My headlights last night started to cut out in and out in about 10 second intervals last night it use to do this before and the problem was the circut breaker underneath the water bottle but I checked that out and the out going side of the breaker is very hot and has actually started to temper the metal does that mean it's screwed or ?

Yes it is time for a new one.The old circuit breaker contacts get dirty and don't let the current flow through so they get hot and then the bimetallic strip springs open and then cools and shuts and your headlights work and then they don't .So replace it .Cheers Kevman.
