Hi all,

I'm new on this forum, even though i'm one of the biggest fans and onwer of Vauxhall/Opel cars. Recently, i got a thorny question, so i deceided to join this community. Well, better later, than never... :)
So the question in my mind sounds like: Does someone know the exact difference between the headlight wiring of a Corsa B and an Astra Mk4? I mean, Corsa has originally a single H4 bulb in the light, so when one switches on the main beam, the dipped one goes out, while Astra Mk4 has two separate bulbs, so the dipped beam never goes out. It's okay with the standard setup, but what if i change my Corsa lights to some angel eye, thus, i have to install two (usually) H7 bulbs into them? After that, everything seems to be fine at the first look, but while switching on the main beam, the dipped one goes immediatelly out...
Does someone know a solution for this issue? Maybe the stalks are different inside, even if they look the same?
Thanks in advance for the help.
