Stop The Traffic! - 4-way traffic signal
- Automatic switching
- Adjustable delay
Impress your friends by building a really neat simulated 4-way traffic signal light! Bright red, green, and yellow LEDs are positioned just like a 4-way signal, and automatically sequence. Adjustable timing allows you to change the delay, something we all wish we could do on the road! Runs on a standard 9V battery (not included) and draws only 15mA for long life. Perfect for model railroads, models, and just plain hobbyists that want to build something really neat! Board measures 2.0" x 1.4" x 4.5". From Velleman.
