One of the upgrades I made while rebuilding the R100GS after the wreck was to install a pair of High Intensity Discharge (HID) driving lamps. I don't do a lot of riding at night, but when I do it's usually out in the boondocks where there's little traffic and lots of deer. More light makes sense in that situation, and with the recent availability of the HID light systems, and their low current draw, it didn't take long to justify the purchase. I shopped around a bit before coming across MicaTech who sold both a pencil beam and a wider driving beam lamp. MicaTech is now under new ownership and no longer carries the lamps, but Farklemasters carries the pencil beam. These work so well I decided to use a pair of them on the R1200GS when it came time to upgrade the lighting on it. After you get over the price of the lamps themselves (about $300 each) the biggest challenge is where to mount the ballasts, and how to mount the lamps. The R100GS is no exception, as there's already a lot going on under the fuel tank, what with dual ignition coils and the factory relays and regulators. As shown above, my solution to the ballast problem was to use the spot formerly occupied by the factory ignition coil, and substitute in its place an aluminum bracket upon which is mounted the two ballasts and a hand full of relays. The bracket picks up three brackets on the main spine of the frame, and uses a short boss to provide a standoff for the lower mounting point (that's the circular feature in the middle of the photo below).
