Vauxhall Calibra 2 litre 16 V 1992 - Brake system light / Alternator light - Bob B

My brake light & alternator light started coming on intermitently and very dim and as the days have passed they have become brighter but still intermitent but seems to be more with the brake pedal pressed, it still comes on when just driving. The brakes are working just fine. The brake front pad light has alos come on but the pads are just fine.

Regards

Bob.
