I fitted a HID kit in the end, been on for a few months now....the bulbs are a bit crap though, im wanting to swap them for some better quality HID bulbs if this is something that can be done???

They're H4's, just had a quick look under the bonnet at the power-transformer-thingy's which say on them

"HID 35-MD-03
V in 9-16v
V norm 13.5
l norm 3.2A
l in max 10A
P out 35W norm
T case -40 - +105degrees c"

then it reads to the side "vout 23kv max"

so if anyone knows wether i can swap these bulbs for brighter ones, or any help at all this would be much appreciated as im an electronics retard.

cheers
