GREAT
right size
Quick shippingProduct arrived faster than expected and the right part.
Quick shipping and performed as advertised.
the grommet didn't fit so i re-used the old one. apparently the grommet size varies with applicaiton.
Your standard rubber grommet for 4" lights. Fits something like STL23CCAB perfectly, as well as a 4" taillight I had already.
The grommet is excellent quality. Heavy duty construction and fit the light and frame assembly perfectly. The shipping was extremely quick, and the price just right. Would recommend etrailer.com highly.
Fast shipping, item exactly as described, fit perfectly and look amazing.
These are good grommets for the price. I've purchased a few over the years and they have never failed. I've only replaced them because they got some over spray from paint on them or something like that and it's cheaper and easier just to buy another pair and have them look brand new again. I use them on a Jeep built for rock crawling and I've attached a picture of one of them on the Jeep but this is an old set and not the best picture but you get the idea. They hold up well to abuse.

Still working well and holding up to the punishment I put them through.
An exact replacement
The grommets did not fit into my original openings. I had to use a die-grinder to enlarge the holes by 1/8” all the way around. Once complete, they fit pretty good.
Product as described. Service and communication excellent.

I ordered the STL101RB Trailer Tail Light - Stop, Tail, Turn, Backup - LED to replace the standard tail lights on my Yamah Drive G19 golf cart. They replaced to stock ones perfectly as a neat way to add a backup lights for a custom feature. The backups led are actuated by the reverse switch on the dash.
It should be noted that the ground terminal on the two wire pigtail connection is not wired internally to the backup LEDs. They rely on the ground supplied by the three wire pigtail. Not a big deal, but worth noting. It throws a curve when bench testing.
These lamps add a nice custom touch!
Great customer service! I had an issue with the order I called customer service and they went above and beyond to assist with the issue. It was resolved quickly and professionally. I was very pleased with the response which gave me faith that I will definitely purchase from them again! Thank you!! Happy Thanksgiving to all!
Items arrived as described. Good quality, price and fast delivery made this purchase an overall great deal. The lights, cables and grommets I haven’t test them, waiting for my truck replacement bumper to arrive in September and have the body shop install them for me. I will update my review, but for now I recommend this products and the seller.

After a year using this product function-ability still performing as described. I recommend this product and seller.
Fits a little loose but once all in and lite in its good enough
i never had a bad part
I've ordered a variety of items over the years from etrailer usually to repair and sometimes upgrade trailers. Etrailer has the items I'm after. They get the order correct and shipped in a timely manner. With that kind of service I'll keep coming back. Thank You.
Very pleased now other drivers can see my tail lights. Better yet turn signals & stop lights are bright .I would recommend these lights to any drivers that want to be safe on the highways

Very well I should have ordered these years ago.
I have been looking for a long time to find a replacement for this light.
I could buy others, or kits etc, but I wanted this same light.
I contacted the company and explained what I needed.
They had it in stock as well as sealed light, the wires and connections.
It was delivered Very promptly, within a matter of days.
Excellent service.

Superb. I thank you for the service and professionalism that the company exhibited.
Perfect for what I needed - seals for computer cable access in a desk...timely delivery...excellent!
I ordered a set of tail lights for my boat trailer and they shipped fast. The customer service is really great too. The product is high quality and I'm very happy with it. The only issue I had with etrailer.com is they charge far too much for shipping and they only use UPS. So people like me who have a frequent shipper contract with other freight and delivery companies can't get it shipped at a reasonable cost. It is unreasonable to me to pay just as much for shipping as the product cost. Etrailer if you are listening, please ship small things in USPS flat rate boxes and allow customers to use their frequent shipping agreements with other delivery services.
The amber led lights I received were great and I installed them in the front of my 2002 Pontiac Firebird cuz I clipped another deer and ran over a raccoon in the same night and they took out my front lights again. So, rather than try to purchase an original set of turn signal and fog light assemblies along with the expensive bulbs, I converted it over to led and it is a great upgrade for an older car. The problem is that the three color coded wires came with no directions that told me which wire was ground, park, or turn. I had to figure it out as the color codes are different on my car. I would send a pic, but it is on my cellphone.
