What does this mean for you? If in the extremely unlikely even 1 relay fails, both lights will still function as normal and you won't be left in the dark. Designed to supply proper current and voltage to the HID system by using the stock wiring as a trigger for the relay. Plug and play use with all DDM HID kits (as well as most on the market). Use this relay harness to connect HIDs to cars with very small gauge wiring that cannot supply the initial surge current required to light the bulbs reliably. Symptoms indicating the harness is required would be intermittent starting or lights going out after being turned on for several minutes and requiring you to turn the lights off and back on for them to turn back on again Power is drawn through TWO 40A relays to allow both ballasts direct power from th
