I run LCDs on most all of my bikes. I have a number of road bikes as will as mountain bikes, they all have lights. When I suggest a headlight was think more in line with the 50's-60's lights that you see with LCDs in them. Most of my riding is done in urban area now and dynamo is not trust worthy you stop riding the light goes out unless you have some thing between it like a capator(I know my spelling is wrong). Trail riding best served by a mt. bike or cyclo-cross bike but hardly ever with a bike with coaster brake IMHO.
I'm beginning to see where all the miscommunication came from.... Check out these videos...
And, of course, Alan Bonds's incredibly informative site:
http://clunkers.net/
(There's a huuuuge pile of klunker info on the internet, with a decent amount right here in the RRB forums...)
A klunker is a balloon-tired cruiser, modified to varying degrees, for use on trails. (There's a lot of secondary terms for'm as well, such as "bomber" and "hybrid"; mostly to do with what kind of brakes you're running, and if you've added derailers or not. Some conjecture exists as to what exactly defines a klunker vs a bomber vs a hybrid....)
The guys from the Transition video are rockin' late-model industrial bikes (but they've since been selling their own production neo-klunker, a model they creatively call "the Klunker", for the past couple of years....

only , designed for mtb use by a company that only sells mtbs and cyclocross bikes...) The other videos show the guys out in Cali who, back in the 70s, went on to pioneer mountainbiking. Before they started fabricating their own frames, they were modifying and trail-riding some old Schwinns, Columbias, etc. It seems like folks on RRB go either route: vintage cruisers OR re-purposed industrial bikes. I've been a confirmed industrial-klunk guy for awhile now, mostly b/c i like that the frames are cheap and easy to replace, but a lot of folks prefer "authentic" klunkers, typically using prewar frames and the "state-of-the-art" era-correct 70s components that the Repack riders used.
Yeah, you can go faster on trails on a mtb or a cx bike, but you can have a lot of fun klunking.... On many less-challenging trails, in my opinion, the klunker is far more fun....
As for the lights, I gave up on batteries ages ago. Too much hassle, juggling batteries, dealing with dim lights as the juice runs out, trying to remember to charge'm. The hub "dynamo" produces wattage on-demand, and the lights I use all have built-in capacitors. The tail light I put on my wife's bike stays lit for a full ten minutes after the bike stops rolling.
this is no quick project as i want it to look right so please give me your input
