I recently purchased Xentec HID Fog conversion kit online and got in installed by a local workshop. When I left from there I forgot to check if the fogs were working or not and I got home and realized that they are not working. Since they were closed and it was weekend I couldn't contact them until Monday and they asked me to stop by sometime and they will fix it for me. However when I went there the guy turned on the switch for the headlights and fog lights and they came on without doing anything to them. Then when I talked to him about it he said since HIDs are highever voltage then the stock bulbs, the switch has to be turned on in order for them to light up. Is this true?
