I just finished installing a set of Touratech halogens. I don't have a picture site, so I cannot show them. I am very pleased with the result and the functionality. Plus that they look great on the bike.
TIP: The Touratech instructions advise to pick up the lighting relay drive by cutting into the cable harness which feeds the front headlight. I did not like this idea at all. I picked up the relay drive from the red/green wire which feeds the auxilliary socket next to the ignition key. Very clean, and you have couple of minutes of lighting delay when you switch off the bike. This is handy for getting into the garage when you get home etc. BTW, this wire is very accessible and you don't compromise the integrity of the cable harness.
