I've just changed my head lights from HID , to 90/140w Halogen and then to 55w Narva intense Halogen and put in better driving lights to compensate.
If HID were legal (mine's a daily driver) I would run them they were terrific 35w per globe draw.
The 90/140w globes draw too much current, so battery doesn't get a good charge when on a night drive.
So its back to candle's for the time being until somebody makes an decent approved round headlight.
