The green indicator lights on the dash are inop but the actual indicators work, also the rev counter has gone down - all other lights etc are operational, what has happened?
1st check your fuses ! indicator light - check ALL indicators are working ie any little repeaters on wheelarch step or corner of bumper. The rev counter is wired via the alternator & is probably a seperate fault that may need an auto electrician but you could try check for any loose plugs or dangling wires under dash 1st
