Default Headlights Flickering!

Issue No 7. Headlight flickers.

This is my new issue for my Sorento. As I observed, headlights ON facing my garage wall flickers every 4-5 seconds. It seems likes voltage drops or spikes coming from nowhere or maybe having defective electrical components.

Case: Headlight flicker
Time Occur: Night
at Temp: 23-40 deg
Usage: Auto Daylight seldom used. (always manually turn on)
Starting Procedure: All light and electronics are OFF except for brakes before engine starts.

Anybody have some inputs will be very much appreciated.

Thanks In Advance!

Happy Holidays!

It's a stock headlights for EX, I4. I think it's halogen.

is it only headlights, or any electrical device? There is some issue with Rondo charging system dropping voltage from time to time (especially when RPM drops).

Increase RPM and see if it is the same. Use high beam s too... simply try to see if it affects all electrical system. If so, talk to service. Could be something with alternator or voltage regulator.

I noticed the same thing happening one night a couple of months ago. Was on a dark highway going 50-60 mph and the headlights would dim every few seconds. Haven't noticed it since, and forgot about it. I'm due for an oil change and will mention it.

I too noticed the flickering; I installed silvania silverstar ultras about two months ago; the fllicker was pronounced last night; only did it will driving. Have not had a chance to investigate further; I thought it might be a defective bulb until I saw this thread.
I hope it is not a serious electrical problem as those can be hard to trace sometimes; hope someone finds the source; I'll continue to look at my vehicle for further clues as to the cause.

Hi Guys,

Futher to my observation, I have not seen malfunctions for couple of days now. The temp is dropping to 21 deg. After I went back home every other night, I drop down the garage door and beam before it. Five minutes of low beam without foglight. 2 mins, with foglights another 2 mins of highbeam but nothings appearingly abnormal. The problem is intermittent and it took time to really figure it out.

Thats for now Guys. Hope to hear from your side..

Just picked up a used 2011 LX yesterday and noticed that exact issue last night. Headlights dimming slightly (while doing 55) every few seconds.Didn't notice it when stopped.
