Well, I've been mulling the pros and cons of a Lexan style headlight guard. Basically, I don't like them. So have been on the hunt for wire mesh type stone guards. Plenty out there, just nothing that will fit the tiny Adventure lights. Happened to be at Fry's (Outpost) the other day looking at PC cases. I spotted some 120mm case fans guards. Figured, what the hell. $4 for two. Looks like they might fit.... Turns out the fit like a charm! Cut off the two outer rings and this made the arms where you screw them into the case the perfect length. I kid you not! After a little bending + expanding two mounting holes a bit, they screwed right on to the two head light mounting bolts. One arm I cut off completely and the other I bent in so it rests on the head light case where the adjusting screw is. The metal is a lot stiffer than I though it would be, so it appears just having the two mounting points will work. If not, I can rig a small, low tension spring to the arm I cut off to hold it more securely in place. There is about a 1/4 inch gap between the lens and the guard. All and all, for only $4 and about an hour or so of labor, pretty slick.
