Thanks for taking the time to get the link for me but the installation is for a Xenon lamp because the reflector compartment is where my High Beam bulb goes on non Xenon lights. On my lights the Ring Light bulb sits behind a screwed on box cover between the high beam and low beam projector lamp, where you can't get access to it. The only way I can see getting at it is from behind removing the wheel arch covers or removal of the lights from the front. Anyway I'll work it out and post the result. Thanks for the tip on bulb type, I may have been given incorrect advice.
BTW if you're interested in a power upgrade for your 35d, I've been using a DPChip box with great results on my 35d. Australian turned for Oz fuel quality and based in NSW not in the UK with UK quality. My X5 is a SUV that thinks it's a sports car now.

Cheers,
