err....American workmanship ?
somthing is wrong with your car.
If the lights blink fast on either side of the car then this means you either have non-factory bulbs in the car or you need to replace your blinkers because one of your lights is out.
electronic short in computer system or a short in a current of the main circuit
When both of the turn signals (indicators) of a car blink simultaneously, it is usually because the hazard lights are turned on.
Most likely poor wiring.
You will have to check all the door sensors.
It is important to know what the warning lights mean when they light up. The ABS light comes on when there is an issue with the Brake system in a car.
clink! (like when a car goes clink if there is a loose screw or something) blink! (the head lights turn on and off)
change light switch
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 the theft lights blink, then that is just to scare criminals away and you can start it with any method you want to. If you are trying to break in(BAD), are hot-wireing it, or are messing with the onboard computer, then the car has detected you are trying to break into it and will not start.
