Making light setup fit retro look?

I'm going to buy a Surly Long Haul Trucker as soon as QBP stocks them. I'm planning to put some bright lights on it, following the plans at Steven Scharf's site. I'd like to put shellacked tape, a Brooks saddle, some Silver bar-end shifters, and a brass bell on my bike, going for that cool retro look. It seems that retro and these lights and a 12W horn don't mesh well, though, not to mention a switch box and extra cables on the frame. Does anyone have pictures of a retro style bike with gadgets that don't look out of place that I could use for inspiration?

On a side note, I'm no electrician. From what I can tell, AAs aren't powerful enough to run 2 14W lights and a 2W strobe. Lead acid is, but I can't charge it quickly while touring or at the end of my commute. Is there a solution? Alternately, do I really need 2 lights up front? If I had one I could get away with AAs, which are much more convenient for a host of reasons.

AAs will run a Prius if you connect enough of them together.

As for idea on aesthetic after some google this don't look too bad. Altho I'm not quite convince about the overall shape of the rack and lamp.

DanPT, thanks for the pictures. I agree that the rack in the first picture looks strange, and I'd rather not limit my rack choice by including variables other than weight limit and price, but the fender mounts look good. I hadn't thought of it. Has anyone done this? What do you think about the height from the road?

Of course, those bikes use dynamos, whereas I'd have batteries, but I can hide them in a rack bag.

I know little about electricity, but I thought that if you were to connect more than 10 AAs together, you'd be over-volting the bulbs or extending the battery life, depending on how you do it. If not, how do you connect more than 10 batteries properly?

iain, the batteries can be connected both in series and in parallel. 10 of them in series would get you about 12 to 15 volts, depending on the type of battery, and these groups of 10 could then be connected in parallel to obtain the necessary life (and provide the necessary current without overheating the batteries).

You'd need someone more expert than I to engineer it for you. The actual current available (and the heat produced) varies with the internal resistance and discharge characteristics of the particular batteries you're using. But my naive first approximation would have me guessing that I'd get at most an hour out of each 10-battery group (a 2 amp load, approx. 2 amp-hours available at 15 volts).

Not bright enough. Remember, I'm going to use two 12V headlights, and a dynamo light would have one 4V headlight. Anyway, I think I can pull off a retro enough look now.
