No headlights

Check the headlight bulbs to see if they're burned out. If so, check that the battery terminals are clean and tight, I've seen both headlights or both brakelights blow at the same time due to voltage spikes because of bad battery terminal connections. If the bulbs test good, then look for a headlight relay to see if that's failed. There should be a fuse and relay chart in the owner's manual, if you still have it.

It very well could be 2 faulty low beam bulbs. Do the high beam lights light up?
