Very easy to install. Considering I had the same lights and grommets on the trailer. Took less than 10 minutes to install.


Exactly what I needed.... I bent up my trailer light box when hauling a tractor, and got the back end of the trailer caught up in a ditch.... so I had the box cut off and a new one welded on.... the old light was broken, so I ordered a new one... as I wanted the same lights on both sides, I ordered two of them from etrailer, and now I'm back in business with the right lights on my flat bed. Fast shipping also was a plus! Thanks etrailer!


Great looking taillights wish I had bought them sooner. thanks

just like a TIMEX watch takes a licking

They seem to work well but do not fit as snug as the ones I replaced. I will add to my review after I take my horse trailer on very bumpy mountain roads and find out if they are going to stay put.


grewat product. easy plug and play for the torn light grommet I had


Great product! My right brake/turn signal stopped working on my trailer, so I purchased a new ST70RB 6-1/2" oval trailer light, along with the wiring plug and this matching grommet, installed them in about 30 min, and it works great! The package arrived quickly and was packed nicely. I found out my fuse was blown on my 2016 Traverse for the right trailer stop/turn signal, but that was most likely from the old light which I think was leaking. I didn't know there was a fuse just for that so I learned something new. I will definitely purchase trailer products again from!


I purchased these Submersible LED bulbs for my boat trailer for two reasons. The first is so road traffic is aware of my intentions of backing up and the second is to make it easier to back my trailer into my driveway at night. The only thing that I find disappointing about this product, is that the wires are not sealed. You have to plug a pigtail in to power the bulb. Although they say it is watertight, I still plan on sealing the plug with some marine grade silicone sealant. Otherwise I am very satisfied with the way these bulbs light up my path of travel.


Used these grommets to install lights on my cargo trailer that I pull behind my motorcycle. I wanted lights that would be sealed from leaking and these grommets allowed me to do that. Easy to use and they hold the lights as expected. Will definitely use these again if I need a similar set up.


These lights are well made and look great. They are a direct replacement for the older version I have. Tinted them to match the trailer. They were very easy to tint as the light surface is very flat.


It was not a good fit and fell out...

it didnt fit well and light fell out of trailer

Mike was easy to work with. Great product with excellent customer service.
Thank you


Product was exactly what I was looking for, Prompt shipping got all products in time for our plan on traveling and everything fit as it should will definatly purchase more from them as needed


Worked well


New grommet was a must when replacing new tail lights. Made instillation of new lights a breeze!!!


Great light - Fit was right on --


Lots of light!!


On a road trip with motorcycle trailer and trailer light with grommet flew out after hitting pot hole..Replacement light and grommet fit and works great. The grommet could be a bit more snug but will watch on next trip. Thank you so much.


Everything was great. I wish you would ship

Your items I received were great. I wish you would ship UPS. USPS does not do a good job. Sits in their post office for a long time and I have to wait for the delivery.


I wish they had come with the recommended hole dimensions for drilling but they work great.

For this mounting grommet the hole you would need to cut in the location is 6-3/4 by 2-1/2 inches. I have included a link to one of our expert questions that answers this exact question, and provides some additional recommendations.

Fast turnaround. Just what we needed Thank you!


I bought these not knowing I would need them. (My small utility trailer had rectangular holes for an older style light) I was able to use the rubber gaskets and the led light and some handy woodwork to make it fit my 1984 trailer these rubber gaskets are fantastic.


Didn't fit the holes in my trailer, although LED lights fit and were same size as original. Measure the cut out in your trailer before ordering. Product was fine but my assumption was it was a standard size.

My fault - they will go in the trash now.

I just had the same experience, needed a thicker or bigger gasket, even trailer manufacturer confirmed this issue, not sure where to get the thicker gasket from? Like You, I thought these were all the same size, the lights to go into the gaskets are...but not the gaskets?
