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 Checking Out the Peterson LumenX LED Back-Up Light for Truck or Trailer

Today we're taking a look at a Peterson Luminex LED backup light. This oval light functions as a backup light for your trailer work truck. It features durable surface mount technology when it comes to the construction of the led circuit board. That design better withstands shock and vibration and allows for improved heat distribution in a thinner construction.It is an LED system. LEDs make great replacements for incandescent lights. They last longer, they burn brighter, they're much more efficient.

With LEDs, you don't have to worry about replacing bulbs or worry about brittle filaments. It does feature a sealed design, so it is protected from the elements. It's a recessed mount installation with a mounting grommet and it also accepts an industry standard two prong plug.Both of those items, the grommet and the plugs are sold separately and available at etrailer.com. It is Department of Transportation compliant. It meets FMVSS 108 requirements for automotive lighting.

And the product's made in the USA. When it comes to the measurements of the light, we'll look at those real quick and then we'll hook it up to power.Edge to edge going this direction. It's about six and a half inches. Edge to edge going this direction. It's about two and one quarter inches.

All right, we'll go and hook it up to power. That way you can see what it looks like with some power running to it. We'll also turn off our overhead lights so you can see it in a low light setting.So when the reverse function is activated, you can see how this will eliminate, sends out a very bright, clear, consistent signal. We're looking at seven white LEDs with a clear lens, so it allows plenty of light to come through. And then the multi diode design really helps optimize the overall light output.

The input voltage for this unit is rated for nine volt to 16 volt DC. That's going to do it for today's look at the Peterson Luminex LED backup light.

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:

Worked great as a replacement for reverse light on my flat bed truck



by:

As described and fits perfectly into existing holder

by:

I replaced the entire running lights system and the LED lights are high quality and work great.
The running lights and backup lights are all amazingly bright!
I really appreciate that they help keep my trailer visible and safe!



by:

The installation was done without problem and the lights worked as expected.



by:

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.



by:

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



by:

The lights look ok, but I haven't gotten them installed yet. My main complaint is the packaging, because everything I ordered was thrown loose into one box. You need to do better to ensure nothing is damaged during shipping.

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:

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:

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:

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:

Easy installation. Working perfectly after 1year



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:

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:

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



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.
