When it's dark outside and your're under a car with lights over you...it's dark under the car. Bring in the Craftsman drop light and see what you're doing! Maybe then that bolt you thought was a cross member bolt will be instead of the drain plug! I also found out that when you have to reinstall the mower deck on your Craftsman riding mower this light is real handy then, too!
First two light bulbs I tried did not work. I considered it strange that I'd have two duds in a row. Third bulb blew within two minutes. Cage which holds light bulb in place is lousy construction, too. Returned to store.
