Our Solar Powered Low Bridge Warning System uses an infrared detection beam installed in advance of the low bridge at a set height threshold. When an overheight vehicle is detected, the system is triggered and a wireless radio signal is sent immediately to a high-visibility warning sign positioned ahead of the structure.
The sign activates instantly, displaying a TURN BACK NOW message in both Irish and English using high-intensity flashing red LEDs, supported by flashing amber LED beacons to maximise driver awareness. The warning remains active for a pre-set period, giving drivers adequate time to stop safely and turn away from the bridge. This system significantly reduces the likelihood of bridge strikes and helps to minimise traffic disruption caused by such incidents.
Fully solar powered, the system operate independently of the electrical grid, providing an environmentally friendly and energy-efficient solution.
