Power door locks won't work after headlight install?

Just got done installing and getting my new headlights to work, then to find out my power locks won't work. 98 Mustang. Press the lock or unlock button and all i hear is a click, like and electrical click to engage the locks, but nothing happens. Locks work fine manual and key. Also does not work when setting the alarm or starting the car. Checked the fuses, they look good.

Any ideas?

    Not sure on the Mustang, but many Fords have the lock relays in the engine compartment right under the left headlight, or in that general area. Maybe something was knocked loose.

    After installing a headlight replacement bulb ?

    Or installing a new HID lighting system ?

    There's something missing here....

    Maybe your new lights are taking too much power, or you created a ground somehow, try and switch them back out and see what happens.
