Video Transcript for Review of Optronics Replacement Side Marker Lens For STL2 STL3 STL4 STL5 Series - A2RB

Hi, everybody. Andy here with 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..

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 broke a side marker lens putting my trailer away for the winter in the bank barn...this is the ONLY place i could find a replacement lens without having to buy the whole light assembly....that made my day !!!


I ordered bulbs and a lens for my trailer because you never know when you're going to need them. The prices were very reasonable and the they shipped within two days. Great service and price and if I need something for my trailers, I'll be back.


Perfect direct replacement for a part that keeps breaking off from careless loaders. Inexpensive and arrives quickly.


I originally ordered the wrong part. After receiving I emailed back with my specific trailer light dimensions. One of the etrailor employees read and recommended exactly what I needed. Once received it was just like the original.


Exact fit. With the measurements and pictures on "etrailer" site, I was able to order the correct lens first attempt. Thank You !!


I thought I was not going to find a replacement lense for my trailer light and was very pleased when I found it on this site. The replacement was exactly like the original. The description and dimensions given were accurate, so I felt comfortable ordering it. Shipping was quick. I’m very pleased with my order and will come back here for more trailer parts.


Quick delivery time and reasonable prices. I've had great success with Etrailer on all the items I've purchased


Found this light cover on this site. Could not find at any auto supply store or trailer dealer. Only issue was how hard it was to find. No logical search found it. I had all but given up when I happened to see it


Had been looking for a replacement lens for my trailer. Found this one on Product was as described and is a perfect fit.

Still a tight fit. Would recommend etrailer for your trailer needs.

Item was exactly as ordered and received timely. Thank you Etrailer!


Found the replacement light cover we were searching for at a very reasonable price at eTrailer. Fast shipping, too!


This purchase relates to auto hauler trailer I had built which I brought home in the dark and immediately backed it into a tree breaking the trailer light lens. I had been trying to replace that lens for over six months the trailer manufacturer’s sales location was of no use. Attempts to contact the headquarters thru their website fell on deaf ears. Trying to find the lens with the dimension clearly understandable on Amazon or web search did not leave me with any comfort I would be getting the proper lens UNTIL I arrived at The size reference and description gave me confidence that I would be getting the correct lens. After pushing the enter button the have followed up re: order and shipment process in an intrusive way. The part has arrived and fits perfectly. I could not be happier with the product and the feeling that my business is appreciated. By the way did I mention this was just a $5.50 purchase.

Fit was perfect and saved from buying and installing new lights !


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.
