Features to know about

Reliable License Plate Lighting: Compact and Bright Incandescent Design

This small but effective light keeps your license plate clearly visible. Measuring 2-9/16" long by 1-1/4" wide, it uses a single 194 bulb behind a clear lens to provide bright, even light when properly mounted. It runs on 12V DC power and draws only 0.261 amps at 12.8V, making it efficient for continuous use without putting a strain on your electrical system.

Built to Last: Durable Chrome-Plated Housing

You won’t have to worry about rust or fading here. The chrome-plated housing is tough, giving the light a clean look that holds up over time. It’s designed to stand up to outdoor conditions while keeping its shine, so your setup stays neat and professional-looking.

Weather Protection Where It Counts: Foam Gasket Seal

Water infiltration can quickly ruin a light, but this one has a foam gasket that helps create a weathertight seal. When installed correctly, it helps block out moisture and dirt from getting into the housing or wiring connection, so the light stays reliable even in wet conditions.

Straightforward Mounting: Surface Mount with Two Wires

Installation is simple thanks to the surface-mount design and standard 2" center-to-center mounting holes. The 2-wire setup includes one power lead and one ground wire, so wiring is quick and clear. Just use up to 1/4" screws (hardware not included) to secure it in place, connect the wires, and it’s ready to go.

Certified for Road Use: DOT Approved Replacement Fit

This light meets DOT requirements after testing for compliance, giving you peace of mind that it’s built for legal road use. It also matches several common part numbers—Uni Bond #DL2020, Grote #60151, and Peterson #M434—making it an exact replacement option when you need a dependable update without modification.

Perfect for my application to light license plate from two sides on home-built teardrop trailer. Still working after over 11,000 miles of travel.



by:

Used these as replacement license plate lights for my 1976 BMW 2002 restoration. The originals, when available, are running $50+ each, and these lights are a very close match in style and fitment at a fraction of the price. They also appear to be well made - chromed metal where BMW used plastic.



by:

Great price,quality product and great shipping time.

Very good.



by:

We had bought a replacement bumper for our truck, it came with a new license plate light, but it was only the hot wire, it was supposed to ground(?) to the powder coated bumper or attach a ground wire to it since the old light was too big for the hole. This light is a great option, we'll have to drill a couple small holes, but a much better alternative. The light itself is very well made & looks easy to replace the bulb.



by:

Perfect for illuminating the trailer plate after moving it to the gate.



by:

Works as designed

License plate light works great
