Pulsating headlights 07 civic
Hey guys, the headlights on my 2007 civic have been
pulsating for a while now but tonight it was the worst.
Tested the battery with a multi meter and it read 14. We
disconnected the negative terminal and the car remained
running, which I was told if the car had died that would
mean bad alternator, the weird thing is when we re
connected the negative wire to the battery it temporarily
fixed the pulsating headlights... The more power I drew
(heat, stereo, etc,) the headlights would temporarily dim
then brighten back up. Revving the engine SOMETIMES
stops the pulsating. And like I said they dont always
pulsate. Tonight was very cold and it was the craziest I've
witnessed my headlights do that. Almost as of the var
needs to warm up? But sometimes I pull into my drive and
can see them pulsating after driving home from work. I
have yet to replace the battery or alternator, just looking for
some advice or maybe someone who experienced the
same thing and fixed it themselves?
