SOURCE: INOP low beam and high beams
The problem is the headlight switch itself - it's one of the most common failures on these cars. The part, brand-new, is about $158 from ECSTuning.com. Replacing it involves removing the airbag and steering wheel - not difficult but a little nerve-wracking due to the power of the airbag.
If this is something you want to tackle on your own, reply back here and I can give you a step-by-step on doing the work yourself. Or you can go to a shop/dealer and just have them do it. They'll probably charge you at least two hours' labor, even though it's a 40 minute job. Let me know what you would like to do.

I have e-mailed you 2 .pdf files, one is the complete headlamp diagram, and the other is the relay locations. Please advise if you need further assistance.

SOURCE: headlights don't work, low or high beam-
Light switch bad or check all head lightrelays . 2 dim ones and 2 high beam ones. one is bad.
SOURCE: 2002 Impala, headlights work however they blink
This may be the start of a worse problem that the Impala eventually developes. The Body Control Module has a design flaw along with the Passlock anti-theft system. You may get away with just replacing the BCM for now. It needs to be reprogrammed at the dealer and the car will not start if you replace the BCM without reprogramming it. I would also recommend against replacing it with a remanufactured one. Repair cost is going to be around $500 at the dealer.
If the Passlock system is also at fault, add another $500 for a new ignition switch and cylinder. If you haven't experienced random starting problems yet, they are coming soon. When you turn the key, nothing happens. I thought my 2002 Impala may have been immune to these problems that I've heard about constantly, however, at 90,000 miles, it became "possessed". The symptoms started slowly and got worse. Beside the interior lights flashing like strobs in the middle of the night (while the car was not running), the headlights would occasionally click off and on a few times while I was driving at night.
The relay switch you hear clicking is the Battery Rundown Protection relay. I'm suprised your battery hasn't drained to the point where the car will not start in the morning.
SOURCE: low beams don't work - both out at the same time.
