Very strong led light. And very multi purpose. Built a toy hauling trailer for a friend that need some extra light for loading up after dark, and liked to be able to keep a eye on his load after dark. These worked out great, also used some to light up some quads. Very bright for as small as they are. Oh and there are 26 lights on the trailer. Lol no problems with any of them. 406080

So far these led flush mount lights are working great. They're bright and a refreshing update over old incondesant lights. I got these to put on an older camper I purshased. From the photos you can see what was on the camper and I what I upgraded to. The old lights were dull and could barely tell they were lit. These lights bring a modern day update to an 1989 camper. Besides the product being good the shipping was fast and free. And I also like that on etrailers site when your package is in shipment they have a map of the US showing where your package is. 425483

A couple of years ago, I converted a single jet-ski trailer to a kayak trailer to hold my two kayaks, and installed new LED stop/turn/brake lights and clearance lights from etrailer.com. The lights worked great, and I used the trailer for a couple of years before I realized that I was missing a light for the license plate! I'm surprised I never got pulled over by the police! etrailer.com came to my rescue again with this great LPL31CB license plate light. It's very bright and really lights up the plate and the ground around the back of my trailer. Recently I added three more small red clearance lights at the back of my trailer, so the tailgaters and crazy drivers have no excuse about seeing my trailer! See the pictures! etrailer.com has great products, great service, and fast shipping! 327358

Bought 1 to replace a broken lens, then realized they have changed since 1993, so bought 3 more to replace the rest. Excellent lenses that are built a lot tougher than the original in 1993. Great shipping response. I'LL BE BACK I'm sure. 681436

Products were delivered on time in a package that had good protection. The lights are constructed of metal and are of good quality. I'm pleased with the lights. Will update with pictures when I get them installed. 671878

The light is working great. Since it has a very low amp draw, I wired it to my steps on the trailer and installed down by the steps a waterproof switch. It works great as a night light and to see after dark when going up the stairs. We already had outside led lights, but they are much brighter than needed. 662786

A year later this light still works perfectly. This was the last light on my trailer to change over to led. The leds always work and etrailer sells high quality products and is my go to place for all trailer needs! 640801

- LPL31CB
by:

Yes, the light is working good. I mounted it just above and on the right side of our entry stairs on our travel trailer and put an off/on switch near by. The regular outside light is an LED and rather bright. This uses very little electricity and is just enough light for the stairs and for a night light when returning after dark. 600809

Ask the Experts about this Optronics Trailer Lights

  • Installing Optronics LED License Plate Light # LPL31CB
    Trailers are usually wired so that the brown wire carries the running light circuit. The wire color on the wiring system of a vehicle can vary. You can easily find the correct circuit by turning the vehicle running lamps on and then using a circuit tester like part # 40376 to test the wires feeding the taillight assembly until you find the wire that shows current. The # LPL31CB lamp has two wire leads, one would tap into the running light circuit, the other would tap into an existing ground...

  • How Many Trailer License Plate Lights are Required On a Trailer
    You should only need one license plate light like the part # LPL31CB to be legal as long as it properly illuminates your license plate. I attached a couple review videos for this light plus a help article on trailer lighting requirements for you to check out as well.

  • Can Optronics LED Mini License Plate Light # LPL31CB Mount Upside Down Without Water Leakage
    The light you referenced, Optronics LED Mini License Plate Light # LPL31CB, is intended to mount so that its chrome-finish cover is on top. Although it does have a weathertight seal against the elements, this is intended to provide protection from water damage in the usual mounting position. I recommend one of the lights shown on the linked page since these products are all submersible. None of these happens to be an LED-type however. Optronics # LP91CB can be used along with their...

  • Steel Frame License Plate Bracket Availability that is Compatible with LED License Plate Light
    If you dont mind drilling a few holes you could get the LED Mini Trailer License Plate Light # LPL31CB to work with a Steel Trailer License Plate Mount Bracket # LP20SB. But I pulled both these products from our warehouse and the holes of these products do not line up, but if you used the # LPL31CB as a template you could drill the correct dimension holes in the # LP20SB above its current holes. Or you could check out the Optronics Heavy Duty License Plate Bracket # LP15SB. This has...

  • Finding Wire for Adding License Plate Light on Motorcycle
    Finding a running light wire on trailer wiring for adding a license plate light typically is a matter or tapping into the running light circuit on trailer wiring. While we do have install videos on trailers we don't typically do them on motorcycles for trailer wiring as that's not what these were designed for. And we don't get a lot of requests here to install trailer lighting on motorcycles. The best solution I can recommend would be to trace the wiring that runs to the running light...

  • What Size are the Mounting Holes for LED Mini Trailer License Plate Light # LPL31CB
    I went out to the warehouse and pulled LED Mini Trailer License Plate Light # LPL31CB to take some measurements for you. This light does include some screws to mount it. The screw holes are approximately 3/16 inches in diameter. I made a video for you showing the dimensions for you. The wires coming out of the back are coming out of a couple of round nubs. The overall dimensions of the nubs (the hole size to cut if needed) would need to be 1/2 inch across by 1/4 inch tall.

  • Recommendations for a Vehicle with all Blinkers Converted to LEDs
    There are work arounds that allow you to install LEDs in the place of blinker bulbs. For example you can install a load resistor like our Putco LED Light Bulb Load-Resistor Kit # P230004A on each light assembly that will blink with the turn signals. However, since you plan on replacing all your blinkers with LEDs I thing you would be better off going to an electronic flasher relay to replace the thermal one in your vehicle. Currently none of the LED lights we offer have pre-installed...

  • Dimensions and Recommended Mounting Hardware for the LED Mini Trailer License Plate Light
    The LED Mini Trailer License Plate Light # LPL31CB comes with installation screws, but if needed you could install it with other hardware. You might find that a self-tapping screw would work better if you plan on installing this to a metal surface. The distance on center between the mounting holes is 2 inches. The diameter of the holes is 3/16 of an inch. And the thickness at the mounting holes is an 1/8 of an inch.

  • Replacement License Plate Light For 2009 Haulmark 7x12 Low Hauler Trailer
    I did some research on your 2009 Haulmark Low Hauler trailer. I was able to see several different styles of license plate lights and holders on trailers. I have attached a link to our product page for license plate lights. Some have the license plate holder attached to the assembly and some are just the lights that are mounted to light the license plate. There are different opinions about mixing LED and incandescent lights on the same circuit. We have had customers that wire them in the...

  • Recommended Metal License Plate Bracket with Light
    For a metal license plate bracket with light, we have the Peterson License Plate Light with Bracket # PM436B. We have other options with lights but they are a polymer. You can always get the parts separately like bracket # LP20SB, # CE26053A or # LP15SB and then add the light # LPL31CB. I've attached a link to your light options.

  • Instructions for Wiring Additional License Plate Light With Submersible Trailer Light Kit # TL5RK
    When it comes to adding an additional license plate light to the Submersible, Under 80" Trailer Light Kit with 25' Wiring Harness, # TL5RK, I recommend taking a look at the LED Mini Trailer License Plate Light, # LPL31CB.

In order to wire this light, one of the wires will need to connected/spliced into the running light circuit (brown...

  • Is the Bargman Surface Mount LED Double Tail Light Available with an Integrated License Plate Light
    At this time there is not a version of the Bargman LED, Surface Mount, Double Tail Light, # 47-84-610, that incorporates a license plate light at the bottom of the housing. We do have a solution for you though. You could install the Bargman lights that you like and then install an LED license plate light like the LED Heavy Duty Trailer License Plate Light, # LPL41CB, or the LED Mini Trailer License Plate Light, # LPL31CB, above your license plate. If you need a bracket to attach the...

  • Do Tail Lights on GearDeck 17 Enclosed Cargo Carrier # H00604 have a License Plate Light
    I went out to our demo area and personally checked the lights on the GearDeck 17 Enclosed Cargo Carrier # H00604. While there isn't a specific white light that shines down on the license plate the red lights for the other functions do illuminate that area slightly so the license plate would not be complete in the dark at night. For greater visibility you could splice in an LED license plate light, # LPL31CB, and be in compliance for sure.

  • Could LED Mini Utility Light be Used as License Plate Light
    You said your license plate mount bracket is recessed so as long as the light part # UCL13C2PG can be mounted pointing down towards the plate it would work well for you. If you were to mount it on the same vertical wall as where the license plate is the light would be directed towards the back of the trailer and would not work well. If you need something to mount directly over the plate you would need the part # LPL31CB.

  • Recommended Tail Lights And LED License Plat Light
    The Bargman Triple, Long Tail Light - 84, 85 Series - Red, Amber LED; Incandescent Backup - Black Base # 47-84-104 is a recessed light and doesn't have a license plate light. There is nothing with this style or size that does. I recommend using a separate light like the LED Mini Trailer License Plate Light, 2 Diode - Chrome Plated # LPL31CB for this. You can also use a frame and LED combination like the LED Trailer License-Plate Light w/ Mounting Bracket, 2 Wire, 5 Diode - Clear # LPL55CB.

  • License Plate Recommendation for a Small Trailer Towed by Motorcycle
    Most likely yes, but you would have to check with your local DOT to confirm that. An easy light to use would be the part # LPL31CB. This would tie into the running light circuit of the trailer's lights and would light up the license plate.
