If several bulbs do not light at the same time, there may be damage to the electrical circuit supplying the bulbs or a blown fuse.
3. To replace a fuse, pull the fuse out of its socket and install a new fuse of the same amperage. If the fuse blows again, find out and fix the cause of the blown fuse.
