The nice thing about overkill is that you can't have too much overkill.

You're overcompensating for your denial. Or denying your overcompensation. Err . . . Something.

In that spirit,

The nice thing about denial is that even if you are susceptible to it, you aren't prone to admit it.

Always ride with at least two rear lights! You never know when one will conk out - this happened to me the other day when my PDW Danger Zone suddenly turned into a little feeb light that you couldn't even see.

Speaking of feeb lights, I've seen several cyclists recently using them. They look they probably came from a cereal box, vending machine, or Crappy Tire (you need to be Canadian to understand that one) and produce so little light that you can't see them until well after you have already identified the silhouette in front of you as a human on a bike. It seems to me that any company selling a "light" that isn't a light should be forced to stop it as it gives people a false sense of security.

As I was driving my car home today (haven't commuted much this winter ) after work it was dark and snowing. I saw a commuter with two bright blinkees. One on the rear rack and one in the middle of his back (I think on a back pack but he was a bit far away to see). The second light made him much easier to see. I think part of the reason was that one of them was pretty high up. I personally use two lights. One on my rear rack and one on my helmet. I like having one higher up and others have mentioned, if one goes, I have a spare.

Same thing in my city. Guys riding on the busiest streets in full kit after dark, but with extremely wimpy light on the rear. It makes me want to carry spares in my backpack so when I encounter one of these riders I can offer him a light - Imagine, $2000 road bike, shoes/shorts/jersey/helmet, and a Kmart taillight. Sup with that??!?

I usually use one turbo super flash (which are more than powerful enough to be seen in any condition I'm aware of) on the seat post and my 360 viz gives me a helmet mounted rear...I am extremely visible.

The Turbo SuperFlash is under-rated. It's extremely bright! The only thing I don't care for is the weird flashing pattern, but that's not a deal breaker. Awesome light.

A redundant system is great, so I would think a blinky and a solid light would be good. However, I normally use just a non blink B&M dyno light. Put the blinky on if the weather is nasty.

I consider 1 good light to be >95% (almost completely arbitrary, yes) of the way "there" as far as active rear lighting goes. Anything more has drastically diminishing returns and there is no 100%. I usually run 2 with a 3rd for the helmet on certain routes. Lately, I've just been moving light #2 from my seatpost to my helmet on these routes.

If the chainstay lights are to be angled out a bit to the sides I understand but, if everything is to aimed straight back, you could find a better spot higher up (ie helmet) for a 3rd light, IMO. Make sure that the lights and brackets play will play nicely with the the angle of the chainstays.

I did stuff like this for a while, but it's a PITA when getting prepared for a ride or locking up in public. Juggling 3 taillights plus headlights and helmets, gloves, locks, making sure batteries are charged etc. Not sure of this is an issue for you but that's where it became overkill for me.

Love it! Are you (were you) injured?

The optimal amount of lights on your bike is: N+1
Where N= the maximum amount lights you can fit on your bike.

And as someone else said, lasers too. Add lasers. Because lasers are cool. There need not be further explanation on lasers.

Would it be wrong if I made that my new signature?? Or might that create some kind of tear in the space/time continuum if I quote you in my signature and you quote me in yours?

Plus 1 on the cygolite hot shot. The PBSF has a 1/2 watt light, the cygolite has a 2 watt. Try for 2 or 3 different levels of rear lights. like helmet, back, rack or seat stay. I find some blinking and steady work best. Don't forget side lighting and wheel lights too.
