Robert - If a driver thinks I am an emergency vehicle that is a good thing because being seen is how you win this game.

I am not in favour of people running strobes at night as they become a problem for oncoming motorists and other cyclists if one is taking a MUP and the folks who run bicycle lights that are brighter than car headlights also tick me off.

Sure... they can see like it's high noon on a summer day but they blind everyone else.

I have some insanely bright off road lighting that I rarely use on the road and if I do I switch them down to their lowest setting... if I come up behind another cyclist I can actually wash out their lights or create a shadow in front of them that makes it impossible for them to see what is ahead.

In an urban environment a 3 watt light is usually sufficient and a bright but non seizure inducing front blinkie really adds to one's ability to be seen.

As far as main rear lighting goes... it's a PB Superflash all the way. I like being seen from a mile away but again... the flash mode is too harsh on the eyes if you are riding with other people.
