Hi all We in Australia are having a massive problem with our headlight switches getting old brittle and falling apart 25 years of 104 deg summers is too much for the poor plastic. I have found some really well written posts on how to clean the switches and get them working again but most of ours are beyond that. What i wanted to know is is it possible to buy standard switches from radio shack and wire them up? If so what sort of switches do i need and what wire goes where? Thanks heaps for ya help
