Easy led black light flashlight

This is a very quick and easy way to make a black light flashlight if you have the parts in hand.

This project should take you under 5 minutes to complete.

If you're not a member of CSI, don't worry. There are other fun and practical uses for a portable black light. I have used mine to help spot pet stains on carpet and let the kids make fun drawings with highlighters.

Step 1 Materials

• ultra violet led (courtesy of a kids meal movie toy)
• mini mag flash light
• pliers

I see the plausibility in moving it from the toy to the MagLite, it's much more durable. This also shows that you can go to RadioShack, grab a UV LED, then quickly mod your mini-MagLite. There should be a spare bulb in the rear of the handle, where you unscrew to replace batteries, if you can fit the original bulb witht he spare you can quickly switch from UV LED to plain bulb. Love your 'ible!

A resistor would have been better because I doubt that that LED was 3v DC.

Haha..no, sorry I didn't take more pics.  It was a normal Mag light before.  I realize it is a very simple mod, but I still have fun with it from time to time.

They mean that the toy was was a UV light to start with so why bother swapping the LED over to the Maglite?

Mostly just out of boredom...I get your point though, it does seem a little pointless now.  I must have really been looking for something to do that night...haha
