All my bikes have 1-2 blinkies.

In terms of rear blinkies, I liked the Vistalite 5-LED taillight very much, but it's a bit weak compared to newer technology. The new BLT Rear Flare DX is as brilliant on-axis and has a wider beam than the popular Cateye TL-LD-1000, but due to a different design, it can be bloted through onto a rack, whereas the Cateye cannot be bolted through (I don't trust a blind screw to resist our potholes).

In the front, I have a generator hub with a headlight on each bike.

I also have a "standard kit" in my pannier, with a Road Morph pump, a 700c and a 20" tube (the latter for my daughter), patches, an extra blinkie and a small LED headlight.

Oh, one of my bikes has one Shraeder rim and all others are Presta. My easy solution is to carry a couple of doughnuts so I can safely use a Presta tube in my Shraeder rim. These doughnuts are vailable at $0,10 at your favourite LBS, but you have to order them...

For highway cycling, the BLT Rear Super Doppler DX is the most powerful on-axis taillight I have found yet. From what I have seen, the same design is also available under two or three other names.
