There were 6 guys in my wedding party this past October. I went to Sears and they have those yellow 1.5 Million Candle power Spotlights (the kind that recharge and come with a car adapter, etc.)
I was hesitant at first about getting spotlights for them but each one of them has told me seperately that they like their flashlights and they actually use them. I have since ridden with some of them in their vehicles and some of them had them in the car with them, even plugged in at the time. That made me feel like I did ok

The lights are cool because they are compact and have a little zipper storage bag, and they are powerful as hell. There is only 1 out of the 6 guys that even lives in a somewhat rural area.. the rest of them live in major cities but still use them. We had an outdoor wedding in the woods with a reception in an old restored barn, so it kind of fit anyway. I had a tight budget because of how many guys there were, and also they all know I'm still a student so it was cool with them, so these worked out well for me.
I like the sound of those game tickets that were mentioned. That means you get another excuse to hang with the crew, and you are giving them your time and a gift!
