I ordered a bunch of these red LED blinkie tail lights. They arrived this week. I already had one on my seat post and back of helmet. But this morning I put two on each of the panniers. They were all on the flashing mode. I even though about wearing one on an arm band on my left arm. So that would make five.

And of course, I've got a high-intensity head light up front as well as a helmet mounted one.

Too much?
