Got a small problem, but i might know what it is but would lik other peoples opinions, ive got HID's (6k) in my ST at the moment, they both worked well until a few days ago where only one light would come on

Now ive checked everything and all wires are spot on and all plugged in, now the light did come on now and again but not anymore, ive been told it could be my grounded spot either rusty or not grounded tightly.Would this be the case?

Checked it all over. Even tried some different ballasts but nothing. 

Tried moving the headlight to the other side and that didn't work either. So either the HID light itself is knackered or damaged wiring. 

So might just get a new HID kit all together.

Or if anyone has any more comments what it could be?

on my old HID kit the fuse's seemed to have damaged the connectors them selves for the fuse, annoying going over a bump and moving it, so i re-soldered all the connections and improved the fit for the fuse and never had a problem

I mnot sure what it is on here, could be the connector itself, so is it best to buy a connector (just the wires)

Or buy a kit all in all?

if you have plugged the bulb into each ballast and its the same then its just a bulb, if it works sometimes its not getting a proper power it could be connections
