You have a weak ground connection.
On a 1999 GEO Tracker, a bad fuse can cause the headlights and dash lights to blink. A bad voltage regulator or alternator can also cause lights to blink and flicker.
somthing is wrong with your car.
Faulty head light switch.
Sounds like a bad switch or relay.
clink! (like when a car goes clink if there is a loose screw or something) blink! (the head lights turn on and off)
The rule of the road is to flash your high beams to remind them to turn their high beams off.
why do the head lights blink like a strobe. Hmmm, maybe it's a old police unit. If lights are blinking like that it is a anti theft device & only will do it siting still. are on all the time just another safety device added to sell a car.
If you mean the headlight switch, pulling it out once turns on the dash lights and turns off the daytime running lights, pulling it again turns on the headlights.
The switch is wearing out on the inside, just order a new one and replace it.
Because they don't blink
No.
