Headlights don't work why?

The new headlights, probably blew the fuse check the fuse and relay if so get a bigger fuse to run the new headlights. Remember when replacing any light in your vehicle to not touch the glass part of the bulb with your bare fingers..

yes ,
check the fuses.

Headlight switch is what it sounds like.

These are all different circuits. The brake lights are on a 10amp fuse - the headlights are on a 50amp fuse - and the parking and dash lights are on a 20amp fuse.
Do you have power going into the headlight switch and the brake light switch ?

Check the headlight Relay and/or fuses - should be in the fuse panel.

First check the fuse, the clearance lights are not factory in most cases and the wiring gets shorted from poor wiring. Once you replace the fuse see if the lights come on, if the fuse blows right away find the wiring to the clearance lights and disconnect them, if the short goes away it is a I said the wiring is shorted. If you don't have the owner's manual you should be able to download it at the link provided. It should be fuse #10 a 20 AMP in the interior fuse box. http://www.fordservicecontent.com/Ford_Content/catalog/owner_guides/97ecoog1e.pdf

Try swapping Relays #45 & #46 in the underhood fuse box. #46 is for the low beams.

Their are adjusting screws in the light housing.look closely & you will find them.Turn headlights on pull up to garage door adust head lights

The DRL's are separate from the actual headlights. It sounds like your headlights aren't working at all. The first thing I would check would be the headlight fuse(s), or relay(s). The location for these should be in your owner's manual.

Hope this helps!
