Video Transcript for Optronics Trailer Lights AL17RB Review

Today we're going to be taking a look at the replacement side marker lens for the STL16RB, and STL17RB Trailer Lights. This lens is SAE, and Department of Transportation Compliant. It's made from a red, acrylic construction that's strong and durable. It's going to feature the reflector that's built into the lens and this is a genuine replacement part. I just want to go ahead and show you how to it installs. What we're going to do is install it.

You'll need to remove the main lens. That's going to be held on our four screws, so you need to remove the screws, remove the main lens from the trailer light, and then remove any parts of the old side marker lens. Then you can take your new one, and it's simply going to slide and fit into the groove, along the bottom. Now that's going to be held in place by re-installing the main lens. You want to hold that in place, replace the main lens back into position, and then you would secure everything by re-installing your hardware. Be careful not to over tighten these so you don't damage the main lens.

Then once you have that tightened back down, your side marker lens is going to be held securely in place. That's going to do it for today's look at the replacement side marker lens for the STL16RB, and STL17RB Trailer Lights.

Replacement side marker lens for LED STL16 and STL17 Series.


This hard to find side marker lens fit perfectly. It saved me the trouble and expense of ordering and installing a whole new tailight. It also arrived 3 days before the due date! Very happy with this order and the service.


Very good service and easy to order from site.


This is not an earthshaking part, but when you need one, there is NO substitute. I was not thrilled about the prospect of spending a good chunk of change for an entire new light assembly and was thrilled to find This part is exactly what I needed, and it was exactly as described, and the folks at are second to none when it comes to great prices, fast shipping and GREAT customer service!

My etrailer parts are still working and still looking good! Great parts, great people!

Mike S. was very helpful in helping me find the right replacement lenses for my sons boat trailer. My wife damaged them when she hit the one with the lawnmower. Thanks again Mike for the help for the great service and super fast shipping.

Trailer light lens was a perfect fit and great service

Product was exactly as described and pictured. Lens was exact replacement for my original side marker lens. I also purchased the replacement taillight lens. Shipping was fast and items arrived in perfect condition.

I purchased these same items a few years ago from when someone cracked my left taillight. This time my right taillight got hit. Both times my experience with has been excellent. I will buy from them again without hesitation.


Exact replacement for the submersible 'over-80' Harbor Freight LED units. Saved me a small bundle, since the LEDs inside are actually in a clear, sealed enclosure, and the red lenses are just covers.


I am very impressed with eTrailer. Knowledgeable people provide quick and detailed answer to your questions, their website is quite powerful and the entire shopping experience is smooth and transparent. I will recommended them without hesitation!


eTrailer is a great resource for replacement trailer light lenses. Stationary objects keep running into my trailer lights and smashing the lenses. Local stores carry only a couple of lens types -- not the LED light lens. eTrailer's prices are very good, and my order shipped the same day. I will continue to do business with eTrailer.


Etrailer is always my "go-to" place!


Great product. Fast shipping from etrailer. Fits perfectly a low profile LED light assembly purchased from Harbor Freight. Side marker fits in fine too.


Bought this last year. It was excellent, and was the exact part I needed after this piece of my trailer tail light cracked.


So pleased with etrailer. Not only do they have the right part, they go above and beyond to make sure I have what I need. It was only a small part $ but you would think I was spending $$$$.

etrailer is the best. Customer service A+


I took a chance on ordering this as a replacement for what I had on my trailer just by the looks and it fit perfectly. Time of delivery was prompt and it fit just right.


Exact replacement for damaged tailight at marina.


Just as ordered. Fit my application perfectly. Arrived in perfect condition.

Working as it was suppose to. Perfect fit.
Todd R - 09/20/2019


Product arrived in a timely manner and was exactly what was shown on the website...will use this vendor in the future.

Thanks, etrailer


Excellent fit for our trailer light. Shipped right away. Would be helpful if measurements were included in the description.


Item was received 3 days earlier than stated following placing the order. Triple A service in my mind from etrailer!


Perfect OEM match for the LED lights on my trailer, great fit.


Excellent product, perfect fit


exact match for trailer light that got broken, staff were very helpful, thanks


Perfect Fit for my trailer brake light. ..


Exactly as pictured and matched the original from my trailer.


Got exactly what I ordered and needed in a quick amount of time. Thanks!


Exact replacement at a reasonable cost, with prompt delivery. good quality part.
