I see what you mean with the scratches. I will have our Customer Service team reach out to you. We certainly have replacements sent out to you.


Fixed 2 sts of lights fit like a glove perfect. Thanks E trailer


This lens is a replacement for a lens
I lost on a magnetic light set
That I use when pulling my car with
A toll dolly. Stacey was right on for
The perfect replacement. It fits just
Like the original lens. Very fast shipping. Will order some more red and
Amber to have on hand if any Crack in


Works for magnetic base lens replacement


I had neglected to tie a safety tether on my magnetic-mount taillights and one came loose and got dragged a few miles on country roads, losing both lenses (amber front and red back). Replacing the light set would have been more than $50.

Ordered replacement lenses from etrailer. They came promptly, snapped on perfectly, and both together cost less than $10. Lights are good as new. I can't imagine a better deal.


The part I ordered was a replacement lens cover
to repair my magnetic boat trailer lights. The lens cover was the exact part I needed and fit perfectly.
The customer service at etrailer (Nichol) could not be any better. When future parts needs arise
I will definitely be calling etrailer again.


My set of Regal magnetic trailer lights lost both the amber and red lens on a cross country hauling trip. I thought it would be tough to find replacements that would snap in place but these lens fit perfectly. They snapped in place and will work great. An easy fix with fast delivery.


this was a replacement tail/stop light lens for a magnetic base trailer light system.
it was delivered on time and it fit my tail light

can't get much better than that


Found the web site and checked out the replacement lens for magnetic tow lights. Excellent prices on the amber and red lens replacements, perfect fitment and the price for ship was right on. Will do business again, happy to find Thank you!


Product is perfect replacement lens for the taillight on my utility trailer.

Ken S.


Great! Still looks and works like new.


I bought these to replace broken lenses on my tow lights purchased from a discount hardware store. They fit well, but are a very small bit loose. Nice items.


Excellent! Direct replacement for my Magnetic tow lights.


Got exactly what I needed. Nice staff.


I needed two sided trailer type lights. These look to be very good quality, and mounted so very easily. I think these are going to be perfect for what I needed. thanks.


I got the right size this time! The last lens I purchased (elsewhere), was just a snippet too large so I had to glue it in place. When I managed to break it, I ordered four from you folk. It was the right fit, so it wouldn't go on due to excessive glue ALL the way around it! It took about two hours, one band-aid, and a few curse words, but I finally got enough of the glue off and the new lens popped right on.........perfect!! Many thanks, I'm glad I ordered four......after all, bound to screw up a couple more!


Lens repaired my mobile trailer lights


What a great company. I received my order the first time just after christmas and the USPS had actually destroyed the box. It was well packed but looked as if run over. I called Etrailer and they immediately sent me another one. It arrived perfectly and fit like it was an original part. I cant say enough. This company is awesome and really knows how to take care of a customer.


Was an exact fit for my magnetic tow light lens


received the lens is good time and it is exactly the one I have been looking for as they are hard to find.
Thank you very much


Product was exactly what it was supposed to be. I had a difficult time finding anyone who stocked this part until I found etrailer


Etrailer does not have it on their references, but it is compatible to the AutoLamp 567 4" 5/16.


I want to order amber but was not sure if you carry the same size as the red or what part number would be the same size.


Exactly what I needed at a great price although it cost more to ship the lens that the actual lens cost but it was worth it.


Just what I needed.


I picked my lens from your excellent parts pictures as I did'nt have a part or model it in the mail and it fit perfect! thanks, I'll be a regular customer.

  • Replacement Lens for Round Magnetic Tow Lights
    The only magnetic tow lights we offered with red and amber lenses were the MaxxTow Magnetic Tow Lights (Discontinued) part MT70097. Unfortunately, the lenses on this light are not replaceable therefore your only option would be to replace the entire lights all together if this is what you have. The Replacement Tail Light Lens part # A52RB that you referenced is for the Optronics Single Face Trailer Tail Light part # ST51RB or the Optronics Dual Face Trailer Tail Light part # ST52RB. There...

  • Replacement Trailer Lens Cover for 4
    The best way to determine which replacement tail light lens you will need is to try and locate a part number on the light housing. The SAE, Society of Automotive Engineers, number is not the part number of the light, it is just a number on the lens that means that lens has passed SAE guidelines. These numbers are usually on the lenses of most all trailer lights but do not give the information needed to locate a replacement. If you are unable to locate any markings on the light housing,...

  • How to Remove and Replace Lens on Optronics Pedestal Mount 3-Function Trailer Light ST51RB
    In order to show you how to remove and replace the lens on the Optronics Pedestal Mount 3-Function Trailer Light ST51RB I pulled one from our warehouse. For reference, this light uses replacement incandescent bulb 2057, available at automotive supply stores. If you refer to the linked video you will see that we found the best way to remove the lens was to use a pry tool. In this case we chose to use a plastic bottle opener since its less likely to damage the lens than a steel screwdriver...

  • Recommended Tail Light Replacement Lens for Vintage Glass Lenses
    If you just want a lens, I recommend the Peterson Red, Round Replacement Lens # 420-15 which measures 3-3/4 inches diameter and has two holes for mounting screws.

The The Optronics Red Replacement Tail Light Lens for ST51RB and ST52RB # A52RB is a 4-5/16 inch diameter red lens. Either one would need to be sanded down for the proper fit in your custom...

  • Replacement Lens for my Magnetic Towing Lights
    We offer replacement lenses for the part # RM-2120 in the red color using the Replacement Tail Light Lens Red part # A52RB. These are red lenses and to get the black out look you will have to paint it. I do not offer a blacked out version. Double check the diameter of your light to ensure this does in fact match yours. The outside diameter of the lens should be 4 5/16" for this to work out. If you have something different let me know.

  • Recommendations For Replacing A Burnt Out Bulb In Magnetic Towing Lights
    Most of the time the lenses on magnetic tow lights will be able to just pop off, but not always. If there is a gap between the lens and the base, it will work. If there is no gap and the lens is sealed to the base, you will need to replace the whole unit with something like the Hopkins Magnetic Tow Lights # C6304. The LED lights will tend to last much longer than incandescent lights and will draw less power, so it is highly recommended. If you do have the gap and can get the lens off,...
