3057 3457 3157 LED Resistors 5W 100ohm are used for fixing CANBus LED turn signal lights hyper flash/fast blinking/flickering, brake tail lights, or daytime running lights(DRL) bulbs error code or malfunction for vehicles due to the some vehicles are note compatible with CAN-Bus LED bulbs.

Important Notice: 

1. This 3157 LED resistors are only compatible with CAN-Bus LED turn signal lights bulbs, not for non-CANBUS LED bulbs. For non-CANBUS LED bulbs to avoid the signal hyper flash or error code, please choose 50W 6ohm resistors.
2. One side requires one piece 3157 5W 100ohm resistor. (Listing sold by pair)
3. Heat sink will get hot. please make sure metal resistance not contact with plastic or wire to prevent the plastic from melting.
