• Is there a Trailer Tail Light that Matches Peterson Back Up Light # 411SC
  We do not have an exact match for a red round tail light like the Peterson Back Up Light, # 411SC, that you have referenced that is a flange mount. The closest flange mounted lights are going to be the Peterson round tail lights # 431800 and # 432000. For a flush mounted light, you could use # 429800 which may be more what you are looking for. We also have the Optronics brand flange mounts # STL42RB or # ST47RB. They use wiring harness # A45PB.

• Are Driver and Passenger Side Peterson Trailer Tail Lights Different
  That's a good question, but different tail lights are needed for the driver and passenger side for trailers, including the Peterson lights you asked about. The reason they are marked as "Driver Side" and "Passenger Side" is because the drivers side light has a bulb underneath which illuminates the license plate, as shown in the accompanying photo. So the lights you need are: - Driver Side: Peterson Trailer Tail Light # 432000 - Passenger Side: Peterson Trailer Tail Light # 431800 I...

• Troubleshooting Dim Trailer Lamps
  Determining the cause of your dim lamps will be a process of elimination. I would recommend using a multimeter like part # PT89ZR on the circuits feeding the lamps on your trailer. You should be reading close to 12-volts at each lamp. If you are not, you will need to do some troubleshooting. Test the pins on the trailer connector on your vehicle, you should be getting close to 12-volts at each pin as its function is activated. If you see a dramatic difference in voltage between the vehicle...

• Can Peterson Round Trailer Tail Light Be Mounted Turned 90 Degrees
  The Peterson trailer tail light # 431800 does have a top and bottom, indicated on the back of the light. Normally a light does have to be mounted a certain way because otherwise the light being emitted may not be visible the way it is supposed to be as it exits the lens. But on this light I do not see that as an issue. Ideally though using an additional bracket as shown in the linked video would be the way to go. The left hand side matching light, # 432000, is a different story. It has...

• LED Replacement Light for 4 Inch Round Trailer Tail Light
  I have a solution for you. We don't have any LED lights that are a fit for the inside of that 4 inch cylinder. All of our LED options are linked and they are slightly bigger. What you can do is use an LED bulb in an incandescent fixture. For example, the Peterson Trailer Tail Light - Stop, Turn, Tail - Incandescent - Round - Red Lens - Passenger Side # 431800 in the attached video (with the 4 inch round tube) uses 1157 bulb so you can use # ARC63FR for an LED.

• Passenger Side Tail Light to Match Peterson Round Trailer Tail Light # 432000
  The passenger side of the Peterson Round Trailer Tail Light # 432000 that you referenced is part # 431800 on our site. The only difference between them is that the driver's side has the license plate light on it. If you are going to be mounting the license plate below the light you can use either the steel bracket # 428-09 or the plastic bracket # 440-09.

• Replacement Round LED Trailer Tail Light for a Peterson Round Tail Light
  The Peterson part number # 420-15 that you referenced is a replacement lens for the Peterson Round Trailer Tail Light # 431800 which has a 3-3/4" diameter.

• Installation of Replacement Trailer Lights on Boat Trailer with Multiple Ground Wires
  If a trailer is made of aluminum rather than steel it will sometimes need ground jumper wires on each light since the aluminum frame does not always provide enough conductivity. Steel frame trailers can usually do with just one main ground wire that connects between a clean bare metal spot on the frame and a wiring junction box like # 38656 where all the individual lights' grounds will join it. Junction boxes can still be used on steel frame trailers, especially when it comes time to...

• LED Replacement for Peterson 420-15 Trailer Light
  I do have an option for you but the GloLight LED Trailer Tail Light part # STL101RB most likely won't fit into the mount you have welded to your trailer. The actual outside diameter of the light is 4.25". The recessed portion behind the lens on the base is around 3.80" which I think is what you are asking for so I went out to our warehouse to confirm this for you.
