How To Make Amazing Lights - Adding LEDs

Want to make a light using LEDs? See how to add LEDs to another device to give it an extra function. This alien looking device in the center picture is not just a cool, red, LED clip light... it actually has a hidden function (its original purpose). That's right, we are fitting LEDs inside other products then adding a battery and a switch so that both functions can work separately.

I have repurposed allot of different things to create new LED lights but this unique project was a request with a specific purpose. A mild glow light, to work as a night light, was requested for use in a car for driving with kids after dark. For this build I chose a calculator with a clear plastic case that also has a clip on the back. This made it perfect for this LED project because once finished it could be clipped anywhere in the car... actually, it could be clipped anywhere for a nice red glow effect. Clipped on a backpack or bike would make for a great light so that cars see you more easily. Or clip it to a belt for late night walks or walking your dog.

The build was quick and pretty easy. I added two bright white LEDs, a 3V button cell battery and a mini switch (the hardest part was figuring out how I wanted the switch and that was really pretty easy). Once everything was put back together it worked better than new. I still had a fully functioning calculator which could independently serve as an accent light (you can even use both at the same time in the dark if needed). Check it out for yourself and let me know what you think.
