Dual Medium + Low Intensity Obstruction Lighting System | Turkey 🇹🇷

A look at our aviation obstruction lighting system supplied for transmission line towers in Turkey, combining medium- and low-intensity red obstruction lights with a Duty + Standby redundancy configuration.

🔴 1 × Medium Intensity Red Flashing Light at the top of the tower
🔴 2 × Low Intensity Red Steady-Burning Lights at the middle level
☀️ Solar power system installed at the tower base
📡 GPS synchronisation for coordinated flashing
🌙 Photocell control for automatic dusk-to-dawn operation
🔄 Duty + Standby redundancy — if the main light fails, the standby light automatically switches on to maintain obstruction marking
📊 Remote fault monitoring through integrated diagnostics and alarm contact

The integrated light sensor automatically detects when ambient light falls below the preset threshold and activates the lighting system.

The alarm relay is energized during normal operation and releases when an LED or power fault is detected, allowing connection to a remote monitoring system.

A reliable solution for transmission towers and other tall structures requiring continuous aviation obstruction marking.
