indicator light stays on dull

does any one know why my indicator light, lights up dull all the time know this is a simply fix but for the life of me cant remember what it was had the same problem with my tin top and sorted it out but cant remember what it was 

had this on mine, was hazard switch. could open it and check contacts inside, prob worn spring or summat

Had the same thing it was the relay playing up  and fuse was blown.
