I'd guess you need to replace the headlight switch. The switch for a 94 isn't too expensive but it IS a dealer only item. The center of the instrument panel comes off with the 4 screws in the corners. Pull the instrument panel, disconnect the plug to the switch then remove the switch from the panel. Recognize that the switch assembly has 3 parts, Headlight switch to turn the headlights ON, clearance light switch that turns on the clearance lights and dash lights and dash light dimmer assembly. It all comes as a package and I think GM had a problem with a few off their trucks for the years that used that switch assembly, so the switch is quite cheap.
30 minutes after sunset
Headlights are required to be turned on in Tennessee 30 minutes after sunset to 30 minutes before sunrise, when visibility it low, and in adverse weather conditions.

Brake light on and why
Legally (at least in Missouri) headlights are required 30 minutes before sundown until 30 minutes aftersunrise.
If a Ford Explorer headlights blink on and off after 10 minutes of driving, it is highly probable that there is a short bad overdrive pump. Rest the car and clean the grounds. Also check for loose or broken wires.
Most states require you to turn on your headlights a half an hour (30 minutes) BEFORE sunset. (That is based on my experience, driving mostly in the Northeast.)
It is recommended to turn your headlights on 30 minutes after sunset and keep them on until 30 minutes before sunrise for optimal visibility and safety when driving in low-light conditions. This ensures that you can see the road clearly and other drivers can see your vehicle.
I had this problem with my 1994 Buick LeSabre and it no longer happened when I installed a new battery. It's been at least 6 months now with no recurrence of the problem. Before the new battery, I noticed that if I waited about 5 minutes after turning off the car, I could get the lights to turn off. Seemed like something had to cool down.
Where I live it is 30 minutes before sunset and 30 minutes before sunrise that you are supposed to have your headlights turned on.
