Load Resistor AUT-RES-6-50W $6.48ea
  Min. Qty. 1  
Inline Wiring Schematic
Load Resistor Statement:
If installing LED bulbs in your car or motorcycle causes your blinkers to blink fast or causes other electrical problems you may need to install a Load resistor to correct these problems. Since LED bulbs draw much less current then standard incandescent bulbs your electrical computer system may think that your bulbs are not working. The AUT-RES-6-50 should resolve these problems. This is a 6 Ohms 50 Watt resistor that needs to be installed in-line with your tail/blinker lights, one Load resistor (AUT-RES-6-50) is required for each tail/blinker light.

Caution, this Load resistor (AUT-RES-6-50) gets extremely hot and needs to be installed correctly. The flat surface of the AUT-RES-6-50 needs to make a good secure contact on a clean flat metal surface on your car or motorcycle. This will act as a heat sink which should keep the Load resistor (AUT-RES-6-50) cooler. Keep this Load resistor (AUT-RES-6-50) away from oil, making contact with skin, plastic, wires and combustible gases and material. LEDtronics is Not responsible for damage caused to persons or property with installation of the Load resistor (AUT-RES-6-50).

Special Notes
1) For best results, LED lamp output color should be same as Lens/ Filter color above the lamp. 
2) LED Lamps shown are for most standard applications.
3) Some applications may require custom or modified configuration of the LED Lamp.
4) LED Lamps shown are for direct DC or AC voltage supply. External resistor, relays or special circuits may require special LED Lamps.
