I checked a website this afternoon that said the vectra has H7 for the Dip lamp and H4 for the main beam.
I've just checked another site and it says H7 all round.
Which is right?

Sig is indeed correct.
H4 is now only used on older cars and is twin filament dipped/main beam.

Bought 4 x H7 Philips X-tremes for my 05 pre f/l & they all fitted - although with a little difficulty as I had problem getting my hand behind the offside one & then turning the bulb
Mine are all fitted now too. Took the H4s back and got some H7s elsewhere. The hardest one is the offside High beam for sure!
