This week’s question comes from back-to-college student Andrew:
My class schedule this semester has me riding home at night, so I need some safety lights. The lights at the bike store are not only expensive, but unattractive. How can I make them myself?
I can’t imagine a better combination than bikes and LEDs. You could build your bike light from scratch, or you could hack a dollar-store gadget to blink a few LEDs. We have lots of bike light projects here on MAKE to get you started. Be sure to keep an eye on our bicycle archives for the latest bike projects, too!
