A driver cocooned in the safety cage of an airbag padded metal box with lights ablaze, reduces the perception of hazards for all other drivers distracting their concentration - sometimes with fatal consequences for less conspicuous road users.

Troute Cycle Light  Liberator
This comment from the Bikeradar forum says it all....
"Bought a Liberator 3 from Troute lights.
Run it on full beam flashing 2,000 lumens!
Even had oncoming cars stop on their side of the road.
Best 300quid I ever spent!
Get One and Get Even!
 It's a jungle out there."

Should cyclists have to spend £300 to defend themselves against cars and trucks thus escalating the LIGHTMARE??
