I should have added that when you get one of these, you'll see a little hole in it at head end that is maybe 1/32" that is where the water comes out, it doesn't go through the head of the drill. If you see a dull looking little lens in same area also 1/32" or so that is the place light comes out.
If you'll share the place and which you are thinking of purchasing I'll take a look at it and give opinion. My email is above if you want to email me I'll be likely to see the message.
fyi, I'm not in market for one as I have 3, so I will not be bidding against you, ha...
