Load resistor for LED lighting 21W 12V

PRO-LOAD is a load resistor used when converting from traditional 21W lighting to LED lighting to compensate for the power difference in each circuit.

Helps avoid error messages in the lighting system

When mounted in parallel with each circuit, the load resistor converts the power difference into heat and helps simulate a load equivalent to a 21W bulb. It is used during LED conversions when the vehicle — particularly modern vehicles with CAN-bus systems — would otherwise display an error message or warning in the lighting system due to the power difference. Note that this may affect the vehicle's fault indication, meaning that certain faults in the circuit concerned are no longer detected in the same way.
