A simple light with a battery and switch

I just wanna a small light with a switch and a battery on my cbg. Anyone have any simple ideas on how to do that electronically?. Maybe like a fender light bulb from an amp or something simple like a Christmas bulb. One light would do....

go to the dollar store and grab a toy with an led in it .. or find an old toy or device with an led ,, either use as is or connect with 2 wires and ad a switch to one line as a breaker .

small thin xmas light will work .. just pull one out , it should have 2 wires or contacts to solder to .

So I have some of these type bulbs in your illustration but no box so I don't know the voltage or what battery to use. Also not sure if different on/off switches have different capabilities but radio shack has a few switches...I'm just trying to go for a single bulb like the one in your drawing.....

some times a 9 volt is too much for them .. depending on the bulb it may get too hot and burn out after a few seconds without a resistor . you can try testing them with a 9 volt and work your way down on battery size if need be .

there are many types of switches .. on/off 2 / 3 / 5 way .,. hi low .. steady .. temp etc ..

you want a single on off and have to decide if you want it to stay on or off after fliping the switch .. or just whils the button/ switch is depressed / flipped .

tell them what you want at at the counter .

i think you want a single on / off toggle .

if you are willing to pay for the switch .. it may be in your best interest to tell them exactly what you want to do .. they can set you up with the whole unit .

taking apart a simple flash light may be an option too .

Thank you very much for the detailed info! I appreciate that very much. I was trying to use one of the calculators to determine what kind of battery goes with 2.5 volt bulb but I don't get how the calculator works.... I'll prob just waist a few bulbs and use some alligator clips....can you solder wires to a battery?

i wouldnt solder to a battery ,, its best to use an existing battery pack from an old toy .. even if you have to take the back off and use the whole back piece them hide it in the guitar . a simple battery holder / pack is cheap at radio shack

ps .... AA and AAA batteries are 1.5volts . 2 or 3 should do the trick.

a 9 volt may be too much in some cases .

I like this basic type of mini light because I have hundreds in case they burn out...so once I find out how to light just one and with an appropriate battery I'll have quite a few spares...

You need to use a resistor with an led in order to get it to glow. There's a bunch of online calculators you can use. Like this one http://led.linear1.org/1led.wiz
