What if my vehicle has separate high/low bulbs?

With a separate high/low beam configuration, meaning there is one bulb PER function either style projector can still be used. A low beam only projector will replace the low beam bulb/function and the OEM high beam stays in tact. With a bi-xenon projector, this will also replace the low beam bulb/function, but the bi-xenon solenoid can be wired into the high beam circuit. This keeps the OEM high beam bulb in tact and allows for the bi-xenon solenoid to be wired into that circuit allowing for a double high beam blast of light.
