probably a short circuit in the steering column. that means a new wiring harness ($150-200 + ) must be done soon, or could cause battery drain, or even start a fire.
You may have a pull on your batt, or a surge.
I had this problem and it was a bad alternator.
If the lights flicker when the vehicle is running, the alternator is on it's way out.
Sounds like you need a new battery.
why do my lights flicker and interior lights flicker
Flickering headlights on a 2005 Silverado may be caused by faulty relays or electrical wiring. The fuses and lights may also be going out.
The adjusting screws for the low beam headlights on a 2004 Mini are on the sides of the headlights. There is a screw on the side for adjusting from one side to the other. There is also a screw on the bottom for adjusting up or down.
Lights flicker on camera due to a mismatch in the frequency of the light source and the camera's frame rate. This issue can be resolved by adjusting the camera's frame rate or using lighting sources with a consistent frequency.
Perhaps you turned on the interior lights when you were adjusting the headlights?
Your lights may flicker because they power is really low. It is very common for them to flicker when there is a storm out.
there are 4 switches that are similar for headlights, fog lights, rear defrost and hazard. the headlights and fog lights are on the left side of the steering wheel. rear window defrost and hazards are on the right side of steering wheel.
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.
