Dispositivo ausilio alla guida antisonno Drive Alert vintage anni 70 con scatola plastica originale

This device was supposed to help keep you awake, by knowing when you tilted you head and then sending an alarm. I have no idea if it works/worked in any way, what you see is what you get, a 50-year-old battery operated noisemaker, untested with no guarantees. The box measures approx. 2-3/4" square and it all appears in good condition.
