Blinking headlights. - 8thAccord

pmpete · 03-03-2008, 10:25 PM

Hey I noted this quirk about my EX 4cyl shortly after getting the car. Whenever the AC compressor cycles on the headlights dim momentarily. Now I'm used to seeing this on most cars when idling due to low speed of the alternator. But not when cruising down the road. I took to car to the dealer and they told me it was "normal".
While cruising Edmonds forums I noted several post griping about the same issue.
There may be a really good technical explanation for this like the electrical system not "floating the battery" all the time and only charging it when decelerating, using regenerative power to charge it. This is used on other makers cars and saves a few percent on fuel consumption. I just don't know if this consistent with this type of system.
I just hope I'm not smelling male bovine excrement from dealer.
Has anyone else noted this issue on their 8G.

1st time I heard about this.

Driving for the first time with my 08 4cyl at night today I noticed the lights dimming on and off as well. Its annoying-maybe the alternator too small for car or battery? If Honda tells me that is "normal" -I dont think so. I never owned a car in my 40+years that did that-only if it were an old car ready for the junk yard.

I notice a bit of dimming as well. Gonna try it again tonight and call Honda see what they say.

I've always noticed this on every car I ever drove, my sisters 2003 Lancer, my dads 2002 conversion van, my old 2001 Accord, my moms 2001 Accord, etc. It only lasts not even a second and it never bugged me because...everything still worked, so why bother I thought.
