Assembly Guide
A cool patrol car pot-style emergency light that appears to revolve! Includes control circuit board, LED, switch, and pot-style light dome in clear red. Requires some easy customizing of your car model (drill a hole in the roof, and find a place to hide the circuit board and switch) and the connecting of a few wires. Two LR44 button-style batteries are included, which the boxtop says will last about a week if used 30 minutes a day.
