Mk1 Original Head Light Globes.

[Peter Jones]

right....
but it's just too dim at night

So - just fix your headlights!

Just sticking HIDs into your already stuffed reflectors and dodgy wiring won't help you see any better, will blind other motorists and is illegal.

Replace the reflectors, install headlight relays, buy decent globes. There's nothing at all wrong with 7inch round halogen headlights, they work really well if they're maintained properly.
