Yep, get a nice strong rear light, and your choice of a decent road light, or a great visibility light.

I run a 600 candlepower LED light for the front of my folding bike (mostly "to be seen"), and a TL-1000 for the back. I plan on getting a 1w Luxeon Cateye for the front to replace that 600 candlepower unit...the 600 isn't "watertight" like you would think looking at the o-rings that are inside of it (Serfas brand)....it fialed on me in a heavy rain. One strike and it's out when it comes to lighting my bike.
