Default flickering headlights

I have been noticing this lately when I pull up to the garage. It's not enough to notice when driving, and does not do it with the engine off. Anybody had this happen? Will be taking it in to the dealer soon for some work but though I would see if somebody had ideas since the shop probably won't know how to get into their toolboxes.

The only time I've had that happen in a vehicle was when the alternator was about to go. Check that or the battery cables to make sure there isn't any corrosion. I'm not a mechanic though, so don't take my word for it. lol

Check that all your body grounds are nice and clean an tight, also check your connections to your battery and your alternator. if it persists, have the dealer test your alternator.

This is the OEM lights?

Agree, check your grounds.

Also, your alternator may not be providing enough juice.

Battery may also be a culprit, though it's doubtful because your alternator is the main voltage/amp provider when vehicle is started/running: your battery is merely a supplement or enhancer when needed.

Bulb issues may also be a possibility.

Numerous things could be fault... coild be the multifunction switch as well... also in 1989 up to present day chrysler/dodge thought it would be an awesum idea to put the voltage regulator for signaling the alternator to charge.... in the vehicles ecu/ecm... that may also be an issue....

Yep stock lights, I will get the truck in my garage and check out the alt/batttery. Grounds should be good but will look for them.

Ok i have been searching all threads to find information on my flickering headlights. I have a 2010 and i bought it used with this problem. I took it to the dealer and they replaced my bulb and it seemed fine for a week. I took off the headlights and manipulating the headlight harness was creating the flickering. I have tried everything and i cant seem to fix it. I have taken it to two different shops letting them know about the harness and they have attempted to create a solid connection to the harness but still cant shake it. I than took my headlights off again and removed the white piece in the middle of the connection and i have been able to control it for the last 6 months but i still have to bang my headlight to get it back on from time to time. so i am back to the drawing board. I thought it would be a common problem but cant seem to find anyone with the same issue. My next thought is to cut the wires off and make my own harness but i have been avoiding it. I figured it would be good for you to hear this maybe you could find a solution before i do. btw i have gotten two $90 ticket for this.

Hi burningram, just to let you know that your noticing what I noticed on mine. The sad thing this is normal with our headlight electrical system. The head lights and fog lights run on pulse width modulation, which should be used with led lamps, and not with halogen bulbs, for it is noticeable with halogen bulbs. Pulse width modulation is a digital circuit, it's either on or off, so when there is a draw on the electrical system, you'll see the lights flicker, instead of dimming due to an electrical draw with an analogue circuit (straight from the battery). Yes, there is less draw on the alternator, but annoying light flicker to the driver, if the driver notices. Which it shouldn't be that noticeable.
