Re: [EVDL] HID lighting
Actually the HIDs I know take a few seconds to start getting really
bright, and like a min or two IIRC to fully complete the starting cycle.
The starting cycle must be repeated any time the power is cycled, which
is why they're difficult to use as high beams. You can't dim them by
turning them off since it takes forever to get them back on. I'm not
sure if it's healthy for them to be cycled on and off frequently either.
