Your hair dryer has lights going off inside it what is wrong with it?
It sounds like the commutator is sparking. It means that the carbon brushes have worn down or broken and the spring that keeps pressure on the brushes is now rubbing on the commutator. Do not operate the dryer because it will only damage it further. See if the manufacturer has a parts list for the model you have. Look for a part that is called 'brushes'. They are easy to replace. If you find the parts, check the price of them as compared to a new hair dryer. Sometimes replacement parts are more expensive that the original equipment.
