This project shows how to make some simple lights using a LED, two button/watch batteries, masking tape and a binder clip. Light Emitting Diodes (LED) are useful because of their low power consumption, durability, and low heat.

The small lights can easily be placed on your jacket or hat.  They will help people see you when you cycle while it is dark outside.

Step 1: The Parts

The common items:
1, A small metal binder clip
2. masking tape (other types of tape would work but I find masking tape easy to use)

Less common items:
1.  LEDs (the yellow and red were my choice)  A package of 20 assorted LEDs at Radioshack goes for about $3.00.  But if you are serious about lowering your cost buy the LEDs online.  There are many online suppliers.  The Electronic Goldmine site (interesting site I plan to use soon) had various packages of LEDs.  You want T1 type and I think 5mm size is good.  I believe the red, amber and green are the cheapest.
2.  Small batteries.  These battery are used for travel clocks and lately they show up in those musical greeting cards.  I bought an off-brand pack of 24 for about $3.00.

So depend on the quantities purchased you should be able to make the lights for less than a $1 each.

Note the positive lead of the LED is slightly longer than the negative lead.  The positive and negative leads must be connected correctly for the LED to light.

<p>any advice? I am struggling to make this... I have all the materials</p>
dunrite675 - thanks - hey now that you created an account you should make something and post it.
