1981 Buick regal keeps burning out switch headlight
 

Ok i have a 1981 Buick regal keeps burning out headlight switch can any help with the a good fix or bypass

If I recall correctly, those headlight switches had a built in circuit breaker to prevent that from happening. Stock lights ?

A. 2 things you should consider, have someone or yourself check how much amperage those lights are pulling. If the number is too high , you might have to install separate relays to handle their power requirements.
B. Where are you buying the switches ,,quality ???
