HID scary story.. lol

The startup current required to start HID's is extremely high. That was your problem. In some vehicles the ballast can't get enough or consistant power through the headlight wiring to light. In these circumstances using a relay would help because it draws power directly from the battery.

Usually under the above circumstances only one will fail/not light/go out, etc. Sometimes (<5% of the time) my left bulb won't start. I don't use relays. However once they get lit, HIDs use less power than stock halogens.

that was "why" i was using relay harness .. to draw power directly from battery.. however, i believe my relay harness was faulty and *disconnet* the circuit for some reason..

now i switched back to headlight plug (plug & play).. with added single relay between plug and ballast.. ^^

follow up

today... i spent some time examing the relay harness which i think was the culpit of this problem..

Guess what, i found the ground connector was "bit" loose at the end and it was on/off while the car moves.. i cut and rebased the connetor end ..

and Tada.. no more sympton ..(spin)

i also secured the "relay" on bolt just in case...

Hopely this is the end of the scary story...(eekdance)
