Here's the ultimate wake up call for all you drag racing gear heads! As the alarm sounds, the staging (Christmas) tree lights illuminate and flash down in sequence! As the last light turns green, the sound of 8,000 hp top fuel dragsters rocketing down the strip will bring you out of the deepest sleep! Also includes temperature and humidity gauges! Features an instant preview of heart pounding authentic visual and sound effects at the push of a button. If you’re like me, you better stock up on batteries because you're going to wear them out playing! Measures 5 1/4" x 9 1/2" x 5 1/2". Requires three “AA” batteries (included). Enjoy!
