[QUOTE 1627766, member: 45"]As I understand it you must have approved lights fixed to your bike, but you can do whatever you like with additional lights on bags, body, head etc.[/quote]
Except for that most effective traffic slower, a flashing blue. I suspect rear facing white lights might get you pulled over too. On the subject of head torches they are certainly handy, I had a car full of laddies try to reverse out of an off-license pull in straight into my track last week. The line of thought went beer, beer, beer, oh, a cyclist, sod him. A quick squirt of Li-Ion powered LED into the drivers face persuaded him of his error and he was still rubbing his eyes and cussing as I passed.
On Tuesday my Magicshine ran out of juice and I encountered Dolly Daydream in her Corsa on a backroad with only a Frog for emergency backup. I was honking uphill, she changing up through the gears and we met at a chicane created by two houses with those old fashioned bollards designed to stop cartwheels from taking the stonework out. In a car I take it at 10mph and hold my breath, she thought 40 was more appropriate. There was only a vestigial pavement perhaps a foot wide and I unclipped and dismounted as she came towards me with all wheels locked up. When she finally stopped she wound the window down and said, 'sorry about that'. 'Me too dearie' I replied. It wouldn't have happened with the Magicshine fending off her advances.
