$10 Tactical weapon light

          This Instructable will cover how to modify an inexpensive flashlight with a pressure switch and mount to a weapon.  You will have to already have a mounting point on the weapon like a weaver or Picatinny rail.  It's cheap enough you can even give your Airsoft or paintball gun a little tactical bling.

Step 1 Tools and supplies

You will need the following
Supplies

Flashlight (see note)
Wire
Male spade electrical connector
Heat shrink tubing (1/4 and 1/2 inches)
Double-stick mounting tape (the kind with the foam core)
1 inch Scope rings (make sure they will fit whatever base you will be using)

Tools

Soldering iron & solder
Crimper
Knife or razor
Hole Punch (not pictured)

Note: I'm using a Miraclebeam 9 LED flashlight.  It's about $3 at Fry's Electronics or Harbor Freight.  It's cheap, bright and perfect for this specific modification.  If you want to use another flashlight just make sure it's 1 inch in diameter, but you're on your own as far as modifying the switch.
