hi, I bought my bike, XT660Z, with Hid bulbs and ballasts already fitted. Totally unhappy with them. The dip is very bright but dazzles all other road users. Main beam takes too long to reach full power and you ride for 3 seconds in total darkness. I have contacted the company who fitted the units and they say all is normal, don't worry about the 3 seconds delay, just use dip! Am taking the units off and replacing originals with good quality halogen bulbs. Anyone else experienced the same problems.
