Solar bike light

Step 6 Mount to your bike!

I was able to mount this by removing the reflector and just using the same screw and mounting plastic.

Use a screwdriver to tighten and loosen things and position the lamp to your liking. I found that when riding, the circuit turns off the light when under a street lamp.

Have fun, be safe, wear a helmet yada yada...

Could someone show me a way to convert this to a simple blinking LED. This is perfect , but I need one that will blink a red led all night and then turn off in the morning, which this would already do. I really appreciate it.

Get a solar light, find where they soldered the LED(S) remove the ones they installed and put a blinking LED from Radioshack in its place. I hope that helped.

I tried that nak, however there was not enough power to get the LED to blink. If I doubled the battery power it would blink... but one AA battery would't blink the led that I bought at RadioShack.

That's because red radioshack blinking LEDs are approx. 3v. That NiCd battery is approv 1.2v when fully charged. You can use 2 solar panels and 2 batteries but one solar panel and 1 battery is not enough.

This is a great instructional. I do have a question though. Can this set-up get wet? I use my bike all year long, even in snow and rain. I figure the solar panel would be alright, but not so sure on the LED light used. Thanks for a great idea.

Yeah I think that would be fine, as long as you used epoxy over the power connections and other points that could short out in water. I would recommend making a better mount, I lost this one while going over some bumps and had to go find it the next day :/ But yeah, definately worked great before it fell off, I could probably update the instructable with a better mount if I get around to it, so many projects!
