I want to buy some simple lights for my bike, a Calfee Dragonfly Pro 62CM. I don't want anything big and awkward. What do you guys suggest?

What I would do is use your car to go to taco bell, make sure it's really taco bell, this is important. Use your feet to walk to the... gumball machine. Now, using your... hand, take a few quarters out of your pocket, find the one slot of the one that is selling blinking raver rings you can wear for .50cents. Use your hand to insert the... quarters, next, turn the knob on the machine, make sure it is the knob of the one the quarters are in... Then duct tape these all over your bike after turning them on... You may look like the aliens riding a bike from men in black part one...

Try looking at some of the slim LED battery lights. Something like the ones by Cateye. The smallest ones are fine for in town riding but they have more powerful lights for out of town or off road.
Lots of good new LED types coming through at the minute at pretty good prices.
You could look at bottle or front wheel based generators if you don't want to use batteries. These with LED or Halogen lights are pretty bright.

I have a Trek LED light that comes in two convenient sizes. It is very bright but quite slim. The "big" one like mine is about $40 depending on where you go. The other one is a bit cheaper. I'll have to look at the exact light and post a part number for you later.
