Hi, everybody. Andy here with etrailer.com. And today, we're gonna take a brief look at this replacement side marker lens. Now, this replacement side marker lens is going to work for the STL2, STL3, STL4, and STL5 series. And let me get out my ruler here and just give you some measurements. The overall length of this cover is going to be sitting right at 2 3/4 inches long.
And the width, we're gonna be sitting right at 2 inches wide. And the depth, we're gonna be sitting right at an inch and a quarter. And then measuring those bolt holes center to center, let me line that up, we're sitting right at 2 3/8 inches, center to center. Now, it is important to note that the hardware is not included. But if you have one of those series of lights that I have mentioned previously by those model numbers, then this will work for you as a replacement.
Well, that's gonna conclude our look today. I do hope that it was helpful for you. Again, my name is Andy. Thank you for joining me..
I scraped this side lens off my trailer in a tight spot and could not find a replacement. While shopping at etrailer for a brake controller, low and behold, I saw the lens I needed! It was only a buck fifty nine so I bought eight of them. I also bought the controller but that is another etrailer success story that I will tell later. Etrailer is a great place to do business!
The shipping was quick and the product exhibited good quality. I was pleased. I would buy from them again.
Perfect replacement for our trailers broken tail light. The measurements were accurate and very helpful. Product was quickly shipped. Very happy with my purchase.
The part I ordered was a perfect replacement for the broken trailer light cover. The part shipped, and was received very quickly. Also, the staff did a great job communicating shipping/tracking progress.

The part was good. It accidentally got broken when a lawnmower got too close while mowing, and broke it and another tail light cover. Ordered that part again, along with the other broken cover from this site several months ago, and they were both perfect fits as well.
Quick shipping great price!
I looked everywhere for these lens. Glad etrailer had them!
Perfect replacement for my broken side marker lense.
Excellent condition parts

Exactly what we were looking for! Both back marker lens caps were cracked and I couldn’t find these anywhere else. Good price, fast shipping. Pleasant experience as always with etrailer!

Working out great, etrailer is one of the only places that carry’s this specific marker lens.
I did a search on your site based on the numbers printed on the lens. I think the numbers were related to federal safety standards, but regardless, the numbers were found in the 'help' feature, e.g. someone had asked about a lens with this number printed on the lens. The customer service reply to the previous question led me directly to the correct lens. The measurements in the picture ensured me that I was ordering the correct item.
Thanks!
Worked perfectly.
I just wanted to say thank you for lighting the way again. Great price and fantastic delivery service. Replaced broken lenses and a little touch up looking new again.
Definitely will be buying in the near future.

Perfect
My daughter knocked the trailer light lens off. I Googled the number on the broken lens and found etrailer.com. I ordered a new one and had it in about a week. Could not have been easier and the cost was reasonable. Thanks folks.
