I have a 2000 LX.

Yesterday driving home from work at 10 pm I noticed my headlights wouldn't go on. My side markers illuminate as well as the interior lights. I checked the fuses under the hood and they're ok. My high beams work just fine. In fact, I drove home with them on, much to the discomfort of others. I also checked the bulbs. They are silverstars and they too appear to be ok. Could one of the relays be bad? If not that then what? Any help would be great.

Thanks
Dan
