went to visit artztogo today to sort out a iffy HID light on his Zed, his passenger side HID basically works sometimes and sometimes it doesnt, now to rule out a ballast problem, i swapped the one with the intermittent problem yet met with the same results, on the same side as the intermittent problem . basically his HIDs are fine. would it be a faulty relay or wiring loom issue? as his passenger side headlamp is dead including high beam when the problem occurs

 

Bulbs are fine, as tested them also.

Could be a bad earth, do the high beam lights come on with no lights on, ie flash.

Have you tried a normal bulb to try the circuit?

I wouldnt worry too much about a wiring loom, there are only 2 wires to each lamp, but if you have a duff earth/ground the relay will not switch it, so i would do a continuity test from the lamp to the relay with each wire. HTH

I'm not going to be back with the car till Saturday, so all suggestions are welcome at this stage, I'm leaning more towards a relay issue as its intermittent, rather than continuity. stupid thing is, with a normal bulb in, it displays the same symptom as my N/A did and that turned out to be a bad live? when its working every thing is fine, well part from the full beam that doesnt work on the passenger side, could HIDs blow the relay?

The ballast shouldnt blow the relay, its drawing about the same as a normal bulb, if bad connections or a short in the wiring to the ballast occurs then it could pop a relay or more likely the fuse unless really cooked, but the relays are generally reliable. If i were you Ian, i would start again from the relay to the bulb feed with a tester, to make sure you have no issues, then its ballasts and bulbs, apart from the obvious(fuse) there isnt alot else in the engine bay it can be. Take a couple of relays out of yours to try, but use normal bulbs first. If you dont have an issue at this point you wont blow your relays if its the HID's

Thanks bud, ill let you know how i get on

i had this, turned out to be in intermitent fault on the ballast, would strike fine then it wouldnt
