Having used etrailer in the past, I expected items as ordered, properly packaged, and with acceptable prices. The prices are now high and I could have shopped elsewhere, but I recall the staff reps were very helpful. And the canned excuse of "Covid" cannot apply here. The staff (Brittany) was indeed very helpful.

The box of lights arrived (about 20 units purchased). Surprised to find the box full of lights were not individually packaged and just thrown into a heap and covered with brown paper filler. Many of the lenses were scratched (none had the protective cover expected) and my order was to be 100% LED. I got a mixture of LED and incandescent light bulbs.

I was assured by the very helpful Brittany that the lights should be individually packaged and certainly should not include anything other than LEDs. So she shipped me a new order along with a return label for the first order received. The second order arrived early (arrived on a Friday and was told it would be the following Monday....and I'm thankful). Interestingly, the same 'tossed' parts were discovered, and was even worse because the lenses were tossed in separately from the light bases. With the same scratches, and even more individual parts. Contrary to what Brittany said, this is obviously the new way of doing things at etrailer. So I will take the collection of pieces thrown into a box and call it a day. However will not purchase from etrailer again. I will use the local vendor where I know I will pay less and the parts will be as provided by the factory and not heaped together in box with hopes that all electrical components will actually work.

I went the extra step of NOT doing this review because I knew it was just an odd circumstance and, as Brittany stated, my shipment will be used as a training guideline for what NOT to do. So I did not reply to their request for this review. Having opened the collection of parts again jammed into a box, I changed my mind. And thus this review.


Purchased LED lights to re-wire a 12-year old trailer. etrailer had all the lights/gaskets needed. Perfect fit to the original OEM lights.


Ordered this to fit the glolight led trailer light as this light would not fit in to the one on my trailer securely.

Wiring is NOT conventional..
None of
the harness wires matched up to the flat 4 wiring.
Red was yellow green was brown etc.
And wiring or color ceding was included with the 7 pin harness


The tail lights when packaged were not protected from rubbing against the box which got scratched during shipment. The trailer wiring from Curt appeared to be good quality, but the mounting bracket that secures the 4 pole flat plug does not hold it secure and it is loose. I will be sending it back.


I ordered a 10LED tail light for my trailer with the grommet and received them very quickly. Took them out and put them on my trailer and they work just fine Thanks.


The grommets worked perfect. They appeared a little small until the light was installed and they filled up the space perfectly.


Did not fit properly in my 2012 Continental cargo car trailer. Was way to loose to install so just reused originals. Did not send back due to not enough money to warrant the hassles of a returning.


A perfect replacement for the weathered and cracked originals.


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!


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 came highly recommended to me after watching a video on YouTube from both and other sources, who showed the superiority of Optronics PVC Grommets to other brands available. The fit to the lights were much snugger and the grip on the light brackets was better, so even though the light sets I purchased came with grommets, I ordered these and am very pleased with them. The lights fit very snug in the socket holding them, and I'm much more pleased with Optronics grommets than the others. I highly recommend these. I rate them 5*s out of 5. I will be purchasing more. I received them well packaged and within 3 days of ordering. Fantastic! Thank you


easy replacement from OEM part. No leaks when submerged.


Great looking taillights wish I had bought them sooner. thanks

just like a TIMEX watch takes a licking


With some trimming it made a nice finish on reverse light Item #BUL111CFPG for 2008 Ranger Bass boat


I had lost a trailer light from one of my new trailers. Logged onto etrailer, found these and purchased them. Perfect fit. Thanks etrailer!


Poor delivery time and I had to pay for it!!
You said it was in stock but that really didn’t mean anything!

Jenny N.


I am sorry that we were not able to ship this sooner for you. We have added additional warehouses and staff to help during the busy summer season. I will have our Customer Service team reach out to you.


I was pleased that I was able to get exactly what I needed and so quickly.


Right product for the job


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.


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.


The “pvc grommet” doesn’t fit boat trailer snugly.


While these grommets allow the lights to fit inside them perfectly the grommets themselves are fairly loose in the trailer.

I have a 2011 Ironworks challenger series car hauler and it had chrome trim rings around the grommets which I transferred to these and they aided in tightening things up somewhat but it just doesn't seem to fit like I'd expect.

Etrailer is great and always has prompt and courteous service so I am still a customer for all my trailer needs.

Darren K.


Not quite good enough, I ended up going back to my old grommets for a tighter fit and better adhesion of the trim rings.


Description as advertised accurate and quick service


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.
