures 4 x 1-1/2 inches as shown in the photo I've edited for you.

  • Replacement Lenses and Light Assemblies for Glo-Brite 118A/117R
    The Glo-Brite 118A is the amber light and for the lens you need # A44AB while the light assemblies are the Optronics # MC44AB. For a Glo-Brite 117R, which is the red light, you need replacement lens # A44RB and light # MC44RB. We do not carry Glo-Brite products so while Optronics has previously confirmed for us the lenses will snap into the Glo-Brite light housing the light assemblies themselves are 2-wire lights and not 3-wire lights like Glo-Brite.

  • Replacement Lenses and Lights for Glo-Brite 118A/117R
    For your Glo-Brite 118A amber light the replacement lens that will fit is the Optronics # A44AB; the lights themselves are the Optronics # MC44AB. The Glo-Brite 117R can use replacement lens # A44RB while the light is # MC44RB. I've added links to video reviews of the lights for you to check out as well.

  • Replacement Lenses for MCL40/44 Series Optronics Lights in Red and Amber
    The Replacement Red Lens for MC44 Series and BA44 Series Trailer Lights # A44RB is the 4 inch by 1-1/2 inch replacement for the # MCL40RB light. If you need the amber replacement lens that is # A44AB. These lenses will fit the MCK40/44 series lights from Optronics and I've confirmed this fit on the MCL40AB light you referenced.

  • Replacement Lens for Bargman 99 Series Clearance Light on a 1999 Pace-American Trailer
    It is possible that the Bargman Replacement Lens for 99 Series Clearance Lights, # 3499010, is the correct replacement. There are different designs in the 99 series lights. The 3499010 lens is a trapezoid shape. Another possible fit would be the Replacement Red Lens for MC44 Series and BA44 Series Trailer Lights, # A44RB. This lens has a semi-circle shape. The 3499010, that you have referenced measures 4-1/8 inches long, 1-1/4 inches tall, and 9/16 inches deep. The best way to determine...

  • How to Determine if Replacement Lens A44AB or A44RB Will Fit
    I searched but could not find any specific lights for a 1998 Trails West trailer; that said, it is pretty easy to determine if the correct replacement lenses are the Replacement Lens - Amber # A44AB and Red # A44RB. The easiest way, of course, would be if you happen to know what Optronics series light you have as these are direct replacements for MC44 Series and BA44 Series. That's not something most people know though, so the other thing you can do is take a measurement. Your current...

  • Will Replacement Red Lens for MC32RB Trailer Lights # A32RB Replace a P2A 01 Light Lens
    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...

  • Finding Replacement Trailer Taillight for SAE Part Number SAE P2 99 DOT 8
    Normally the SAE number isn't a reliable way to find the correct replacement as it is not a part number, but from different customers in the past we've determined that the number you listed is for the Bargman Light Lens # 34-59-010. This lens is a red clearance light lens that measures 4 inches L X 2 inches H x 5/8 of inch deep.

  • LED Trailer Clearance Light that Uses Red Diodes
    Some LED trailer lights use colored LED lights and some use white LED lights. It all depends on the light. But for # MCL44RB1, the LEDs would be white behind a red lens. A light such as # MCL19CRB does use red diodes.

  • How To Remove Optronics LED Clearance or Side Marker Light # MCL40RB For Replacment
    To remove the Lens # A44RB from the LED Clearance or Side Marker Light # MCL40RB you will need to place the tip of a flat head screwdriver between the lens and light assembly(see image). I recommend starting near the corners to reduce the risk of damaging the lens. Once you have the lens removed you will see the screws used to mount the lights. As this hardware is provided by the trailer manufacturer I cannot tell you exactly what it will have but a Philips head button screw is most commonly...
