Check fuses
Check bulbs
Check grounding wire's then use a test light
Sounds like an electrical problem, check your battery, alternator, and fuse box, and light wiring.
most times it's becauce your tail lights are not working. most auto makers do that to alert you that your tail lights are not woking.
I do not have an answer, but I do have the same problem as you do. I have a 2001 L200, and from the moment you start the engine, every few seconds, the security light will flash and the temperature and gas gauge needles will act as if you turned off the car, and then pop back up where they should be. When the headlights are on, the dash lights will flash along with the security light and the gauges. The headlights and radio are not affected, though. In addition to that, the odometer has also stopped working. It has read the same milage since I noticed some time ago. I will let you know if I find out anything.
I could not be sure about your particular problem, but I had to replace the Multi-Function and Turn signal switches in a 96 Lumina for similar strange problems of Brakes and signals not working in particular scenarios.
check the fuses - there is no fuse for the headlights.
Some cars have a knob for the headlights. If this knob is turned left or right when pulled out, it changes the brightness of the dashboard lights from off to full brightness.
It is probably the running lights that are working and the regular headlights aren't working because of the switch or wiring. TAke it to a garage.
First check your fuses if none are blown then check the switch.
Headlights not working
Dodge Rams are not equipped with Daytime running lights.. Although what you can do is turn on the parking lights and select just your fog lights (if equipped) otherwise to have running lights you will need to turn on your headlights. It's not a huge advantage to have running lights, because when the climates come that you need to turn on the headlights anyways, they aren't necessary.
I own a 2005 jeep Cherokee my headlights on the passenger side is not working changed the bulbs & they are still not working.
Make sure fuse is installed and not loose - same fuse controls parking/tail and dash lights

Had the same problem. Found it to be a bad ground wire for the headlights. There are two ground wires for the headlights, both are directly below the battery. You can see one of them if you remove the drivers side headlight. It is right behind the radiator hose. The other is a few inches from that one.
The headlights and the tail lights may not be working on the 1981 El Camino because of a mechanical breakdown.
