I've been considering drilling 3x holes in the top tree between the handlebar risers to fit the neutral/oil/highbeam indicator lights, I would obviously avoid the structural gussets on the underside. I don't think it should cause a problem because it is only approx 10mm thick where I would drill.

Does anyone see a problem caused by this?
