HID micro DE's
Just finished fitting my "Wassellised" HID micro DE's. In all honesty not a job I've greatly enjoyed, but after a brief stationary ceremonial switching on I think the results will be worth the effort. The job probably took me the best part of 8 hours, a significant proportion of which was devoted to cursing the guy who designed those bloody side panel fixings (specifically the internal bottom front ones) and weighing up where to stuff the large 2300 V black boxes that I wasn't expecting to find in the cable from the ballasts to the lights.
My thanks to messrs Wassell (for the lights & advice), Yonkyo (for more advice on black box location), Rolf for the idea of where to mount the switch and the author of the website:
http://www.bmwman.biz/ for a guide to fitting aux lights and providing the link to

FWIW here's my set up. I made up an alloy bracket to mount the standard Hella switch (same as the one Wunderbra supply with their spotlight kit apparently) alongside the instrument cluster. The bracket is attached with double sided tape (Duck brand with a cloth weave in it) to the underside of the instrument panel.
I picked up the supply from the dip beam to the switch by scotchlocking inside the headlamp unit and leading the cable out through a hole drilled in the bottom of the bulb cap. Like the website author, I used yellow wire for the dip beam feed and red from the battery via a 10A waterproof fuseholder to the relay. All bits sourced from vehicle wiring products including somw rather smart cable sheathing. They sell sheathing & wire by the metre which is handy.
The ballasts are mounted on an aluminium plate I made up to bolt to the MiGSel bar (top quality piece of kit).
I tried to follow Yonkyo's advice on black box location, mounted axially on the front fairing support Y bracket, but couldn't find a wiring configuration that worked. In the end I settled for taping them together back to back and mounting on a pipe lagging sandwich transversely just behind the light unit. Means I can't use the beam adjustment lever but I've never needed to.
The rest of the HID wiring, plugs etc is cable tied to the back of the MiGSel.
Main cock up was the relay location. I had decided on a location out of the way to the front left of the fuel pump, but after cutting all my cables to length and fixing the relay I discovered the forks rubbed against the wiring on full lock! Cables not long enough to change the route so ended up with the relay well taped up & cushioned with pipe lagging wedged in the gap between the fuel pump cover and the tank. Pretty it isn't - I hope it works!
You need patience to do this kind of installation; re-reading Zen & the Art might have been a good idea before I started.
Anyway. they're on now and they work. All that's left to do is sort out an adjustment that doesn't blind oncoming traffic but ensures I get seen.

. And any more weight over my front wheel will make my wheelieing antics harder to perform
