brake light

Hi, My hydraulic front brake light switch on my 1973 850 has stopped working. Before I replace it I was thinking about trying to blow it out with compressed air. Has anyone else had any success with this? Thanks , Eric

Any thoughts on a replacement taillamp assembly for a P11? My P11 only has the wiring taped off. No housing, electrical, etc. A lot of people are saying that the new LED kits don't work on old brit bikes because of the positive ground electrical.
