Bongo Fury

hi all,
i have a problem with my dash lights.some will come on,others will not.when you tap the dash,or go over a bump,some will go out and others will vcome on.i`ve changed various bulbs,and some bulb holders,but may have a loose connection.
any ideas?
thanks

I had a simlar problem and it turned out to be a dodgy fuse connection. Try resitting the fuses (Total guess).
