Hey all, After a beautiful and lengthy night ride last night (vampire rider!!!) I have been thinking about a headlamp modification. I don't know how the older 640 Adventures are set up, but on the '06 there is a pull switch that activates a "passing" light so you can flash the headlamp (high beam in addition to low beam). As any of you other vampire riders out there know, the stock headlamps are pretty good, but each has its weaknesses. The low beam casts wide and is great for going around twisties and stuff, and the highbeam is like a spot illuminating what is way up the road, which means you have to constantly switch between the two. Well, when you hold the passing light switch in, you get the best of both worlds! Obviously the boys in Austria don't want these lamps on at the same time or they would have allowed it when the regular highbeams were activated. My question is this: What do you think would happen if one were to wire the high beam so that both lamps came on at the same time? Battery drain? Harness meltdown? Spontaneous ignition of the air in front of the headlamp? Has anyone tried it? Just curious before I investigate those fancy expensive bulbs.
