Peterson 421 Trailer Tail Light Dimensions

Sealed, Waterproof Trailer Light

The waterproof construction of this light makes it ideal for use on trailers that may be submerged, like a boat trailer. The circuit board is sealed, which means that water will not damage the diodes or circuit board.


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 Trailer Lights - Tail Lights - 421KRUS Review

Today we're going to be taking a look at part number 421KRUS. This is the Red Flush Mounted Sealed Turn Signal Light from Peterson Trailer Lights. This light is completely sealed, the housing and the lens. It's got a shock mounted bulb. The advanced design virtually eliminates rust, corrosion and filament fracture. This is Department of Transportation compliant when mounted in either the horizontal or vertical position. A few things that it includes is the light, as well as a rubber mounting grommet, and a three wire pigtail plug. The light itself is going to give us a measurement of 6-1/2" by 2-1/4".

The overall depth is going to give us a measurement of about 2-3/8". Really simply system to use, it just goes directly into the grommet here. Then the harness back here, the three plug pigtail plugs directly into the nine locations. Snaps into place. It's going to seal up those connector points, preventing any corrosion from being able to set in. We're going to plug it up to our external power source, that way you can see what it looks like with power running to it and with our overhead lights turned off. This is going to be the tail light function.

Then when we apply the brake lights you'll see how it illuminates for a brighter signal and it also works as our turn signal as well. That's going to do it for today's review of part number 421KRUS. This is the Red Flush Mounted Sealed Turn Signal Light from Peterson Trailer Lights. .

These exact Peterson lights were installed on a B&W truck bed 21 years ago from factory. Little has changed over time. The gaskets now are a thinner rubber resulting in a sloppy fit in the hole. They should have left well enough alone. 825313

The item fit as a replacement for the original on my Tracker Tahoe boat trailer. However, you will need the connecting wiring for the replacement light due to the original plug will not plug into because of the connecting configuration. 698646

Light kit is overall a nice piece and comes with the installation mounting and wiring parts needed. My only complaint is I had one of the lamps burn out after only a few hours use but that could have been a fluke. For best service life I'd recommend upgrading to the LED kit. 615032

Ask the Experts about this Peterson Trailer Lights

  • How Does Light Assembly of Peterson Trailer Turn Signal Light # 421KRUS Uninstall
    The light assembly of the part # 421KRUS needs to come out first and then you can remove the rubber grommet. The lip on the grommet prevents it from being able to pull out when the assembly is holding that lip firmly to the cut out of the trailer. You'll want to push the light from behind the assembly out if you can access it or you might need to gently use a flat head screwdriver to pry it out.

  • Troubleshooting Malfunctioning Marker Lights on Trailer
    First, check to see if any of the other marker lights are working. If not, check that the running lights are working at the rear of the trailer, as they're all on the same circuit. If none of the running/marker lights are working, unplug the trailer and check the running light pin on the vehicle's trailer connector while the headlights are switched on, using a circuit tester like part # 40376. If you get power on the running light pin, the problem is in the trailer wiring. If it's...

  • What Size Oval Taillights Fit in Buyer's Products 337LB383ALDT Taillight Mounting Box
    The Buyer's Product # 337LB383ALDT taillight mounting box uses a standard 6-1/2 inch oval grommet mounted tallight like those included with the Optronics Fleet Trailer Taillight kit, # 337LB383ALDT. The kit includes the lamps, grommets and wiring pigtails. The lamps have 6 LED's each, and are sealed to prevent water intrusion.
