well i have been having problems with my HID kit which came with the car. So i ordered a new set from HIDS-DIRECT, i was very impressed because i ordered at 3pm on thursday and they came on friday.
I decided to fit them on saturday so i went about taking everything off (bumper,grill, lights) to get access to the front alot easier.
Removed the old HID bulbs and went to fit the new ones but the clips they sent did not hold the bulb in place ,(this kit was specificaly for the MK5 astra) i carried on and used the clips from the old bulbs and fitted the new kit. tested to make sure it works quickly both lights came on.
I then put everything back together bumper, grill lights and turn the lights on and i get the bulb warning on the screen, and it says check bulb :expletive deleted: after all that i just packed everything away and went in as i was pretty annoyed.
Today i took everything apart again to do some testing. I took the ballast off and tried on the other side and same problem the light came on then went off after a few seconds. I got one of my old ballasts (the working one) and tried it on the new bulb and it worked fine. So i have narrowed it down to another dodgy ballast, i can't believe my luck. at the moment i have standard bulbs in which are terrible. Waiting for HIDS-DIRECT to open monday to discuss what they can do.
