Respect The Clave
I've found that this is very handy to have so I don't have to turn on the overhead lights or use a flashlight if on stage. Clips right on the handle, it's small enough to put in your gig bag, and cheap enough to buy a couple for your band mates too. There are probably knock off brands less expensive out there, but I bought mine here:
