hids, 06 chrysler pt cruiser

hey guys i just bought this hids for my 2006 pt cruiser and i need a realy dont know how to make one can any one tell me how to. the problem is one the car is off and i turn the hids on they light up but when i start the car they shut off dont know what it is was told i need a relay can any one help me please.

first off, what brand of hid's did you buy? does the kit use a harness that plugs into your factory wiring?git yer swerve on!

I had a similiar problem before on my ranger. my lights didn't turn off they just dimmed when the car was on and everything running on it(air compressor, system, etc). the best thing you can do is check if you have alot of things running to the battery and how much amps does it draw away. because with that info you can either A) get an upgraded alternator because everything else is sucking the juice or B) run a second battery. from there you can run the HIDs to a relay by using a 30 amp fuse for the lead wire and using the light wire as a turn on switch for the relay. thats how i got mine to stop dimming or shut off.

also if any one can give me step by step or a index  how to set the hids to the relay that would be helpful thanks
