Lights incorporated into tools seems somewhat of an emerging fad. Drills, saws, now ratchets. The drill light serves only to drain my battery down. I've not once found it useful. The light on my Dewalt 12" saw serves only to put some shade on my pencil marking and therefore blocking what would otherwise be a great view down the blade onto the board/mark. These types of accessories inhibit me more than assist. I haven't tried a ratchet with a light, but it occurs to me it would probably be about as useful as the others.
