Solar Signals go ten months without battery change

It’s been announced a pair of portable traffic signals has gone ten months without a battery charge.

Mervyn Lambert Plant supplied the solar-powered Nissen LZA 550 signals to Intelligent Traffic Systems Ltd who hired them to TMO Highways. The company says the signals have been on continuous hire and use in Norfolk since 13 February last year and ran on solar power until 5 December 2023 before they needed a battery change.

TMO estimates that has saved 2,017.55kg of carbon, based on the saving of diesel going to this particular site and the savings in electricity charging the batteries. It says there are further savings in the the cost of charging the batteries and sending staff to site on numerous occasions.

In a statement, Mervyn Lambert Plant called this a real ‘game changer’ for portable traffic light installation, saving time, money and improving the solar footprint of TMO’s and all the other companies (including HW Martin & Ferns) currently running Nissen Solar lights. “No other portable traffic light comes even close to the Nissen LZA 550 Solar’s run time – A ‘Greener’ carbon footprint and more efficiency has arrived for those who operate Nissen Solar temporary traffic lights,” it says.

“While Nissen continues to invent, develop and manufacture innovative road safety solutions, Mervyn Lambert Plant and its partners push forward with solutions tailored for the UK traffic industry needs.”

Solar pedestrian lights are also available.
