I needed a bulb with a BA15D base, these had a BAY15D base with offset pins. Like an 1157 bulb. I could not use these in my motorhome.

I reached out to the manufacturer and confirmed that we needed to update the description of the base of the light bulb. We do have the light bulb that has the BA15D base. It is part # DI95VR

  • LED Bulbs to Replace Incandescent on Bargman Trailer Tail Light 30-92-001
    Sure, you can use an LED instead of an incandescent bulb for the Bargman Trailer Tail Light # 30-92-001.

  • Compatibility of Roadmaster LED Bulb with Blue Ox 8869
    It sounds like you have the Blue Ox Tail Light Wiring Kit # BX8869. You can swap the incandescent bulbs for some 1157-compatible LED's. I reached out to my contact at Roadmaster and the # RM-300066-10 will fit. If you want another option, I recommend the Diamond Vehicle LED light bulb # DI52VR. The bulb is cool white in color.

  • Troubleshooting Lights on Haulmark Passport Enclosed Cargo Trailer
    Your trailer's stop/turn/tail lights are powered by the lighting signal circuits from your tow vehicle while the dome light would be powered by the 7-way's auxiliary +12V circuit. Since both work, but not at the same time, odds are your issue is related to grounding. All powered circuits on the trailer ultimately share the same ground connection (to the vehicle battery) and it is possible that if the main trailer ground has now corroded it may no longer be able to support all circuits at...

  • LED Taillights To Replace Existing 8-1/2 X 4-1/2 Incandescent Taillights
    I have a solution for you, but unfortunately our trailer light manufacturers don't make an LED light that measures 8-1/2 by 4-1/2 inches. The best solution I have for you would be do buy the incandescent lights and swap the bulbs out with an LED bulb. To do this, you would want to use part # 30-92-003 for the left taillight, part # 30-92-001 for the right taillight, and part # DI52VR for the LED bulb to replace the incandescent.

  • Converting Trailer Lights to LED Operation
    You have a couple of options for converting your Pace Arrow trailer lighting from incandescent to brighter high-efficiency LED operation. One is to replace the entire set of lights with new LED-type fixtures, but another is simply to install replacement LED "bulbs" in place of the standard incandescent ones that are now in your Bargman lights. This option can be substantially less costly and also far easier since there is no wiring or other modifications needed; you'll simply pull out...

  • What bulb is needed for the Bargman 30-92-106 tail lights?
    The Tail light bulb type needed for the Bargman Surface Mount Tail Light - 92 Series, # 30-92-106, is a 1157 double filament bulb.
