well when i worked, i drove home in the dark after working back, but most of driving was daylight. now i'm retired i have been driving in the dark a bit more but not that much more. i think PIP once said if you leave headlights turned on & then start car, that can cause it. well i think a few times i forgot to turn off headlights when i parked it and restarted it with them on, but think the charging systems run at higher volt than other cars i've owned.
Dave that would be a world record, did you still have original globes in? should contact new owner see if his lights went out
it's a pain as last time the ist i30 i had, when it blew 1st light it blew second one a week latter.
