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.

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.

Restoring a 1991 2 horse trailer. etrailer had all the exact lights made by Peterson, 35 years later.



by:

super tight fit. used a little lube to install. no cracking or deterioration as of 1 year



by:

Heavy duty grommets



by:

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.



by:

Worked as it should.



by:

Product as described. Service and communication excellent.



by:

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!



by:

Product was delivered on time and meets my expectations for quality. I would buy this again and from eTrailer because of their service.



by:

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.

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.

Actually, It came out of the rubber gasket when we put the boat into the water====Never found it!

Hi guys,
I'm usually the one answering
reviews
These guys are great! My client emailed the link & told me to order these for our horse trailers.
They've held up, to the point, we're not even close to needing to replace them.
We haul quite a bit. These lights have been tried & true, day & night.
When you're hauling a lot of livestock, you want people that have no clue what that entails, to see your lights well before they get near your livestock ; these lights do the job perfect!
We've outfitted 3 separate trailers with this company. We restored wires, lights, & pretty much everything along those lines ;from a 2 horse, to a large stock, & a gooseneck. All the parts come quickly, are all there, & work & fit great. What more can you ask for?!



by:

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.



by:

Perfect for what I needed - seals for computer cable access in a desk...timely delivery...excellent!



by:

The rubber grommets are fine just a little tight for my existing lights to fit in. I had to use some glass cleaner to get them to even have a chance of going in and a lot of brute force. Now I'm not sure if it is because they weren't matched with the LED's I already have or maybe the rubber is not so "rubbery" I've had issues with other "rubber" things. All in all they replaced the cracking existing grommets and they look good.
The 2" marker lights were a waste of money not because there are issues, but because I needed 2 1/2" ones so these don't fit. I ordered wrong, but the quality of the lights look good.



by:

I’ve used etrailer on multiple occasions and have been completely satisfied with their service and professionalism .

Superb. I thank you for the service and professionalism that the company exhibited.



by:

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.



by:

Here's the pic of my finished project. Thanks for ur help.



by:

The product arrived quickly and was just as described. My trailer is older and I was having trouble finding replacements for the tail lights. Their sales rep, Cathy T., was knowledgeable and friendly. The next time I need parts for my horse trailer, I will go directly to etrailer.



by:

Communication with etrailer has been really good.This item was back ordered and they let us know immediately.

The grommets fit well into the holes and the lights pop in snuggly.



by:

extremely quick delivery. excellent service rep. AAA+



by:

etrailer as always has what I need, ships fast, and product is "as advertised"!
A pleasure to talk to the tech's when I have questions and even go as far as calling manufacturer to verify equipment selections.
Keep up the GREAT work.



by:

Working well the trailer is parked out in the weather all year and the grommets are not hard of cracking

  • Which Trailer Tail Lights Work With 4" Trailer Light Mounting Bracket BK45BB
    I would be happy to help! The Trailer Light Mounting Bracket for 4" Trailer Lights, Steel - Black Powder Coat # BK45BB you were looking at works with 4" round lights so I recommend the Optronics LED Trailer Tail Light - Stop, Tail, Turn - Submersible - 21 Diodes - Round - Red Lens # STL55RB. You will also need Rubber Grommet # A45GB and Wiring Pigtail # A45PB. I recommend using heat shrink butt connectors # DW05744-5 for a weather tight connection. I included videos of the products...

  • How Thick Of a Plate Will the Optronics Rubber Grommet for 4 Inch Round Lights Fit
    I went out to our warehouse to measure the seat of the # A45GB grommet that you referenced. It seems like it will be a tight fit for your 3/8 inch bumper. The grommet seat measures 0.24 inches. Another option for mounting a 4 inch round light on your trailer, instead of the bumper, is to use the Trailer Light Mounting Bracket # BK45BB. This may not work for your application, but it could also be modified to work how you need. This bracket will work well with the rubber grommet # A45GB.

  • Does Fusion GloLight Tail Light part # OPT64WR Require Resistor
    Since the Fusion GloLight Tail Light part # OPT64WR is designed to be a trailer light and not a vehicle light it does not have any resistors integrated into it. Trailer wiring does not require this because the signal comes from the vehicle wiring which already has the flasher unit functioning. If the light was to be installed on a vehicle in place of a blinker circuit a resistor would be needed or a digital flasher installed on the vehicle instead of a thermal unit. The proper resistor...

  • Is Peterson Red Round Replacement Lens # 420-15 Interchangeable with DZ 77-845 Tail Light
    The Peterson Red Round Replacement Lens, # 420-15, is not interchangeable with the DZ 77-845 light that you referenced but I may have a solution. For just a bit more than the cost of a lens, you could replace the entire light assembly with the Sealed, 4" Round Trailer Stop, Turn and Tail Light, # ST45RB. 3-Wire Pigtail, # A45PB, and Rubber Grommet, # A45GB, would be needed in addition to the light. Unfortunately we do not offer a replacement lens that will work for your current light.

  • Can the Optronics Sealed, Miro-Flex Trailer Clearance Trailer Light Be Used as a Brake Light
    The 3 diodes in the Miro-flex light, # MCL51RB, would not make a very good brake light. They would not be as bright as the regular brake lights already on the trailer. You would need a light designed to function in whole or in part as a brake light such as # STL23R24B. With this light you would also need a wiring harness, # A47PB. To mount it you could use mounting bracket, # BK45BB and grommet # A45GB. You could also flush mount it using the mounting flange # A45BB.

  • Recommended Grommet for Optronics 4 Inch Round LED Light # STL55RB
    Both the Rubber Grommet # A45GB and the Notched Rubber Grommet # A45GNB that you referenced will fit and work well with the Optronics 4" Round LED Light # STL55RB. The only difference between the two grommets, as you mentioned, is the notched cut out in the lower portion of the unit. This is not necessary for wiring or fitment, but it will allow for a bit of an easier install.

  • Are LED Lights with More Diodes Brighter and Can a Trailer Backup Light be Used on a Truck
    It is pretty safe to assume that the more diodes in an LED light the brighter it will be. The only time that is not necessarily true is if one light has large diodes and the other doesn't. But any way you slice it light # BUL53CB and its 36 diodes is going to be bright. In this case, for all intents and purposes, a 4-5/16 inch and 4-1/4 inch diameter won't make a difference. The light can be used on your truck. In fact a lot of people use lights like this and other trailer lights on...

  • Replacement Round 4-1/4 Inch Grommet Mount Trailer Stop/Turn/Brake Lamps
    The closest lamp we offer to what you describe would be the Optronics # ST45RB. The lamp measures 4-1/4 inches in diameter at its largest, and the lamp installs into a 4-1/2 inch rough opening using the rubber grommet which is available separately as part # A45GB. If the 4.25 inch mounting diameter you refer to represents the diameter of the rough opening that the lamp installs in, this lamp will be a bit too large so you'd need to either enlarge the hole by 1/4 of an inch. The 3 pin plug...

  • How to Mount Optronics LED Backup Light # BUL23CB on a Trailer
    The Optronics backup light # BUL23CB, is a flush mount light. You would drill a hole 4-5/16 inches in diameter in the surface you wanted to mount the light to. You would then wire in the pig tail harness, # A49PB, to the trailer wiring. Then mount the light in the grommet, # A45GB, attach the wiring to the light and push it into the hole.

  • What Size Hole is Required to Install Optronics Grommet A45GB
    The grommet part # A45GB that you referenced requires a 4-1/2 inch diameter hole be cut to install. I looked up the light you mentioned and it is a 4 inch diameter light like what this is designed to fit. I attached an install video for you to check out as well.

  • Glo Light Trailer Tail Light Installation With Grommet
    You will install the GloLight LED Trailer Tail Light - Stop,Turn,Tail - Submersible - 21 Diodes - Round - Red Lens # STL101RB after you install the grommet # A45GB in the bumper first. This ensures the mount is in place correctly and the light will then hold firmly in place.

  • Will Optronics GloLight LED Tail Light # STL101RB and Grommet Fit 4-3/8 Inch Cutout
    The GloLight LED Trailer Tail Light # STL101RB referenced in your question, when used with the Rubber Grommet # A45GB, is designed to fit a 4-1/2 inch cutout on the trailer. Since your opening is just a tiny bit smaller at 4-3/8 inches, you should have no problem fitting the grommet on your trailer and you shouldn't have to make any additional modifications. I have attached a couple short video demonstrations on these products that you can also check out.

  • Red and White LED Trailer Lights
    We do have the lights that you need, but not necessarily in a kit. For the red you can use the Optronics LED Trailer Tail Light # STL55RB (x2) along with the Rubber Grommet for 4" Round Trailer Lights # A45GB (x2) and the 3-Wire Pigtail for Optronics Trailer Lights # A45PB (x2). For the white you can use the GloLight LED Backup Light w/ Grommet and Pigtail # BUL101CKB (x2) which includes the grommet and wiring.

  • Recommended 4 5/16" Clear Lens Light For Utility Box
    I may have an option but we do not have a matching white/clear lens light like the 4 5/16" Miro-Flex LED Trailer Tail Light # STL23RB you mentioned. The closest option we have is the ONE LED Backup Light # BUL003CB which is 4 5/16" and offers a water proof design with a clear lens and a single white LED diode. You will also need the 2-wire Connector # A49PB and Mounting Grommet # A45GB. I included a video of the ONE LED # BUL003CB for you to take a look at.

  • Replacement Round LED Trailer Tail Light for a Peterson Round Tail Light
    The Peterson part number # 420-15 that you referenced is a replacement lens for the Peterson Round Trailer Tail Light # 431800 which has a 3-3/4" diameter. Although we don't have an exact match to this in LED we do have slightly larger sizes of round tail lights that come as LED. If you are wanting to go with one from Peterson then we have the LED Trailer Light # M826R-7 which has an overall diameter of 5-1/2" but the light diameter is only 4-1/4".

  • Functions of Optronics 12 Diode Miro-Flex Tail Light # STL23RB
    The Optronics 12 Diode Miro-Flex LED Trailer Stop/Turn/Tail Light you referenced, part # STL23RB is a three function lamp. The # A47PB right angle pigtail, which is sold separately, has a white ground wire, a red wire that carries the brake and directional signal and a black wire that serves as the running light circuit. If the vehicle headlights were turned on, the lamp would be lit. Applying the brakes would make the lamp brighter. The lamp has several mounting options. It can be...

  • Availability of 24-Volt Tail Lights for Lowboy Trailer
    We do have some trailer tail lights designed to work on a 24-volt system. I recommend using light # STL23R24B. There are a few ways to mount this light. You can use a grommet and flush mount it in a 4-1/2 inch cutout using # A45GB. Or you can surface mount it with a bracket, # BK45BB. You will also use a wiring harness, # A47PB. These parts only come in red.

You could use the Optronics light, # STL23RB, # STL43RB, # STL53RCB or # STL23CCRB. These are 4 inch round lights, but they require a rubber grommet, # A45GB, that allows 4 inch round lights to flush mount in a 4-1/2 inch cutout. Lights # STL43RB and # STL53RCB are sealed, submersible lights if you are adding these lights to a boat trailer. All of these lights...

    From my research it looks like the Submersible LED Optronics Trailer Light # STL43RB is a comparable replacement light. It is 4-5/16" in diameter and has 10 super diodes that function as stop, turn, and tail signals. You can install the light using a Pigtail, like part # A45PB or part # A47PB, and a Rubber Grommet # A45GB. A sample installation video has been linked for you to use as a reference.

    The Sealed, 4 inch Round Trailer Stop, Turn and Tail Light, part # ST45RB is designed to work with a 12 V system. I have attached a product review video for this light you can check out. This light accepts the 3-prong connector like part # A45PB. The grommet used with this light is part # A45GB and is sold separately. For a 4 inch light that is designed for a 24 volt system I recommend part # STL23R24B.
