Bike sits in the shed for a month and I always check the lights and tyre pressures before a ride and lately, I find no front brake light. It's the spade connectors at the switch. Seems they corrode and stop the green smoke. I have given then a sand a couple of times but it's still happening. Tomorrow its a full go with a points file and maybe some dialectic grease. Ones a bit loose so it will get a squeeze. Any other tips for a longer fix.
