Video Transcript for Optronics Trailer Lights A78CB Review

Today we're going to take a look at the chrome accent ring for the Optronics STL78 and BUL78 LED series trailer lights. This is a snap-on chrome accent ring for the STL78 and BUL78 series LED lights. It's a nice polished, chrome plated finish on this ring. Greatly improves the looks of the LED series lights, and it is a snap-on feature of this cover. Makes it real easy to install, keeps it firmly in place. Give you a few dimensions on this. We're going to do the overall length from this edge to this edge. You can see, it's going to be right at 7 7/8 inches long.

The width on it from the very bottom to the very top is right at 3 5/8 inches wide. It's about a 1/2 inch in depth. Now what I want to do is I happened to pull here's the STL78 LED series trailer light, and here's the BUL78 series light. I just wanted to show you when you install these you can see here's your four mounting points. Right where those are, there's a little indentation. All you have to do is take your snap-on ring, set it right over there, push it right into place.

There you can see, it gives a nice clean finish. Covers up the mounting holes. You can do the same on the BUL78 series. Same way it has the mounting holes with the little indentations. Just go ahead and take your chrome ring, and it pops right over there. Gives you a nice finished look to your trailer. That should do it for the review on the chrome accent ring for the Optronics STL78 and BUL78 LED series trailer lights..

Chrome Accent Ring for STL78 and BUL78 LED Series Trailer Lights - A78CB

Average Customer Rating:  4.8 out of 5 stars   (67 Customer Reviews)


This is mostly about the service. The product arrived within days of the order. It fits fine. However, ordering and support from this company is simply fantastic.


Fit well. Makes my trailer look high end like it should. Very happy with fit and finish. Put on our 2016 cedar creek fifth wheel.


One of my Chrome Taillight trim covers fell off on the freeway. Found it online at Etrailer and order it. To my amazement it was delivered in a few days. Etrailer sent notifications of the entire process keeping me confident and informed that my part was on its way.
Etrailer will get all my business due to Price and Service! Outstanding Job Guys
Thank you!


After a year the chrome still looks great. No problems with fit, they snap tight into place and stay there.


It literally was a "snap" to install. Love dealing with


Worked great as a replacement for OEM that was no longer available for RV. I also replaced the back side marker lights so the front and back matched.
Pat C did a great job in completing my order with substitution for out of stock resistor.


Excellent customer service in speedy de livery


Looks great and priced right!


Obviously, the new ones look great. However, they don't fit as snugly around the replacement lights as the old ones fit on the old lights.


Perfect fit. Item was as described. No problems with shipping.


Product looks great attached to the lights, small diameter and low profile screws need to used to avoid clearance issues when snapping to light, one latch clip on two of the four trim rings I ordered were bent back, fixed with some super glue. Two more clips broke while trying to remove the trim ring from the light also fixed by superglue, not very durable clips, the trim plastic is light and shinny remains to be seen how durable they will be in the elements


Product was exactly what I was looking for and a perfect with my trailer tail lights. Package arrived sooner than reported. Super fast at filling my order.


perfect cover for the marker lights, dresses them up so they stand out

All the products are performing great...........very happy

Looks like the day I got them after one year on my trailer. Thanks etrailer


As described, excellent customer serviceand all my parts arrived in 2 days. will get all my future business.


I was very pleased with prompt delivery and service from you. The products were exactly as pictured on your website and fit my cargo trailer just right. Thank you.


Fits perfectly. Thanks


This company has been nothing but awesome to work with. We experienced a problem with one chrome ring and a new replacement was shipped immediately. We would definitely do business with them again!


Part was as expected and fit as it shou ld.


Cheap plastic but I needed it for a replacement. etrailer, as always, was great


These trim rings are perfect. they will really dress up the lights for the trunk. (purchased lights and trim ring as auxillary lights on an aftermarket hard trunk for my Harley Davidson.)


This is where we always buy our trailer supplies. We have always received a good product at a good price.


Makes the trailer lights look great and just snaps on!


Exact replacement for what was on my boat at 1/3 the cost from dealership. Be careful with the tabs, they are plastic and will break.


Great prices and products. I will be ordering more parts from you all..
