+1 to that. IMO HIDs are too bright for a vehicle that doesn't have auto levelling. I have HID50 FF50s and Micro DE aux lights which have isolation switches so if I'm getting flashed by other cars I can switch 'em off- not that I've ever been flashed, the DEs have a very sharp cutoff. Phenomenal performance with no aggro.
I borrowed a mates 1150 t'other night which has an HID dip and got flashed loads, and it just shows up how poor main beam is.
BTW, these look interesting:
