havent figured it out, im not sure if its a short circuit.Headlights "Cutting Out"There could be several reasons depending on how old/new your vehicle is.
For example, if your vehicle has a security system that is malfunctioning that could cause the headlights to flash.
On "older" vehicles the most common cause is a short circuit in the headlight wiring system combined with the protective action of the automatically resetting circuit breaker(s) for the headlight circuit.
IF the headlights go out because the fuse "permanently" "blows" while driving at night, it creates a very dangerous situation, for example if you're driving on a dark, moonless night out on the highway in darkness.
To counteract for that many manufacturers put in automatically self-resetting circuit breakers in instead of permanently blowing fuses. With the circuit breakers, upon tripping, almost immediately or within a few seconds, reset, turning the lights back on so you can avoid driving off the road.
IF your car has this system, the cutting out and on of the headlights indicates that there is a short circuit in the headlight wiring system. The "recycling" of the breaker is almost always the result of a short circuit condition in the wiring of the circuit in which the breaker is installed. See additional answer below regarding fuses that blow on replacement, or circuit breakers which repeatedly trip.
Fuses That "Blow" Repeatedly
Fuses [and Circuit Breakers] are safety devices designed and installed in electrical circuits TO PROTECT the conductors [wires] from short circuits and overload conditions which can cause extreme overheating that can result in damage to the insulation and the conductors. And worse the possibility of a FIRE which could destroy the vehicle, house, or other structure in which the circuit is located.
When a fuse [and replacement fuses or Circuit Breakers] "blow," especially if it happens repeatedly, is an indication of an UNSAFE CONDITION in that circuit, usually a short.
The proper "fix" is for a qualified technician, who knows what he/she is doing, to troubleshoot the circuit, find and identify the defect, and make proper repair [s], BEFORE replacing the fuse again [with the properly sized fuse or circuit breaker].
Some ignorant few will suggest installing a larger fuse or breaker to solve the problem, BUT that will only amplify the problem, not solve it. Do not follow "bad" advice and install a larger fuse in a misguided attempt to correct the problem. To install a larger fuse would almost guarantee damage to the wiring and an electrical system fire.
A loose or corroded ground wire can cause your 1995 Jeep headlights to blink on and off. Make sure the ground wire is tight and free of corrosion.
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.
bad headlight switch.
That can happen when there is a bad ground to one of the lights.
This Had happened to me... Try changing the dimmer switch... It cured my problem.
I've heard that if you have an automatic light switch sut-off switch and are having problem with your headlights flashing like a police car, it was caused by the cars computer.
it was a recall on those models go to your Lincoln dealer and have the headlight switch replaced
If it is anything like my '88, it is probably a relay. If you have stock fog lights, try turning them off and see if this helps. On mine, if I turn the fog lights off when the headlights start to blink it fixes the problem...untill i turn the fog lights back on that is. there was a recall to correct this-contact your dealer-they repaired mine for free because of the recall.
There are a couple of different times when you'd turn off your headlights. You'd turn off your headlights when the car is off for example.
Most headlight circuit breakers are located in the headlight switches. Headlights are on a circuit breaker automatic reset so headlights don't go out if there is a problem and will blink on and off to get you off the road safely until you can fix the problem. Look for a short in the wiring between the headlight switch and the headlights themselves.
sounds like a bad day and night sensor or bad wiring
yes it will also cause them to blink off & on and
probably got a short somewhere.
If the lights flicker when the vehicle is running, the alternator is on it's way out.
Loose battery or alterator connections
With a scan tool, or try turning key on, off, on, off, on and counting the blinks of the check engine light. blink, blink, blink, pause, blink would be 31.
Normally the blinking on and off indicates there is a broken switch, broken wire, or a piece of bare wire. First, I would test the switches.
why does my airbag light blink off and on on my 92 mercury gran marquis ls
Usually, the headlights are protected by a self-resetting circuit breaker located in the fuse block. It looks like a big aluminum "fuse". If it is failing or is being overloaded by accessory lights, the headlights will blink on and off. 2/5/09 The headlite switch socket may be burnt due to heat.
Possible headlight switch.
do the headlights come on automatically or manually, if manually turn off
how do i turn off the headlights of my toyota 4 runner 2000 while the car is off?
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.
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.
