OK cheers Wayned. Turns out the H1's are blown anyway so I'll get a full set.
Want HIDs but am now wondering if I should just go uprated bulbs route. It's not really my car and although my dad lets me do things to it, I guess it's unfair if they got pulled.
Fitted one of them anyway, passenger. Beam is a little lower them the stock and I think that the Hella has a slightly brighter output. Will tell when dark.
