I have bought just bought 12k hid's for my 2003 arctic cat zl 550.. We bought the high and low beam bulbs for them with the ballasts..We connected them and once we started the sled they started to flicker, its not an esr so there is no electric start so there is not battery to tap it into. So we connected it to the regular headlights and it produces enough power (12 volts). And yet they flicker, so we called the supplier and they said it needs resitor.. we are worried that if we put them and see that they don't work.. Is this what my sled needs?? Or does it need somthing else like a cancler or a relay.. I would like to know if the supplier we bought it from was right, Please help me on this solution. Thanks!
