Video Transcript for Peterson Rectangular Side Marker Light Replacement Red Lens Installation

Hey, everyone. It's Evangeline here at etrailer. And today, we're taking a look at our replacement red lens for your Peterson side marker lights right here at It happens, maybe you are backing up your trailer the wrong way and you clipped your side marker lights so you need to find the replacement part, or maybe you have a new light and you're just looking for the correct parts for it. This is an exact replacement for your Peterson light, but it can also work with your other lights like what we have here as long as you get the measurements right. We have a lot of replacement lenses here at etrailer and a lot of them even fit this type of a light, but this is one of the few that has included hardware.

So, if you need to replace your old one and you couldn't save the screws from your old lenses, well, this has it there for you. All you need is a small Phillips head screwdriver. So, just line up the lens with your light, pop in that screw, and then tighten them down. And just like that, you we're able to replace the red lenses on your side marker light. With this having the screws included, definitely helpful for the install.

I know sometimes you don't have the hardware included and you're gonna have to find your own or see if you can salvage the old ones. So hopefully, that will help you out with figuring out if this is the right fit for you and your lights. So, if you have the old style Peterson light or if you have another light with similar dimensions, this was a look at the replacement red lens for your Peterson rectangular side marker lights for your trailers here at

Hard to find trailer parts in stock. Good customer service!


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.


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!


AS USUAL.....etrailer provided the RIGHT item in a timely manner !!
Thank you etrailer !!!!


Replacement lens for trailer arrived exactly when they said and fit perfectly.


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





I didn't get my trailer inspected for a few years because of the broken lenses. I was happy to find etrailer had them and I was even happier when they fit perfectly. Would definitely recommend etrailer.


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


Slow to arrive.





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.


Perfect Fit. Very courteous customer se rvice.


Fit perfectly, and included the two scr ews.


Product was great. Fit well.


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!


I needed a replacement lens for a lens on my trailer that was cracked. etrailer's online catalog allowed me to replace this cracked lens at a great price, and it made the purchase go from optional to "why not? Must have". Thank you etrailer.



Thanks for your attention to a customer. I must admit, the reason I bought your lights was to make my trailer as attractive as possible to a potential buyer. I sold the trailer not long after I made the purchase with etrailer. Again, those lights, the price, everything, was first class. I no longer own a trailer, or will be buying a trailer in the near future. I owned several, two-wheel small trailers beginning in 2001, but I have disposed of them all. I am 68, and I have moved to a house with no driveway where the trailers were kept. If you glean anything from this email, it would be older owners are less likely to generate sales.


This reflector fit correctly in the side of the tail light assembly to replace the broken reflector. It also comes with both screws to install it on the light assembly. Very happy.





Fair pricing, and prompt delivery.


Fast shipping!!!


The product was as expected (boat trailer small reflector plate). Thanks

George, it worked fine....thanks for asking...Tom


I've purchased a variety of trailer and towing parts from etrailer over the last few years. I've been very happy with their service and delivery speed every time. This time was just for a replacement tail light lens for a boat trailer I bought recently. I was very surprised to find one anywhere but etrailer had it!
Thanks for the great service.


This is exactly what I need. From the picture I wasn't sure because the ones I replaced had little catches top & bottom instead of screws, but they are a good fit. I didn't realize the screws were included - nice bonus.

Still holding up well


I have had three different brands of tail lights on my boat trailer with the side lens broken, they fit perfect on all three, Great replacement. Now I have three spare tail lights. Thank You. Charles


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


The lens cover that I ordered came as described and fit perfectly on the unit that I ordered it for. I had searched everywhere for a replacement until I discovered and I'm glad that I found! Thank you all for your help!


Took me a while to track down this lens replacement, but had it and shipped it pronto! It's a perfect fit on our utility trailer. Hubby had no problem attaching after reading that this replacement lens screwed in place, unlike the original pop-in lens. (Bought an extra for next time the trailer "backs into" the garage wall!) Thanks etrailer!
