i upgraded to ap2 headlights/ballasts/ignitor......I changed the bulbs once when i had the ap1 headlights,and the ap1 ballast goes on easy and locks in.I tried to get the ap2 ignitor
to lock into place on the bulb,and it does kinda.but it is a little loose.im pretty sure its suppose to be real snug with no movement.I still have the Ap1 ignitor........i tried it on,and it fit with no problems.Whats the correct postion on the ap2 ignitor.i have it in the same postion as the Ap1.Please help!!!!!!!!!!!!
