Weird HID problem

**Al115** · Wednesday 28th October 2009, 22:35

Brand new premium HID kit from HIDS4U - works fine on the passenger side, but the driver's side light flashes on when I turn the lights on and then goes out and stays out...

Have swapped the ballasts / lights from side to side, and even tried another kit - problem remains. "Normal headlights" work fine of course.

So it looks like a problem with the car (a 2001 S40 T4)... perhaps wiring? Does anyone have any suggestions?

Cheers.....

I had the same thing on mine the other day Alastair

I wired it all up the one side came on and stayed on, the other came on and went straight back off

I tried all the above things and it turned out a) i had the wires done up wrong when they attach to the exisiting headlight wires and b) the wiring to the ballast was crossed ( both plugs look the same ) i swapped them over and rewired the existing headlight wires the proper way and Kablaaammmm " ££££ing Brilliant HID Lights " they are awesome

Anyway hope you get it sorted out soon buddy.

Incredibly enough they are polarity-sensitive... I was surprised and even went to read the fitting instructions

which didn't say anything about polarity, but when I swapped the wires round... HID goodness
