The light and sound module requires three 1.5V micro batteries (not included). The rotating light features two buttons (1 for sound and 1 for light). The switch on the side of the module housing in the battery compartment allows you to toggle between the two different siren sounds. Both the light (2 minutes) and sound (12 seconds) have an auto power-off function. The vehicle is equipped with a tow hitch. There is space for three firefighters in the driver's cabin. Additionally, there is a slot for the radio and the fire extinguisher. The two large side drawers and the compartment under the roof hatch provide ample space for firefighting equipment (such as an axe, broom, etc.). The vehicle's extinguishing arm is very flexible, allowing it to reach even the lowest places (e.g., under the airplane wings). Firefighters can access the roof of the vehicle via the ladder at the rear.
