P2-Rated Lights

Diagram of light spread for P2 rated light

A P2-rated light produces a 45-degree angle of light to either side of its centerline for a total of 90 degrees of coverage. This beam pattern can be seen straight on, but it cannot be seen clearly from the side. So this type of light can be used as either a side marker light or a clearance light, but it cannot function as both. If you need both functions, then you must install 2 separate lights on your trailer - one as a front or rear clearance light and one as a side marker light.


Surface-Mount Light

Surface Mount Trailer Light Installation Diagram

Surface-mount trailer lights install using a flange or bracket with mounting holes. These lights lay flat against the trailer surface and only require a small, often pre-existing hole, for wiring. Mounting hardware is used to secure the light to the trailer.

  • Replacement Clearance Lights Needed for GLO-BRITE 122R and 122Y Lights
    From what I could find it looks like your 122R (red) and 122Y (amber) lights measure 3.75" x 1.70" x .81". We don't have any replacement lense directly for the GLO-BRITE lights but we do have some similar lights that you could use as replacements. I recommend checking out the Command LED lights # 328-K-51 for amber and # 328-K-52 for red. These measure 4" long x 1-1/2" tall and have mounting holes that are spaced 3" apart on center. Attached are links to review videos and our selection...

  • Replacement Trailer Taillight for Part Number cl-44120-ab
    Hey Daniel, we don't carry that exact light fixture but I would say our most similar option is the Miro-Flex part # MCL17AB which is a little smaller and has a similar bolt pattern.

  • Replacement Side Marker Light for 2013 Forest River Sunseeker
    Hi Derrick; we have some similar lights but we do not have an exact match to the CL-44120-AB with mounting holes 3" apart on center. The closest options are the LED Clearance or Side Marker # MCL0030ABB or the # 328-K-51. The # MCL0030ABB is 3-3/4" long x 1-13/16" tall x 3/8" deep with 2-11/16" between mounting holes. The # 328-K-51 is 4" long x 1-1/2" tall x 1/2" deep and with a distance of 2-1/2" between the mounting holes. Both will work but will require drilling an extra hole which...

  • Recommended Marker Light To Replace Glo-Brite 122
    I have a replacement light option for you, but we do not offer a replacement lens for the Glo-Brite 122 at this time. The closest replacement option is the LED Trailer Clearance or Side Marker Light with Reflex Reflector - 2 Diodes - Red Lens # 328-K-52 if you are needing a red light, or # 328-K-51 if you are needing an amber light. Both of these options measure 4" long x 1-1/2" tall and have mounting holes that are 3" apart on center as shown in the included diagram. I included videos...

  • Replacement Clearance Light for Glo Brite 122Y on 2013 Forest River Sunseeker
    We have some replacement clearance lights that are similar to the Glo-Brite lights, but unfortunately we do not carry Glo-Brite brand, and from what I understand they have gone out of business, so I do not have the exact lens covers that you are looking for. For a replacement clearance light for your 2013 Sunseeker, I recommend the Command Electronics LED Trailer Clearance or Side Marker Light with Reflex Reflector # # 328-K-51 because they are a similar size to your current clearance...

  • Replacement LED Top Command Clearance Light With SAE-AP2-16 On Lens For 2018 Sunseeker Motorhome
    You will need the Red LED Trailer Clearance or Side Marker Light # 328-K-52 or Amber LED Trailer Clearance or Side Marker Light # 328-K-51 for your 2018 Forest River Sunseeker motorhome. These lenses have the same Top Command SAE-AP2-16 markings on the lens.

  • Is There a Replacement Lens for Winnebago 147680-02-01A (Glo-Brite 122Y) Amber Marker Light
    I do have an option for you but the Winnebago 147680-02-01A (Glo-Brite 122Y) is discontinued and no longer available. Therefore, you'll have no other option but to replace the light entirely but not to worry, this is actually very simple. I recommend the LED Trailer Clearance or Side Marker Light with Reflex Reflector part # 328-K-51 which is an LED upgrade and installs easily with two wires. Basically, you'll put off the old lens cover for the light you want to replace, remove the screws...

  • Recommended Red and Amber LED Clearance Lights For 2017 Entergra Coach Aspire Motorhome
    I would be happy to help! To add clearance lights to your 2017 Entegra Coach Aspire Motorhome I recommend the Red # 328-K-52 and Amber # 328-K-51. These are two diode LED lights like you were wanting, and install by surface mounting to your motor. Based on the pictures I was able to find of your motorhome it looks like it has some oval lights, so these will blend in and not look out of place. You will need to use # 16-1-1 and heat shrink butt connectors # DW05744-10 to connect the lights...

  • Installing Side Marker Clearance Lights with Two Wires on Trailer
    The Bonded 4 Wire - per foot # 16-4B-1 you asked from would use the brown running light wire for your clearance/marker lights. The LED light you referenced sound like they have two wires so one will be power and the other ground. You can connect them to a battery to test which wire is power as LED lights are polarity sensitive. It is likely the yellow is power and the grey is ground which will be attached to the base frame or metal frame structure on your trailer. Often the clearance/side...

  • What Is Needed To Seal Behind The Trailer Side Marker Light 328-K-51 During Installation?
    I recommend using Clear Silicone # FAS59FR when installing the LED Trailer Clearance or Side Marker Light # 328-K-51. This will allow you to seal the hole for the wiring as well as the holes for the screws. A Caulk Gun # PTW54295 is needed for the tube of silicone.

  • How To Wire a Trailer Clearance and or Marker Light On a Trailer
    I can't speak for all trailer clearance and or marker lights but most like the LED Trailer Clearance or Side Marker Light with Reflex Reflector part # 328-K-51 feature a simple two wire install, one for power and one for ground. If you aren't sure which wire has which function you can test them pretty easily with a battery or reach out to the light manufacturer. The above for example has a white wire for ground and a yellow wire for power. The ground wire will need to be attached to a bare...

  • Weatherproof Sealant Recommendation for Clearance Light Installation on RV
    To add a seal around the mounting hardware on your marker lights, like the LED Red # 328-K-52 and Amber # 328-K-51 lights, I recommend checking out the TremPro 644 Silicone Sealant # 0160297 which is designed for use on a wide variety of surfaces so you can use it for the lights, walls, roof, or really anything else on your RV or around the house. If you don't already have a caulk gun you can pick one up from us with part # PTW54295. Attached are some review videos for you to check out.

  • Recommended Replacement Cab Lights for 2011 Winnebago Adventurer Motorhome
    I might have some options for you to replace the cab lights on your 2011 Winnebago Adventurer but we unfortunately don't know what ones you have currently. I looked up some photos online and they look very similar to the LED Trailer Clearance or Side Marker Light with Reflex Reflector part # 328-K-51 so these might be a good option for you. They measure 4" long x 1-1/2" tall so as long as they match your existing they will be a great fit. I have attached a list of other options below...

  • Option to Replace Glo-Brite Lights
    Hey John, While we do not have any replacement lenses for the Glo-Brite 122R/122Y, we have some lights that can work as replacements. Those lights measure 3.75" long x 1.70"tall, so for something similar I recommend checking out parts # 328-K-51 for amber and # 328-K-52 for red. These are 4" long x 1-1/2" tall and have mounting holes 2-1/2" apart on center.

  • What Type of Trailer Wiring Connector Clamps Down to Connect to Wires
    Sounds like you are describing quick splice connectors like the part # SWC501925-1 which are a pretty standard and easy design most of the time. To make the connection you just set the two wires in the slots and use pliers to close the lid and your set. This part number actually strips the wires too.

  • How Does The Chrome Trim Ring Fit The Command LED Clearance Lights
    The Chrome Trim Ring for Command Electronics Oval LED Clearance or Side Marker Light part # 328-89-386 does just snap over the lens of the LED Trailer Clearance or Side Marker Light with Reflex Reflector part # 328-K-52 or part # 328-K-51. You are correct about the videos, I will put in a suggestion for a video that demonstrates both the light and the ring. The 2-Wire pigtail of the LED lights include power lead and ground wire that will connected to the existing wiring with heat shrink...

    Hello Thomas. It sounds like you are looking for a Command oval amber LED light. I was not able to find any references for the 89.385 part number, but we do have an amber light from Command Electronics part # 328-K-51. This is an oval LED light that measures 4" long x 1-1/2" tall x 1/2" deep so please confirm that this is the size you are looking for. If you need a different size light just let me know the dimensions of your 89.385 light and I am happy to look into it.

  • Troubleshooting Marker Light Not Working on Trailer
    There are only a few things you can check to troubleshoot this. One would be the ground wire. Make sure the ground wire is secure. The other is the power. You can use a circuit tester like the # PTW2993 to check the wire for power. If there is no power then you probably have a short in the wire that needs to be repaired. The other possibility is that the light itself is dead and needs to be replaced. You could use the # 328-K-51 you looked at for a replacement. The light can be spliced...

  • Recommended Replacement Red and Amber Lights for a 1997 Pleasure Way Van
    I took a look at what lights are on your 1997 Pleasure Way Van and I wasn't able to find a direct replacement lens. If you have no idea what lights you have then I'd recommend just swapping the light out entirely with the LED Trailer Clearance or Side Marker Light with Reflex Reflector # 328-K-52 for a red lens and # 328-K-51 for an amber lens.
