what can I say, the wife requested a smaller opening in her fancy ceramic birdhouse


The product I purchased from etrailer is actually a rubber taillight grommet for trailers, but I use it for a special application on a custom car. We have a custom engine cover on our 55 plymouth wagon and the hole in the cover for the radiator cap was cut too big. I use the rubber grommet to wrap the stainless radiator cap and the gap in the cover does not show. Sometimes with I take the engine cover off to service the engine, I keep loosing the grommet and that is why I keep buying more. This is my 3rd order and this time I purchased 5 items. The product was very easy to order fast shipping and the price was right. If I ever need to get more product I'll always come back to etrailer.


The lights worked perfectly on my C&M truck bed.


Great service!


Very tight fitting. Hard to get the lights in the grommet. Make sure to check the measurments to make sure they fit your trailer. Mine were so tight fitting that I tore a couple getting them in. You can't really tell once it's in. But I guess tight is better than loose!

take a file and file down the sharp lip on the back of the light, it wont cut the grommet and will fit just a little easier, an before installing, soapy water or light oil will help push it in.

Just what I needed.


I have a flat bed on my truck and it uses trailer lights in it. When I looked for replacements all the stores wanted $10 to $30 a peace!!! Etrailer saved me almost $100 over going to may local store. I ordered it on sunday night. I had 2 personal emails telling me my order was ready and being shipped. ON SUNDAY NIGHT!!! I had my order by Wednesday with a follow up email telling me my package was waiting for me at home. My only complaint is why other online stores can provide this service. etrailer, I will be ordering again. Thank You


I've ordered a number of parts from etrailer over the years and everything came on time and was correct it's a joy to do business with them they're very good at getting the correct part the first time


Decent grommet but doesnt work with the 2 1/2 light brackets they sell but does work with lights you will need to trim brackets if you want to use em


Great price
Great shipping
Great george j


Direct replacement for what I had. etrailer always has the products, support, great pricing and shipping options that make shopping with them a real pleasure.


Easy to use, great replacement holder/grommets for clearance/marker lights on trailers


I completely rebuilt my boat trailer and used a lot of parts from e trailer

Every part was of great quality. Very good prices and fast shipping. I would
use them again for all my trailer needs.


product is fine, but was not the one I needed. I ordered because it was recommended in the video and the only option listed under related parts. It was not the part I needed, so after revisiting etrailer I discovered there is another option, the other part is referenced on the page for A55GB, too late for any help.


Install was difficult on my 18' Corn Pro bumper pull trailer. Grommet seemed almost slightly too large for the hole, but I did finally get it to fit and it has been fine ever since for a year now.


These were a perfect fit in the holes that were in the flatbed of my 1969 Chevy farm truck.


Not very flexible and was difficult to get in the hole. Not real clear on whether or not to place the light in the grommet prior to putting in place or put in place then put light. Either way, it was very difficult and I wound up not using it.


etrailer had exactally what I was looking for. Their web site is very helpful. I received the order quickly.


Great product, Great company. I will buy no where else when it comes to keeping my trailers up!


Bought these for less than the price of grommets locally and they fit perfectly and look awesome!!!
A+++ etrailer!


everything i ordered arrived quickly and worked great thanks etrailer


Installed on a 93 Skeeter boat trailer. Very tight fit so I know it is not going anywhere. Very quick shipping.


The lights I ordered and the accessories came and where exactly what was needed.The poeple I talked to when I ordered where very helpful and courteous. I will be very comfortable dealing with them again.


Products are excalty what we ordered to match what was on trailer. I placed order at 8:00pm on Wed night and two hours later order was ready to ship and I had my order Friday for weekend project. AWESOME!!!!! Can't believe they got order out that fast and correct !!


Needs size diameter listed in description.

This grommet is designed to fit 2-1/2 inch diameter light and it requires a 3 inch diameter hole to mount.
