99 Toyota Camry - Low Beams don't work

How did you check the bulbs?

Incredibly same thing happened to me couple of weeks ago. Both headlights had been working and then both were out one evening. High beams and high beam flasher worked fine, otherwise complete darkness. (parking lamps were lit but didn't help to see anything) Pulled one bulb and it looked fine. I looked very closely against good lighting - no evidence of damage. Pulled the second bulb and the filament was clearly broken. Check the bulbs with an ohm meter before trouble shooting further. My "good" bulb showed infinite resistance. If both filaments show continuity, next place to check would be the headlight relay located in the fuse box under the hood. Fuse cover should be labeled with its location.

I checked both bulbs and they both seemed okay. Ultimately, what was the solution to your problem? Relay or Bulbs?

Once I have the meter, what am I looking for?

Bulbs.

Continuity. If there's a fault in the filament that is too small to see, there will be infinite resistance, so you're looking for a reading that shows some reasonable amount of resistance - not an open circuit.

Don't let your fingers touch the glass, but here's an easy way to check: just run some wires from the battery directly to the bulbs then touch briefly to see if they light up.
