Expert Answers about Trailer Lights


  • How Many Light Functions Does the Pedestal Mount Dual Face Trailer Light ST52RB Have
  • The Pedestal Mount, Dual Face Trailer Parking and Turn Light, part # ST52RB, is not a 3 function light like the Pedestal Mount Trailer Stop, Turn and Tail Light, part # ST51RB. You would not want a dual faced light as a stoplight as the brake lights should only be visible from the rear of the vehicle.

  • Are All Replacement Oval Trailer Tail Lights the Same Size
  • Since trailers come in different sizes and lights are used for different things, not all oval trailer lights are the same size. For example, the Optronics Trailer Tail Light # STL68RB is 10" Long x 3" Wide whereas the Optronics Trailer Tail Light # STL211RB is 6-1/2" Long x 2-1/2" Wide. I have linked our selection of oval trailer lights for you to filter through. You can choose different options to filter through like size, color, and whether it is LED or incandescent.

  • Troubleshooting Weak Trailer Wiring with Dim Lighting
  • If all of the lights are dim on your trailer wiring that would indicate to me that it's not grounding properly to allow the lights to function. First thing to check would be the main ground wire of the trailer's wiring harness. Make sure it's connected to a clean metal surface on the trailer frame. You can also run jumper wires from the ground wires of the light assemblies back to this circuit to improve the ground as well. I attached a help article on trailer wiring troubleshooting for...

  • How Many Functions Can the 7 inch Round Transit Stop and Tail Light # ST90RB Do
  • This 7 inch Round Transit Stop and Tail Light # ST90RB can do stop and turn signals when used on a combined stop/turn circuit, but it cannot do taillight functions as well. The closest thing to a 7 inch 3 function trailer light we have is the 4-3/8 inch Round Trailer Tail Light, Stud Mount, 3-Function Trailer Light # ST24RB. However, this light is only 4-3/8 inches in diameter.

  • Is the Optronics LED Trailer Tail Light item # STL78RB DOT Approved?
  • Since the Optronics LED Trailer Tail Light item # STL78RB is red it can be used as a third brake light. This light is DOT approved and can also be used as a rear turn signal. To use it only as a third brake light you will want to wire the black tail light wire and the red stop/turn light wire to one circuit. The white wire is ground. If you are needing to add a turn signal on the side of your trailer you will want to use an amber light like the item # STL78AB. I have linked a review video...

  • What Gauge Wire Would be Required for Trailer with LED Clearance Lights that Draw 3.3 Amps
  • Even thought that is a quite a few LED lights on your trailer the amount of amperage draw total for all circuit would be 3.35 amps. That's well below what standard lights would draw on trailers with just a handful of incandescent lights. You would easily be able to get away with 14 gauge or even 16 gauge wire.

  • Will The Peterson M540 Light Kit Fit A Bracket With 2-1/4" of Head Room?
  • I measured from the center of the mounting studs to the top of the lights that come with the Peterson Light Kit # M540 and it is 2-1/2". Just to make sure, I also measure the Optronics Under 80" Trailer Light Kit with 25' Wiring Harness # TL5RK the same way, and they measure exactly the same, unfortunately. With that said, I may have another option available, but the lights will be completely different. If you look at the Optronics Trailer Light Kit # TL16RK, which technically is for trailers...

  • What Size Diameter Hole Is Needed to Install Optronics Trailer Light # MCL50AB
  • To install the Optronics Trailer Light, part # MCL50AB, you will need to use 2 Inch Round Grommet, part # A54GB. The mounting hole to properly install the light # MCL50AB with the grommet should be 2-5/16 inches in diameter. This light uses a 2-wire plug, like the Two Wire Pigtail, part # A46PB.

  • What Does it Mean when a Trailer Light is Listed as Waterproof or Submersible
  • When it comes to trailer taillights the terms waterproof and submersible are somewhat interchangeable. If a taillight is considered submersible that means that the internal circuits are waterproof and would be protected for if you were to back the trailer into water like when launching a boat. The part # TLL56RK that you referenced is listed as waterproof and submersible so it would work great on a boat trailer. Lights that aren't waterproof or submersible will still work just fine on...

  • Is There a Replacement Lens for Optronics Trailer Clearance Light MC48RB
  • The Optronics Trailer Clearance or Side Marker Light # MC48RB does not have a replacement red lens; if you have this light and the lens was damaged you will need to replace the entire unit. This is an incandescent light and I recommend upgrading to an LED if you do need to replace the light because LED lights are brighter, last longer and will not draw as much power as their incandescent counterparts. The Optronics LED Trailer Clearance or Side Marker Light # MCL32RBB is a great option...

  • How Waterproof is the Over 80" Wide, Square LED Trailer Tail Light # STL2RB
  • The Over 80" Wide, Square LED Trailer Tail Light # STL2RB that you referenced is designed to be a submersible light. What that means is that once you got to the boat ramp you would want to disconnect your trailer wiring from your tow vehicle and then you could back your boat trailer into the water and the lights will be totally fine. The LEDs are sealed so that water would not get to them. This light would be exactly what you need. For the left hand side you would want part # STL3RB.
