Northern Ireland firm's lights used in safety trials
Staff from charity Sustrans are testing out bicycle lights that gather data about the cyclist's journey in a bid to improve safety. The ICON lights, developed by technology firm See.Sense in Newtownards, can detect when and where a cyclist swerves or brakes suddenly.
The data can then be shared to help make improvements.
The cycling and walking charity said its staff were using the ICON lights to monitor journeys on bus lanes in Belfast.
Some of the bus lanes have been open to taxis as part of a trial by the Department for Infrastructure which continues until next month.
Sustrans said the move came out of concern for cyclists. Philiip McAleese, chief executive of charity, added: "It's not about cars versus bikes, it's about helping us understand how to use the limited road space most effectively."
