Rear LED light effectiveness.
Driving home last night I overtook a cyclist with what from about 100m
away I thought was a very dim constant rear light. As I overtook him I saw it was a Cateye LD600 on the chasing mode where each LED lights up in turn but there is only one LED on at any time. So from the perspective of a driver this mode would appear to be useless. IE only 1 fifth of the light put out compared to either the constant mode where all LEDs are lit or the flashing mode where all LEDs flash simultaneously. Plus from a distance the chasing mode loses the flashing effect. I use two LD600s on my commuter but don't use the chasing mode anyway. But it made me wonder whether anyone knew of any side by side comparisons of LED lights. Given sites like "Your Tube" and Google Video it would be possible to post video clips of different lights "in action" so to speak, perhaps side by side comparisons. As a side issue the cyclist concerned had a poor rear light, no reflectors and dark clothing. But he was wearing a helmet so everything would be OK right? Iain |

I've made the same point many times i.e. that flashing. flickering or
otherwise intermittent lights are bad news and reduce visibility. This based mainly on my observation from a drivers point of view, and the logical argument that less light = less visibility. The counter argument is that flickering will more likely attract attention, but I am not convinced at all. cheers Jacob |

and the
logical argument that less light = less visibility. Does this extend to more posts = more visibility (I got yours twice :-) |

Usenet is a several-tens-of-million node store and forward network, of which Google is just one (albeit significant) node. Sorry if that's slightly tetchy. I do get irritated with people thinking that the way /they/ access Usenet is the 'only' way, and that what works on their client should work for everyone else. -- (Simon Brooke) http://www.jasmine.org.uk/~simon/ ;; All in all you're just another nick in the ball -- Think Droid |
