I just bought it and didn't realize the low beam headlights are not working. All fuses check ok. The inboard white bulb is lit on high but has no power to it on low. (I pulled the connector and tested with a volt meter) Am I checking the right place? I see the outboard lights have a high voltage warning on the cover. Are these the HID bulbs that I see posts about? This is all new to me so any help would be appreciated.
