Recessed-Mount Light

Recessed Grommet Mount Trailer Light Installation Diagram

Recessed-mount trailer lights install with a grommet, which is often sold separately. These lights extend past the trailer surface and require a hole for installation. If replacing a light, you can utilize the pre-existing hole. If installing a new light, you will need to cut a hole or use a mounting bracket (sold separately) to complete the installation.

Video Transcript for Peterson LumenX LED Trailer Tail Light Installation - Big Tex Trailer

What's up, everybody It's AJ with etrailer.com. Today, we're gonna be checking out this LumenX tail light, so it's gonna be a good replacement or an upgrade for your trailer. Today, we're gonna be installing it on our Big Tex flatbed trailer behind me. Now, this is already gonna be an upgrade from the existing light because of the extra diodes. This one's gonna have 10, when the light that was on the trailer only had six. So this is gonna help brighten that up quite a bit.

We're gonna have the old one. You see it has some wear and tear on it with the six diodes. This is the new one that's gonna have 10. Now, it also has a polycarbonate lens on there. It's gonna be a red lens with white LEDs on the inside, so the cover's gonna hold up to some damage.

It's not gonna break very easily. Also, DOT compliant, and can be fully submerged in water and won't cause any issues. Now, we're gonna hook it up to the trailer. So we have the three prong hookup, which is the industry standard. Let's push that into place.

With that connected and pushed in place, now we just push the light here in the grommet. It's not that hard to do. We just push in on the light, and it fits right in there. Here's gonna be the brake lights. Left turn.

And tail lights. With the lights on, you can definitely see a difference. You have the 10 diodes in the newer light being way brighter than the old six ones here. So you definitely get more brightness with these lights. Now, you also get all the functions you did with the regular tail lights. So it'll still be a tail light, brake light, and even a turn signal. So the tail light's gonna measure up to six and 1/2 inches by two and 1/4 inches wide. So just keep that in mind. Go out to your trailer and measure it, so that way you can get the right light for the right trailer. Overall, it's a definite upgrade on your trailer. You can see the difference right by side by side even if it's still LED and LED. The extra diodes are gonna brighten it up. Now, if you're going from incandescent to LED, it's a major upgrade because you're not gonna have to worry about that light for a long time. The incandescent is gonna burn out way sooner, and you don't have to deal with bulbs. This one is gonna last longer and be brighter overall. Well, I think that does it. Thanks for hanging out, and I hope this helped.

This is a review of etrailer as the product is 4*. The lights came loose in a box so all 4 lights lenses are scratched. When you spend 16-21$ a light you expect them to handle with care but they don’t.

Great product. Did not listen to my salesperson Jesse. I do need the 2 prong adapters.

Purchased these in April, installed in May. Second trip I made with the trailer in July, the lens fell off one light. No damage, it just fell off.
Neither E-trailer, nor Peterson will warranty the light.
I think it's the last time I spend money with either of them.



by:

Exactly what you'd expect. Seems to be a good quality grommet-mount LED light. I used it for a mid-ship marker on a gooseneck.



by:

Two of the three lights I installed randomly turn themselves off. At times they also require multiple “touches” to operate, which can get frustrating.



by:

The light is very bright and is good quality I love it



by:

Good product, nice bright led's
Should
last a long time. Great customer service and good website description of product. Etrailer has always been a great company to deal with. Keep up the good work.



by:

perfect timing on the ETA of parts Thanks alot



by:

Very nice looking lights. Disappointed in that I did not watch the video to see that a harness is needed to wire the lights. I will get them with next order though.



by:

Bought 4 tail lights only 1 worked right out of the box - had to work with the other 3 to get them to work



by:

Exactly what we were looking for. I do think the description needs to be more clear as I ordered an extra wire that actual came with the light. Other than that received the product earlier than expected and we were able to finish the job for the customer sooner.



by:

Easy installation. Working perfectly after 1year



by:

I was worried that the backup lights would not be bright enough, but they’re surprisingly bright for only one segment of the light.



by:

Easy instillation and very bright. But you must be very thorough that you have the right sized grommet for the hole in the bed or trailer AND for the light you are using. Not all grommets are the same as with trailers and flat beds so make sure that you double check the hole size both ways of the bed and the light to minimize head aches when you go to install.



by:

I used these to replace the tail lights on my utility trailer. They are bright and because they are LED they will not require any attention. I look forward to many years of reliable service.



by:

Thank you for the prompt service.



by:

These worked great



by:

Perfect replacement for my damaged tail light on our new Timpte 720 aluminum car hauler. Shipping was very quick and packaging was perfect. Thank you for the great service.



by:

Great light but would need to manually turn them on each time you kill the main switch in the horse trailer. Will reorder the same light but without the touch switch in the middle of the lens. Bad on me for being a poor electrician.



by:

Sure would’ve been nice to know the mounting flange and enclosure is plastic.... not one place in the description or video.... disappointed

  • Parts Needed to Install the 6-1/2" Oval LumenX LED Trailer Tail Light
    The LumenX LED Trailer Tail Light # M821R-10 has a pretty simple installation so you just need a grommet and a pigtail wiring with the industry standard 3-prong connector to complete the install. If this is a replacement then you likely already have these on your trailer, but if not these are the parts you need: - PVC Grommet # a70gb - Pigtail Wiring # A45PB (No Angle) OR # A47PB (Right Angle) The correct pigtail style really just boils down to what kind of spacing you have behind the...
