Are there detailed instructions for this ?

Ours had no directions - when I bought it, my kiddo was studying circuits in school so she knew what to do from class.

What size bulbs are these? I need to order some replacements.

Friend, the length of the bulb is about 2.5cm, and the radius is about 1cm.

What does the buzzer sound like? Is it loud or quiet?

Friend, our buzzer sound is the sound of normal motor rotation, the sound will not be very loud.

What is the bulb holder base size? C9? E12? E10?

Friend, the bulb holder base size is E10.
