The oem headlights on the vectra are the worst ive ever seen, i didnt really notice how bad they were until i had to travel back from skeggy a few months ago on back roads - it actually got to the stage where i had my front fogs on aswell just to light the road up but hids are brilliant - best move i ever made, can see alot better and hardly have to use high beam (the only difference with high beam is u can see a yellow tinge and a few more feet)
I think the vectra's should all come oem with hids cos the normal lights are lethal
