Is it the Bulb or the Ballast?

Whether you have a HID / Xenon  kit or a factory fitted xenons at times the bulbs stop working, there are a few simple steps you can take to determine whether its the ballast or the bulbs.

​

• Check the fuse!

​

• Transfer the bulb from the side that is working to the side that is not working - if the bulb fails to work then the problem this points to the ballast.  Change your ballast or install a bypass kit.

​

• Transfer the ballast from the side where the bulb is working to the side that is not working -  if the bulb on the non working side now works this points to a faulty ballast.
