Had to give up last night because the battery went flat. Put it on charge over night.
I've moved the existing HIDs to the mainbeam cos the bulbs don't fit the UK spec's dipped. The new HIDs are fitted to the dipped beam.
Here's what I've found:
If the lights are tried with both pairs of HIDs fitted the mains and dipped both come on together.
If the HID dipped are fitted with normal halogen mains everything works fine.
HID dips, HID passenger side mainbeam, halogen driver side mainbeam - works fine.
HID dips, HID driver side mainbeam, halogen passenger side mainbeam - Dips and Mains come on together.
It seems that having HID in the driver side mainbeam is what's causing the problem.
This is doing my head in.
Looks like I'm gonna end up with no mainbeam HIDs after all
