Restoring a 70's trailer for a guesthouse on my place, didn't know I'd find anything to replace the old taillights I'd glued together a million times, the last storm took them out..was very pleased to get these! Great price, thanks, have bookmarked your page.

Thanks very much for your assistance and great price for my hard to find part.

by: Eric 09/27/2022

It works on my 1988 Scamp, 13 footer. Yes, I had to drill new holes in the fiberglass to match the four holes on these replacement LEDs. But I just used silicone to cover up the old holes. The SCAMP did not leave a lot of wiring to work with. But we used butt-splices which held pretty well. The LEDs are very bright. Yes, I would buy these again. etrailer staff was very nice and worked hard to get them shipped on time. Perhaps I'll take a photo later.

They work. They are bright. They can be seen from far off. They are LED so they use less power. I would buy them again.

Good product. This was used to replace a lens on an earlier style taillight. It took some bending of the original light bulb socket to do the installation, but it otherwise suited the repair.

Round Tail Light Lens Replacement for Optronis Light
We do have a variety of replacement round lenses for Optronics branded tail lights, but I'll need some measurements and photos to recommend the correct ones as the numbers you found are related to the testing that the light undergoes and doesn't really say which light it is. The most common option we have is the part # A90RB which is for an ST90 Series if that's what you have. If you have something else please feel free to filter through the linked selection or shoot me some photos and...

Does Optronics Tail Light Lens A90RB Include a Clear Portion for a License Plate Light
This lens is meant to be used as a replacement to the Optronics tail light, part # ST90RB. It does not have a clear portion for a license plate light. You are looking for a light like Optronics part # ST9RB or part # STL9RB. You could also use Optronics part # ST17RB. I have linked to these parts below.

Will the Optronics Round Transit Stop and Tail Light A90RB Fit a Weldon 1010 Taillight
The Replacement Tail Light Lens for Round Transit Stop and Tail Light part # A90RB is designed for the Optronics Transit Light part # ST90RB therefore I cannot confirm it will work on your Weldon 1010 Taillight. They do have the same diameter so it may work in its place but otherwise you would have to replace the entire light assembly in which case this will be your best option for this.

Diameter of Lens A90RB

Solution for Older Trailer with Broken Taillight Lens
Easiest solution would be to replace your entire light assembly as I would have to see a picture of the light/lens to see if we have it. Based on your description I would have no idea on whether or not we carry it. Due to the age of your trailer I would suspect we do not carry the lens if it was original equipment. If this is the case the best option I could make would be to replace the entire assembly with a light from the link I attached.
