Product updated on 2019-08-28, SBx Parts - SBX:HID:HDRLS, Daytime running light harness with extended leads. Triggers ballasts at low voltages. Single output only, Use this harness on vehicles with less that 12 volts supplied to the daytime running lights., Most late model Fords supply 9 volts to the DRL (Day-time Running Light module) circuit which will kill ballasts and LED bulbs over time. The lights will work without this harness but the ballast may fail with time as well as reduced life time of LEDs.
