In reply to Rog Wilko:
A colleague at work got splatted by a coach that didn't see him. They were both heading into the sun and the coach just drove stragight into him from behind. He wasn't very well as a result and his rather lovely bike was destroyed.
The courts did not agree that the 'sun was in my eyes' was a reasonable defence for running him over and found the driver guilty of something, i don't reacll what.
Didn't help my colleague much, and his new bike has been a complete pain from the outset (high end Pinnacle carbon, and Evans less than helpful.
Anyway, full set of flashing lights front and back for me this morning in bright sunlight.
