I checked the fuses and there good i was thinking mybe the light switch is bad the parking lights are working and its the some switch
Headlight Switch
ABCDEFGHIJKLMNOPQRSTUVWXYZ
The headlight switch controls most of the vehicle's lighting systems. Many complaints concerning the lighting systems can be the result of a faulty headlight switch. For example, dim or no instrument panel lights, dim or no headlights, dim or no parking lights, and improperly operating dome lights can all be caused by the headlight switch.

A headlight switch.
You'll need to remove the switch to test it. With the switch removed it can be tested for continuity and the connector plug will serve as a test point for the lighting circuits. First test at the connector.
In this procedure the terminals are identified as follows:
Consult the service manual for terminal identification for the vehicle you are working on. If this is not listed in a separate chart, you should be able to identify the circuits from the wiring diagram.
Testing for battery voltage to the connector. Reprinted with permission of Ford Motor Company.
The chart below indicates the test results that should be obtained when testing the headlight switch for continuity. use an ohmmeter or a self-powered test light to test the switch.
Steering Column-Mounted Switches
On some vehicles it is possible to test the steering column-mounted switch without removing it. The test is conducted at the connector at the base of the column. However, on some vehicles it is necessary to remove the column cover and/or steering wheel to gain access.
Change the bulbs. maybe one was blown for awhile and now the other blew. does the daytime running lights work? does the highbeams work? if the high beams also dont work then its the switch. if the high beams work then its the bulbs

hmmmm sounds like you are on the right track with the ground . with as much current as headlights pull it is possible that the intermittent open you are experiencing has to do with heat coming from an open in the wiring . i believe your best bet would be to locate a wiring diagram for your cars headlight circuit and inspect every wire in that circuit as well as one surrounding for thing like : burn marks , corrosion , places where insulation has worn off or is no longer even there ( :) ) ,and i believe you may find something . also , some cars come with a set of relays specifically for the headlights . these the headlights may be drawing extra current through the relay causing it to switch off (means headlights are bad ) , or the relay itself may have worn out over time (relay (s) may be bad ). i hope this helps you
SOURCE: headlights and dash light dont work
You would have to check and see if you are getting any power out of the light switch. There is a seperate wire for the headlights and the dash lights.
SOURCE: 2001 s10 headlights will not come on all the time
are you sure the bulbs are o.k.? if they dont work on both high and low you have ground wiring problem. ground the black wire at the plug with lights on.

The low beam headlamps have a seperate fuse for each lamp in the central or underdash fuse panel.
The right headlamp is fuse fuse 26 (10amp) and the left is fuse 28 (10 amp). These fuse are hot only when headlamps are on so you need to test them with a test light with headlamps on. If they do not have power to them then concern is either headlamp switch or daytime running lamp relay if your vehicle is equipped with this feature, or a bad multifunction switch.
Power leaves the headlamp switch on the RD/YE wire and goes to multifunction switch. It leaves multifunction switch on the other RD/YE wire The wire will then go thru either a connector c2003 located behind the passenger side air bag behind the dash or to the DRL relay if your vehicle has this feature and leaves there on RD/BK wire to the headlights .
SOURCE: No parking lights, fuse keeps blowing.
There is a ground not connected or a wire open that is causing it to blow

The switch could be shorting out and burning out the bulbs I would check the switch then replace the bulbs.
