Thank you for the photo of your broken light lens for which you are looking for a replacement. It appears that your lens had two tabs for installation, rather than screws, with one of them now being broken off.

I reviewed all of our replacement red light lenses, shown on the linked page, but none shares this exact same construction. The Peterson lens # 55-15R that you referenced appears to match in design and shape but it uses screws for attachment. This lens measures 2 x 2-3/4-inches.

You should be able to find a brand and part number for your original light on its base (lenses have only DOT codes molded into them, not the actual item part number). If you can find a maker's name and part reference you might have better luck narrowing down potential replacements.

Also, if the lens you referenced happens to have the exact correct dimensions but just mounts differently, you might be able to adapt it to fit but clearly this will require an alternate method other than the supplied screws. It would likely be necessary to use a clear silicone adhesive (available at any hardware store in a caulk tube) to both mount and seal the new lens to prevent entry of moisture.

In case you prefer to install a whole new light I also linked our main page for trailer lighting. Just click on the filters on the page to narrow the items shown.
