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-10

Today we're taking a look at the Peterson LumenX LED trailer taillight. This oval trailer taillight serves three functions on trailers less than 80 inches wide. It provides your turn signal light, taillight and brake light, all built into one unit.Now the unit features durable surface-mount technology when it comes to the construction of the LED circuit board. It's designed to better withstand shock and vibration, and allows for improved heat distribution and an overall thinner construction. It's an LED unit, so LEDs make great replacements for incandescent lights. It's compatible with 12-volt and 24-volt systems.

It does offer a recess mount installation with a mounting grommet. Mounting grommet is sold separately. This can be mounted in any 360 degree position. On the backside for your wiring, it accepts an industry standard three-prong plug, which is also sold separately. All the sold-separately items are available at etrailer.com.It's Department of Transportation compliant.

It meets FMVSS108 requirements for automotive lighting. Taking a look at the dimensions real quick, then we'll hook it up to power so you can see what it looks like. Edge to edge going this direction, measures about 6-and-a-half inches. Edge to edge going this direction is about 2-and-a-quarter. And the overall depth of the unit, we measure from the very front of the lens to the back of the housing right here for the plug, that's 1-and-7/16ths inches deep.

Just that red lens portion measures about a half inch. And then from the front of the lens to the back of the housing right there, is about 7/8th of an inch deep.We're gonna go ahead and hook it up to power, that way you can see what it looks like. And we'll also turn off our overhead lights so you can see it in a low-light setting.So you can see here, it sends out a really nice, clear, consistent signal. This is the taillight function of the unit. When we apply the brakes, you can see how that signal output increases.

It'll do that same thing when we activate our turn signals. Now it contains a total of 10 diodes, or 10 LEDs, so the multi-diode design really helps optimize the overall light output. Input voltage is 9-volt to 32-volt DC. Product's made in the USA, and the LEDs have a limited lifetime warranty on them.That's gonna do it for today's look at the Peterson LumenX LED trailer taillight.

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. 854072
