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 Review of Peterson Trailer Lights - Tail Lights - M821R-7

Today we're taking a look at the Peterson LumenX LED Trailer Tail Light and this is an oval trailer tail light that serves your trailer three functions. With this you'll get a turn signal light, a tail light, and a brake light, all built into one unit. It features durable surface-mount technology when it comes to the construction of the LED circuit board. That design better withstand shock and vibration and allows for improved heat distribution and an overall thinner construction.Now it is an LED light. LEDs make great replacement for incandescent lights, they last longer, burn brighter, and they're more efficient. With LEDs you don't have to worry about replacing bulbs and you don't have to worry about brittle filaments.

It is a recessed mount installation with a grommet that mounts in a hole with a grommet and a pig tail wiring harness. Those items are sold separately and available at etrailer.com. You can mount this in any 360 degree position.Here on the back you'll notice the port for a 3-prong plugs so it accepts an industry standard 3-prong plugs which again your grommet and plug are sold separately. It is Department of Transportation compliant. It meets FMVSS 108 requirements for automotive lighting.

Parts are made in USA. Taking a look at the overall dimension real quick and I'll hook up the power so you can see what it looks like with some power running to it.Edge to edge going this direction is about six and a half inches long. Edge to edge going this direction is about two and one quarter inches. And then the depth of the unit just measuring that lens, that red portion, is about a half inch. Front to back of the housing measures about seven eight of an inch deep.

And the overall depth from the very front to the back of the port right here for the plug is about one seven sixteenth inches deep.It contains a total of seven LEDs or seven diodes. The input voltage is nine volt to 16 volt DC. We're gonna go and hook it up to power that we can see what it looks like with power running to it. We'll also turn off overhead lights so you can see it in a low light setting.So here you can see it sends out a really nice, clear, consistent signal. This is the tail light function of the unit.

When we apply the brakes, you can see how that signal output increases, and it'll do that same thing when we activate our turn signals.Again, seven diodes so the multi diode design really helps optimize the overall light output. Parts are made in USA and LEDs have limited lifetime warranty on them. That's gonna do it for today's look at the Peterson LumenX LED Trailer Tail 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:

Tail lights were as advertised and shipping was timely.



by:

They work fine but we’re just thrown in a box with no packaging or anything! But appear to be not damaged.
For $[XX] some dollars I guess I expected a little more care on the packaging end



by:

easy to install, bright and looks great.



by:

Fast shipping and great price will deal again

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.

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:

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:

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:

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 installation. Working perfectly after 1year



by:

Thank you for the prompt service.



by:

These worked great



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:

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.
