You'll be reaching for an umbrella when these realistic sound and light modules go into action! Each starts with flashes from a high-intensity, super-bright LED to create the lightning, followed by a clap of thunder and falling rain -- modules are also available with a variety of whistles and other sounds. Each comes fully assembled with a voltage regulator, sound chip, timer circuit, control circuitry, terminal strips and LED. The timer can be adjusted for recurring lightning and thunder, or you can add an external trigger (sold separately) to start the storm as desired. Measures just 2 x 3 x 1/2" 5 x 7.6 x 1.2cm.
 
Complete your installation with the TR1 Power Supply (#349-1) and speaker, (#349-4000 recommended), each sold separately.
