I have 6000k bulbs fitted to my Astra MK4 and have done for the past year or so. At the weekend i fired them up and the drivers side one flashed, as they do, and went out. I switched off and back on and it came on and stayed on. It has done this every day since where i have to switch them on off on for both to work.
Does this point to a ballast on its way out you think? or maybe even the bulb? Wiring seems intact and is free from movement
Any ideas welcome. Thanks
