Trailer License Plate Light, Heavy Duty Armored Steel - Chrome Plated - LP21CB

Excellent product! We use these on every trailer we produce. Instead of mounting the flange on the outside we knock a hole and place the light through so the mounting flange is hidden behind the plate. Use stainless screws and nuts to secure. Because of the chrome finish this light just disappears in the diamond tread bumper plate. Easy single wire connection.

To be honest, I ordered this $3 part to fill my "shopping cart" to qualify for free shipping.
I already had an old one of these, planning to use it again on my trailer refurbishment.

CON:
- This one does not have a weatherproof rubber gasket around the hot wire exit hole like the old one. I will have to fill it with RTV silicone rubber to weatherproof it.
PROS:
- Has only one screw to retain the cap/head. My older one had two, one of which was probably redundant. This may be a con; probably should use some thread-lock compound on that single retaining screw.
- Comes with modern flat-base plug-in bulb rather than older round-base bayonet pins, for whatever that may be worth.
- Looks good, seems sturdy.

  • Why Do Some Trailer Lights Only have One Wire Run to Them
    Some trailer light assemblies like the Trailer License Plate Light part # LP21CB ground through the mounting hardware so they only need a power wire run to them. You will need to make sure this assembly is attached to a clean metal surface so that it grounds properly, If no metal surface is available you can run a wire from the installation bolt to a portion of the trailer frame to supply the ground. I attached a review video for this light for you to check out also. I also attached an...
