Step 1: Supplies

You Will Need:
CR2020 battery holder
CR2032 3v battery
Bright White LED
Normally Open Push Button Switch

tools that will help:
Soldering iron
solder
hot glue
work station

Step 2: Size Up the Led

First you want to find how you want to position the LED on the battery holder. Once you know that you can cut one of the leads down to make room. The solder the switch to one of the led leads.

Step 3: Solder It Together

This step involved one part positioning one part soldering. you need to make sure that everything fits together and that none of the leads touch, shorting out your battery. Once you do that, solder the leads to the positive and negative spots on the battery holder. trim any excess leads.

Step 4: Hot Glue!

After you solder it, i like to protect the connections with some hot glue.

Step 5: Test It Out

go test it out and give yourself a pat on the back for making your own led light!

    Nice one!
    One thing I noticed is that it says a CR2020 holder and a CR2032 battery, wouldn't that be a CR2032 holder?

    3V lithium batteries never sufficiently light up LED's for me....

    that's odd, most leds run at 3v, are you sure your leds are "standard"?

    I use the LED's that work best on 3.2-3.8 volts and 30 mA. Considering that lithium batteries start out at three volts, it never works out too well. I would much rather use something above three volts with a resistor; I have plenty.
