I REPLACED LOW BEAM BULB, BUT LOW BEAM LIGHT STILL WON'T COME ON. I CHECKED FUSE AND FUSE WAS GOOD.

2003 Mercury Marquis

Low beam head light will not come on. Replaced the bulb, check the fuse, but the lights will not come on.

Check/Test the headlamp switch-start here could be a ground issue too

High/low switch could be bad.
