More LEDs
Walking thru Wallyworld, I saw a card display with these funny valve stem caps. Most of them looked pretty doofy, especially the real long skinny ones, and the ones that tried to looked like a helix or a moebius strip. I sorta liked the ones with a rubbery-type-substance-skull-and-crossed-bones-guy. They came two to a card with 6 extra batteries (free), for $5.00. each. They flashed like crazy when you shook them, I figured I'd give them to the grandkids to play with in school (teachers love Grampa Pat, last time it was laser pens. <g>)
When I got home, I discovered that the little-rubbery-type-substance scull-and-crossed bones-guy popped right off. Underneath was a quality valve stem cap topped by a lexan, curved lens over three little leds w/ a tiny circuit board. Not withstanding all of my other lights and reflectors, they look pretty good and bright making white circles in the dark. Even if all of my lights went out, I would still have them and my reflectors which should be enough to get me home. I gave the little guys to the kids, even tho they didn't blink. They proudly put them on the ends of their school pencils (teachers still love Grampa Pat.)
