This truck is so cute, and is a perfect "in between size" for those that dont want a huge firetruck kicking around the house, but want more than a matchbox size firetruck.
As others have said, it is strange that the emergency lights are not functioning. Rather just the headlights. In order to activate the sounds, it says to press a button on the roof. But there is no compressible button. On a flat surface, pressing the top of the cab down, compresses it against the front wheel axyl. That is where the activation button is. Internally, somewhere between the cab and wheel assembly. So dont expect to find a button on the top.
There are 2 sounds. A running motor sound, and a siren sound.
My new 4yo is very happy with it.
