LUMENS HDRL Relay Harness
Used on vehicles that decreases voltage below 10V or reverses polarity for DRLs. Also can be used on older vehicles to provide better current to the HID conversion kit. This harness is NOT a standard relay harness. Standard relays fail to function properly at voltages under 10V, while the relays used in this harness can be triggered by voltages as low as 3V.
