I got the round 431800 & 432000 for a 4x6 ft trailer. I had to mount them at 90 degrees from horizontal in order to light the license plate. The 432000 is designed for the license plate to be under the light. I sent an email to etrailer asking if they would let rain water in when mounted this way. They responded in about a week & said they would be fine. Well, they are not fine. Both will let rain water in when mounted this way as the drain hole is now on the side instead of bottom! I tried to caulk the holes, but caulk does not stick to the plastic. I used tape inside the housing with caulk sticking to it. Not sure how well that will work. I drilled new drain holes in the bottom. I replaced the lens screws with SS ones. I kept these only because I could not find anyone else selling them. They work, but my old ones had the clear lens welded to the housing and could be mounted anyway. These are cheap and the clear lens is snapped in with lots of gaps for water to come in. Not real happy with the results. 855114

My utility trailer was beginning to look like Johnny Cash's Cadillac. It had tail lights from boats, wrecked cars, anything that would blink or light up. I found e-trailer on line and not only did I find trailer lights but my exact original lights. The price for the lights were less than $10.00 each and arrived in less than 1 week. I am more than satisfied with your company and highly recommend e-trailer to anyone needing trailer parts. 763853

I had looked all over in my area for these trailer lights, but all trailer and automotive part outlets did not carry them anymore. A quick google and I found them right here at Etrailer.com. I ended up buying four just to make sure that I had replacements for the future. A big plus was that they were delivered two days early. Picture me with a happy face. 724683

Ask the Experts about this Peterson Trailer Lights

  • 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.

  • 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...

  • Replacement Blinker Bulb for Peterson Round Trailer Light Part Number 431800
    According to my information the replacement bulb you will need for the # 431800 is bulb number 1157. We offer this replacement on our site under # A1157B.

  • Is the Running Lamp or Brake/Turn Signal Filament in 1157 Bulb Supposed to Be Brighter
    As far as what position they occupy in the bulb, I couldn't say. Dual filament bulbs like the # 30-90-157 have two different filaments. One filament is of a different resistance value, and thus makes a brighter light. but the brake and turn signal filament would be the brighter of the two. From what you describe, it certainly sounds as if you have the brake/turn signal and running lamp wire reversed.

  • How To Wire the Peterson Round Trailer Tail Light # 431800 to a 4-Way Trailer Connector
    A 4-Way flat connector has the white wire for ground, brown wire for running lights, yellow wire for left turn and brake, and green wire for right turn and brake. The Peterson Round Trailer Tail Light, part # 431800, is a three function light and has two wires coming out of the rear. The brown wire is for running lights and the red wire is for turn signal and brake. The light is grounded to the trailer by the mounting studs on the light. The lights have to be mounted to the metal trailer...

    The Peterson Round Trailer Tail Light, part # 431800, is a three function light and has two wires coming out of the back of the assembly. The brown wire is for running lights and the red wire is for turn signal and brake lights. The light grounds to the trailer by the mounting studs which must be attached to a clean metal surface on the trailer frame. A 7-Way also has combined brake and turn signal circuits and a single running light circuit. On the trailer side connector, on the back...

  • Availability of Stud Mounted Round LED Trailer Taillight
    Unfortunately, Peterson doesn't offer an LED version of the stud mounted # 431800 lamp you mentioned. For an LED stud mount lamp, I'd recommend the Optronics # STL9RB and # STL8RB. These lamps are a bit larger, and square, but they are a stud mounted LED taillight.

  • 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...

  • Diameter of Peterson Round Trailer Tail Light
    The Peterson Trailer Tail Light - Stop, Turn, Tail - Incandescent - Round - Red Lens - Passenger Side # 431800 and driver's side # 432000 are 3-3/4 inches diameter as you can see in the attached video. The fitguide simply puts 4 inches as the closest option as they often are rounded up in size to the closest fit. We do measure each product and the specific measurements are 3-3/4" diameter x 2-5/8" deep with mounting studs 2 inches on center.

  • What is the Difference Between the Right and Left Hand Versions of Peterson Round Trailer Lights
    The difference between the Peterson Round Trailer Tail Light Right Hand # 431800 and the Peterson Round Trailer Tail Light Left Hand # 432000 is that the left side # 432000 comes with a license plate bracket and has a light to illuminate the plate. You could mount part # 432000 and 431800 on either side of the trailer, but then the license plate of your trailer may not be illuminated. You will want to check your local laws to make sure that you can mount the license plate of your trailer...

  • Can Additional Ground Wire Be Used On Peterson Round Trailer Tail Light
    You can do just exactly what you said you want to do for a ground on your Mule. The Peterson Light, part # 431800 is grounded through the mounting posts. You can run your ground wire and attach it to one of the mounting posts to make sure you get a good ground. The brown wire on the light is used for running lights and the red wire is used for brake and turn signal. You could just tape off the red wire if you just want the running light function, or wire the red wire to the brake...

  • Troubleshooting Dim Peterson Round Trailer Tail Light # 431800
    Determining the cause of your dim lamps will be a process of elimination. I would recommend using a multimeter like part # BTMT15 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...

  • Upgrading Vintage Trailer from 6 Volt to 12 Volt Lighting System
    In this case I recommend upgrading the lighting on your vintage trailer to lights designed for a 12 volt system. I have included a link to our trailer lighting for you. One of my favorites that has a vintage kind of look is the Peterson Round Trailer Tail Light, # 432000 for left hand side and # 431800 for right hand side. Unfortunately we do not offer a product that will convert the 12 volt system on your truck to a 6 volt system for your trailer.

    Yes, we have simple trailer lighting install kits that simply plug into your 4-Pole connector. For your wood chipper I would recommend the Standard Trailer Light Kit with 25 foot Wire Harness, item # TL29BK. You will not need the side marker lights included with this kit so you can just eliminate them. We also have a kit designed for cargo carriers that would work well on your wood chipper, the Draw-Tite Cargo Carrier Light Kit, item # 6504, does not include the extra side marker lights.

  • Passenger Side Tail Light to Match Peterson Round Trailer Tail Light # 432000

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.

    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.

Although we don't have an exact match to this in LED we do have slightly larger sizes of round tail lights that come as LED. If you are wanting to go with one from Peterson then we have the LED Trailer Light # M826R-7 which has an overall diameter of 5-1/2" but the light diameter is only 4-1/4".

  • 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.

  • Could Sealed, Uni-Lite Mini LED Side Marker and Clearance Light, # MCL11RKB Be Used as a Turn Signal
    You could use the Sealed, Uni-Lite Mini LED Side Marker and Clearance Light, # MCL11RKB, as a turn signal light. However, on most trailers, the brake and turn signal lights are usually on the same circuit. If you have this type of trailer, the light will light up with the brakes on. When turn signals are separate, you might want to consider an amber light, # MCL11AKB, as a turn signal. These lights would probably work well on a motorcycle trailer (a trailer towed behind a motorcycle)...

  • 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...
