Extra parts just in case
awesome
Exactly what was needed, makes the job of hanging lights much easier
everything fit great
Very prompt delivery. Part was exactly as described.
The flanges are durable.
1 yr. later, I still do not think about them having issues.
Easy installation and work great!
does not seal like a gromet would but a little calk fix that for my app. which fit into a water tight compartment.
Fit perfectly. Great replacement for our bus lights.
product was as advertised and promptly delivered. The fit was very tight for my Winnebago motor home but it worked fine. The exit for the wiring comes off the bottom instead of the side. That was my fault for not checking. I made it work.
Great product, prefer this much more than the rubber gasket. Made a very nice and neat installation.
I had 4” led lights from a different vendor and needed the flang to mount them. Fit perfectly. Wish they weren’t plastic but it does allow me to remove the light if need be. Overall a good buy.
The product is good quality, matches the bolt-pattern of the hanging bracket BK45BB, and fits the turn/park light STL23CCAB. The tolerances for this combination of items is very snug however, and may require some minor sanding to fit the bracket without a lot of force.
As always etrailer wants it right the first time. This last order was about trailer lighting (LEDs) and I want the best I can get so I urge you as the customer to do your homework as etrailer has done theirs. I also bought new wire, this has been a one stop shop for me.
Thank you etrailer ??!
The trim rings turned the replacement of my stop / turn lights on my trailer into an easy job. They allowed for mounting of the LED replacements with no modifications needed. It was an exact fit in the holes that my old ones formerly occupied. Kudos to etrailer.com for having them.
This item was as described and allowed me to convert a conventional tail light to a LED tail light on my motor home. I was satisfied and will order this again should the need arise. Satisfied customer.
Delivered in a timely manor Great Job!!!
It was just about a perfect fit as a replacement, the original holes were not wide enough for the rubber grommet style holder, this model fits in snug and the trailer lights are all fixed and working perfectly.

Perfect. Lights still working great, and these were the only product to fit the holes that were originally for the Grote incandescent lights.
