• Peterson Combination Trailer Tail Light - Can Incandescent Bulbs Be Replaced With LED Bulbs?
  Hello Gregg; yes, the incandescent bulbs in the Peterson Combination Trailer Tail Light # 432400 can be swapped out for LED bulbs. This light uses an 1157 bulb for the tail light and an 1156 bulb for the turn signal. Here is what I recommend for bulbs: - 1157 LED Bulbs - 360 Degree - Double Contact Bayonet - 600 Lumens - White - Qty 2 # ARC93FR - 1141/1156 LED Bulb - Single Contact Bayonet - 360 Degree - 210 Lumens - Cool White - Qty 2 # DI85VR While replacing the bulbs is possible,...

• Troubleshooting Peterson Tail Lights on Boat Trailer That Keep Burning Out
  It really all depends on what trailer light kit you have installed on your boat trailer. Some kits are designed to withstand submersion and other kits aren't. If you can let me know what kit is on your trailer (not just the type of bulbs you use) I can help you determine if it is submersible (granted we carry it). Another thing to note is that you need to make sure your trailer wiring is unplugged before backing the trailer into the water. Even if your lights are submersible, if you don't...

• Adapter for Mercedes Benz ML 350 Towing Trailer With LEDs to Prevent Hyper Flash
  German vehicles really don't like towing trailers that have LED taillights unfortunately since the amperage is so low but we do have a solution for this with the # C57003 for if your trailer has a 7-way or the part # C35FR for if it has a 4-way. These adapters have load resistors in them which allows your vehicle to think a trailer is connected that draws more amperage and gets rid of the hyper-flash issue you have.

• Recommended Replacement Clearance Lights With Only Wire
  It's normal for some clearance lights to ground through the mounting screw instead of running an extra wire so there's nothing wrong with that. For the amber clearance lights you can use part # MCL67AB and for the red part # MCL67RB. These both come with a single wire for power and ground the the bracket mount screw and are 4-1/8" long x 1-1/4" tall x 1-3/16" deep.

• How To Install The Peterson Square Trailer Tail Light Part # 432400
  I am assuming you are referring to the Peterson Square Trailer Tail Light part # 432400. If this is the case, on the back of the taillight assembly, there are 4 wire holes for each function located at the top of the tail light assembly. The top two holes are designed for a larger gauge wire whereas the bottom two are designed for a smaller gauge wire. In order to remove the old wires, you will first need to unhook the trailer connector from the vehicle. You can then insert a small screwdriver...

• How Does Wiring Run to the Peterson Trailer Light part # 432400
  Essentially what you said is how you run wire to the part # 432400. It's a pretty strange method I will agree, but basically you just insert the wires into the holes on the back of the light assemblies and they socket grabs the wire. If you fast-forward to the 2:30 section of the video I attached you will see our installer use this method. It's really pretty nice since you don't have to splice anything or use any soldering. If you do pull hard enough you would be able to remove the wire,...

• Trailer Tail Light Recommendation that Needs Mounting Studs that are 2-1/2 inches Long
  None of the stud mounted trailer taillights are going to have studs that are 2-1/2 inches in length. What you could do is get a Aero Pro Submersible LED Trailer Tail and License Light # STL37RB and then swap out the carriage bolts that come with it for longer ones that would fit your trailer. The matching other right hand light would be # STL36RB.

• Recommended Trailer 4-Way Wiring Harness For a 6' X 12' Utility Trailer
  I recommend the Hopkins Endurance 4-Way Flat Trailer Wiring Harness # HM48265. This harness uses a wishbone design so that you will have conductors for your running lights and tail lights that run down each side of your utility trailer. Since your Side Marker Trailer Lights # MC35AEB, Peterson Tail Lights # 432400 and Peterson Identification Light Bar # 428100 are designed to ground on the frame this harness also uses a frame mounted ground. The entire harness is 30' long ensuring you will...

• Replacing Bulb on Peterson Square Trailer Tail Light # 432400
  To change the bulbs in Peterson trailer tail light # 432400 you will first remove the main lens which is held on by 4 screws. The main bulb can be removed by pushing down and rotating the bulb counterclockwise. There is a diagram on the inside of the case that explains this and it says turn it 30 degrees then pull up. I had to turn it several more times when I played with the light so it probably varies slightly. To install a new 1157 bulb # 30-90-157 you will line up the lower nub on...

• How to Wire a Trailer Light with 1 Wire
  It sounds like the light on your trailer is either missing a wire or it was only designated for one tail light function. If the light does not look old or damaged, I would guess that it is just a clearance light and should be connected to the running light circuit. If this is the case, it should not function as a brake light as well because it was not designed to do so. The brake lights and tail lights run on different circuits and they were not designed to connect to the same wire on a...

• Availability of Command Replacement Brake Lens off 1999 Gulfstream Ultra C-Class Motorhome
  Thank you for including a photo; it's always a huge help! I may have a solution for you, but I'm not seeing anything we have as far as replacement lenses that would would for this Command Electronics tail light on your 1999 Gulfstream Class C. Additionally I'm not seeing anything close to your light as an available replacement from Command, so it might be discontinued and the light would need to be replaced completely. If that ends up being the case we do have some options that are...

• Single Wire ID Light Bar for a Boat Trailer Over 80 Inches Wide
  Your old ID bar must have grounded through its mounting hardware since it only had the one wire. ID bar # MCL97RB also has just one wire and grounds through the mounting hardware. This is an LED light so it will draw much less power than incandescent lights. If your boat trailer is aluminum though a jumper ground wire should be attached between the frame and mounting hardware and attached to a steel surface or the main trailer connector ground. A ground issue is why the other light was...

• Troubleshooting Peterson 440 Trailer Tail Lights Stop/Turn Signals Not Working
  It sounds like the ground is not your issue on the Peterson Tail Lights # 432400 & # 432200 since your running lights are both working. You will want to start by testing the power using a Test Light # PTW2993 to ensure you are getting power to the tail lights. This will help you to determine if you need to identify why power is not getting to the lights or if it could be a bulb/ground issue.

• Replacement Tail Light Cover Needed for a Peterson 440 Trailer Tail Light
  The Peterson DOT AIST 90 that you referenced has to do with how the light was tested, but I do know what light you are talking about. It is commonly known as a Peterson 440 light and we have them listed as part # 432200 for the right hand (passenger) side and part # 432400 for the left hand (driver) side. The only real difference between these 2 parts is that the driver's side light has a clear piece below it that illuminates your license plate. The red lens cover for both lights is part...

• Differences Between Peterson 432200 6-Function and 432400 7-Function Trailer Taillights
  The driver's side lamp, part # 432400 has an additional function that the # 432200 passenger side lamp does not. The driver's side features a clear lens on the underside of the lamp housing that would illuminate a license plate mounted underneath it. I've provided a photo showing the difference. You would indeed want to purchase one of each. I've linked to a product video featuring both taillights.
