5.2 Electrical Wiring
The unit operates on AC85-265V. Connect the wires as follows:
- Red Wire: Connect to the 'R' terminal for the Red light circuit.
- Green Wire: Connect to the 'G' terminal for the Green light circuit.
- Common Wire: This is the public line. Connect it to the neutral/common terminal of your power supply.
Ensure all connections are secure and insulated to prevent short circuits and electrical hazards.

6. Operating Instructions
Once properly installed and wired, the BBMI traffic light operates by applying power to the respective red or green circuit. The light will illuminate when power is supplied to its corresponding terminal (R for red, G for green) and the common line is connected.
- To activate the Red light, apply power to the Red wire and Common.
- To activate the Green light, apply power to the Green wire and Common.
- Both lights can be illuminated simultaneously if power is supplied to both Red and Green wires, though typical traffic control applications use one at a time.

7. Maintenance
- Cleaning: Periodically clean the outer housing and lenses with a soft, damp cloth. Do not use abrasive cleaners or solvents.
- Inspection: Regularly check mounting hardware for tightness and ensure all electrical connections remain secure and free from corrosion.
- Seal Integrity: Inspect the multilayer seal around the lenses to ensure it remains intact, maintaining the IP65 waterproof rating.
