The present invention may include a replaceable vehicle light including a lamp body, a printed circuit board (pcb) supported by the lamp body, and the pcb may include a plurality of individual lights arranged in a radial pattern. A controller chip may be included on the pcb, the controller chip may provide electrical energy to each of the individual lights, thereby enabling selective illumination of each of the individual lights. The controller chip may provide a lighting designation, wherein some of the individual lights are designated as primary lights being illuminated at a first brightness, which may illuminate in a radial pattern. The radial pattern may provide a more visible pattern which may be more distinguishable from other roadway lighting, thereby increasing visibility of the replaceable vehicle light.

Disclosed embodiments provide a lighting apparatus with microwave induction. The microwave induction lamp emits electromagnetic waves through an antenna, such as a planar antenna. When a moving object enters the electromagnetic wave environment, the waveform is reflected and folded back and received by a microwave transceiver via the antenna and serves as a trigger signal. When the antenna receives the feedback waveform, a microcontroller-operated circuit activates a lighting device (e.g., a bank of light emitting diodes (LEDs)) in response to detecting the trigger signal. Disclosed embodiments use the trigger signal to turn the lighting device (lamps) on and off and further include a delay function, via a timer, to keep the lighting device activated for a predetermined period after detecting the trigger signal. In this way, a safe and efficient automatically activated lighting apparatus is provided.
