Abstract
A magnetically controlled warning lamp has a light module and a circuit board mounted in the body. The circuit board has a magnetic device, a control module and a power module. The power module provides the control module and the light module with a working voltage. The magnetic device is activated to generate a trigger signal by a magnetic field. The control module changes the operation mode for the light module based on the trigger signal. A user can use a magnet to activate the magnetic device to easily change the operation mode for the light module instead of disassembling the warning lamp.
