    I put my hids in yesterday 55 Watt bi-xenon in the heads and 55 Watt in the fogs in my 07 F-150 and everything worked great I went to leave last night and I had no headlights at all only fogs Well I found a blown fuse replaced it now no fogs or hi beams the hi beam indicator doesn't even come on. I jumped the hi beam relay and still no hi beams. I put the factory bulbs back in and it does the same thing does anyone know or ever had this issue when you go to hi beam the heads just go off no flash to pass either could it be the MFS burnt up? Any help will be greatly appreciated!!!

    High beam relay clicks when you go to high beam

    If the relay is clicking
    I wouldn't suspect the MFS is bad.

    Using a multimeter, check
    for ground on the black wires
    at the factory headlight connectors.

    Some of those HID systems draw more
    amperage than the factory headlight wiring
    can carry.

    I've got ground on the middle wire. Do you think it fried the Lighting Control Module?

    My bad I read 2002 not 2007 hold on for correct info.

    No power to the low beams dark blue/white and dark green/orange?
    Did you check the left and right head light 10 amp fuses in the
    Central Junction Box?
    According to the diagram there is a 20 amp fuse that feeds the main
    light switch and 15 amp fuse feeds the instrument cluster.

    The LCM should be above the Central Junction Box,
    also called a GEM (Generic Electronic Module).

    If it was a bad ballast it wouldn't work at all they work fine on low beam

    What brand HID are they?

    Does your HID bulbs have 4 wires coming out of them
    two larger wires and two smaller wires?

    Still odd that the standard bulbs
    put back in will not work on high beam either.

    If the MFS is making the high beam relay "click"
    then is has to be the 20 amp power feed fuse before the
    MFS or the 20 amp fuse after the high beam relay.

    Next step would be to run a continuity check on the high beam
    wire (light green/black) from the headlight to the CJB high beam relay.
