Researchers at the University of Oxford found that the human brain can notice symbols faster than it notices generic lights, and with this in mind a group from the school developed Brainy Bike Lights, which feature an LED “cyclists” symbol instead of just a row of bulbs.
In tests the team found that people were able to quickly identify that it was a bicycle and more importantly reacted more quickly to it. Those in the study reacted about 100 milliseconds faster, which for a car traveling at 30 mph could mean the distance of 1.34 meters. That could make a difference for those on the bike!
The lights are reportedly visible from a distance of 20 meters and provide a field of view of almost 180 degrees. The headlight version can run for about 50 hours while flashing, and the tail light can run for 200 hours. That should be plenty of time to get noticed.
