One word; MICHAELS....or if you don't have one near you two words; HOBBY LOBBY. Around Christmas and Halloween they have the MOST AWESOME selections of small lights. Look around their "Halloween Village" displays and their "Christmas Village" displays. They have mini Christmas lights, spotlights and others. If you look in the Floral department, you can find tiny floral lights that work wonders. I also use those tiny flexible neck white LED lights with the laser pointers you can find in WalMart by the express checkout. Dollar Stores and Party City have TONS of small clip on LEDs and other small light sources along with colored lights for standard lamps. And of Course, there's Spencers for black lights. I also have a Black and Decker Snake Light I use for some shots. Or you can get a florescent light for use under a car hood. The possibilities are endless!
