I would just get a set of driving lights and mount them on the bumper. Hella is a good brand. You should be able to find a pair for under $250 after shipping. However, you should make the distinction whether you want driving lights or fog lights. Fog lights, when properly aimed, don't emit light more than two or three feet above the ground. They're meant to help illuminate the roadway and markings more so than project light down the street.
Driving lights, however, emit light everywhere like a standard headlight.
They are pretty easy to install and most kits come with the necessary wiring, relay, swithc, mounting bracket, etc.
