How to Use the Roadmaster Brite-Lite Wiring Converter with LED Lights

Question:

Hello, I would like to use the RM-732 on a custom car restoration I am doing. It is a 1972 VW Beetle which previously had a 3-wire setup separate wires for brakes, running lights, and turn signals with standard filament bulbs. I will be replacing them with 2-wire LED tear lights. I know that I can use the RM-732 to go from a 3-wire setup to a 2-wire setup, but how will I wire in the LED relay that I would normally need to for the LED lights? Typically if I was going from a 3-wire filament setup to a 3-wire LED setup, I would simply switch out the old relay for the filament bulbs with an LED relay which would provide the necessary voltage for the LEDs. Should I still do this, then wire in the RM-732 between the relay and the lights, so the voltage has already ped before it gets to the RM-732 unit? Thank you!

I am not quite sure I understand what you mean. A relay does not regulate voltage, that is what a resistor is for. A resistor is more often than not required when using LED lights as the lower current draw can trick the system into thinking there is a short which will then send a pulse to the lights causing hyper flash. If you are in fact referring to the relays then I would not have a wiring diagram for this as each are different and will need to be wired according to the pin out which is usually located on the side of the unit.

With that being said, the Roadmaster Brite-Lite Wiring Converter part # RM-732 is made to be used with LED lights so you should not need to use a resistor. If you do then they can be wired into the output between the light and converter box. If you have further questions about wiring a set of LED lights on your vehicle, I strongly recommend you speak to an automotive electrician as they are going to be your best source of info for a smooth and seamless install.
