I noticed that I had no brake lights. The fuse was broken. It calls for a 10 amp fuse. I recently connected a third tail light that came installed on the car mounted on the luvures. I put in a 15 amp fuse for the tail lights because with the addition of the third tail light a 10 amp may not be enough. Is my thinking correct or am I making a mistake. What is and how do you figure the amp load of your brake light circit.
