Video Transcript for Review of Peterson Replacement Red Lens - 55-15R

Hi there, I'm Michael with Today, we're gonna take a quick look at this Peterson Replacement Red Lens. This is going to replace the lens for your Peterson Rectangular Side Marker Light with reflector, this will work for the part numbers that you see on the screen there. So if you're wanting to replace the amber lens for your Rectangular Peterson Side Marker Light with reflector, this will work for that, or if you already have a red lens that's maybe become cracked or whatever the case may be, this will work for that as well. This does have the built-in reflector that's gonna remove the need for a separate reflector, so it will do a good job of shining that light back at its source. It is an acrylic lens, so it is going to hold up well for you.

As far as the dimensions go, our overall width, we're looking at right about 2 3/4 of an inch wide, our height is approximately two inches, slightly over two inches, it'd be 2 1/16, and then our depth, looking at about 1/4 of an inch there for our depth. The distance between our mounting holes here is going to be 2 5/16, you can see there, just shy of 2 1/2 inches. They are gonna include these two screws for you to get this mounted in place. Because this is a direct replacement from Peterson, you can trust it is going to work with your Peterson side marker light, you won't have to worry about fit issues or compatibility problems, it's gonna do a good job for you. So that completes our look for today.

Again, I'm Michael with, thanks for watching..

Replacement Red Lens for Peterson Rectangular Side Marker Light w/ Reflector - Old Style - 55-15R

Average Customer Rating:  4.9 out of 5 stars   (301 Customer Reviews)

Replaces the red lens for your rectangular Peterson side marker light with reflector. Fits old style 114R, 115R, 440/440L, and 441/441L series.


I almost gave up looking for a replacement lens as all the ones I looked at were the "snap on type" until I found a footnote on the etrailer page that indicated there was a manufacturing change for replacement. That change was the screw on type and looking at the body I was replacing the lens on did in fact have screw holes in the plastic mold of the body. (Was not aware they were screw holes). Without that little footnote etrailer provided they would have lost the sale.

Still there, doing it’s job.

I used this lens to replace one that was damaged on the side of the tail light/brake light assembly on my utility trailer. It was a Perfect Replacement. You would never know it was replaced if you didn't know it already.


This is Gary’s Rat Rod. The two Peterson lights are on the rear of the vehicle.

Had great service from etrailer. They researched my question, and they gave me the right answer, and sent me the right part. etrailer is the place to go! Highly recommend!

No issues!

Ordered a replacement lens for broken trailer light. Was very easy to order online and it fit perfectly.


They fit like they are supposed to. Great alternative instead of buying the whole light assembly. Will defiantly buy again.


First of all, it was great to find this small replacement part for my trailer tail light. An easy to navigate website as well. The delivery was very fast. I have a bass boat trailer and a utility trailer and will shop from now on for my trailer parts.


A very straightforward, well organized and documented website, and prompt shipping.


Very friendly customer service and knowledgeable. I needed a small trailer light that I couldn’t seem to find anywhere and the e trailer representative easily located the right to the part with expertise- many thanks


This replacement trailer lens works. The original lens had plastic prongs and popped into place. The replacement uses two screws. The only issue was the wait time to receive the part - lost in transit by USPS for an extra 9 days.


Replacement reflector for the boat trailer arrived promptly, was the right one for my rig, and was easy to install myself.


The customer service involved in this order was awesome! Terri was so helpful and was very friendly with a nice conversation to boot! In today's world, customer service to me is the most important aspect of the transaction!


My experience with was great from beginning to end. They provided information that gave me confidence I was ordering the right replacement part. Price was good and it was shipped fast and received ahead of schedule. I was very impressed!


Nice product fast shipping


This was an exact replacement item that I easily found at

Exact replacement part and is working great.
Charles A - 09/14/2021


Product served the function as advertised. Price was very reasonable. Cheaper alternative vs. replacing the entire tail light.


Very valued supplier with quality parts and excellent customer service!


This part is exactly what I was looking for. The video showing measurements of the lens was very helpful and confirmed that this part was the one I needed.


Easy replacement…shipped quickly


Fit great. Old part was held on by tabs. This is screwed on. Much nicer.


Excellent Service


The lens I purchased came quickly and fit my trailer light perfect.


Slow to arrive.


Fits great, was the right replacement p art


Exactly what I needed.
