How to: DIY Purple DJ Laser Lights
Photographers use a technique called a "gobo" to modify spotlights to help them create various lighting effects. To create a purple DJ laser light beam using this technique, colored plastic sheeting is placed over the spotlight. Light produced from a spotlight passes through the plastic to make a purple-colored beam. Materials for this project are typically available at hobby stores.
