A device for modifying a traffic light using a combined light / camera bulb connected in place of the traditional red, amber, or green light source, allowing the light to function normally while continuously capturing a video signal showing the area around the traffic light.
By employing a mixed light/camera bulb with voltage and intensity sensors, and a microcontroller to control the light system based on supply voltage variations, the challenges of high latency and failure rates in wireless communication are addressed, ensuring efficient and safe operation of road traffic signaling systems.

AI Technical Summary
Existing road and pedestrian traffic signaling systems face challenges in efficiently switching the light sources of mixed light/camera bulbs due to high latency and failure rates in wireless communication, which are not compatible with the stringent safety standards of road signaling.
The solution involves using a mixed light/camera bulb with a voltage sensor, intensity sensor, and microcontroller to control the light system based on variations in the electrical supply voltage, and modifying the signaling fire switch to include a parallel resistance for stable power supply, ensuring rapid and reliable ignition or extinction of the light source.
This approach allows for the safe and efficient operation of road traffic signaling systems with mixed light/camera bulbs, reducing latency and failure rates while meeting safety standards, thereby enabling cost-effective deployment of intelligent traffic management systems.
