Why does The warning buzzer for the lights come on any time the lights are turned on?

Cars & Vehicles

I am assuming you are referring to the head lights. In most cars, the warning buzzer only sounds when all these areoccurring: 1) lights manually turned on, 2) engine is off, 3) door is open. If the buzzer only sounds when these 3 things happen, it's normal.

If this is not the case, there is likely a short or broken connection between the control circuit for the buzzer and one of these sensors. The sensors may be working fine and the connections to other monitoring circuits may be fine which is why it only effects one system. It would be impossible to go into any further detail as to how to locate, diagnose or repair the buzzer control circuit without any vehicles specific information.
