Or you could use nightbreaker bulbs, another improvement over standard, and stops all the faffing about and legal gamble with HID.
Sorry stevie are they a straight swap even in a 600?
H1 bulb on left and H4 on rightStraight swap.
I changed just my dip beam light to HID with ballast, passed MOT no probs, lights are excellent
Night breakers unlimited arrived today an duly swapped. Now night ride an report finding. Wish me luck foccer's....
Thanks... I guess?
