Re tail lights: I echo suggestions for the fender-mounted Spanniga Pixeo. Super bright, super cute, super easy.

Re headlights: Meh. The ones that look all classic, like the Lumotec Retro are all halogen AFAIK and not very bright at all. I have one if you want to buy it second hand, but I don't recommend it. The CatEye headlight shown on somervillain's wife's mixte is the best option you got, unless you know someone who's willing to replace halogen innards with LED for you.

But more than anything, I really do suggest you consider the bottle (dynamo) as a fairly inexpensive, reliable solution. You can get them for like $30 now, and a bike shop shouldn't charge all that much to install everything.
