Hello, we purchased a Ford Edge in February this year, and finding the stock headlights to be weak, I upgraded the low beams to a set of Candlepower.com H9 65w Narva bulbs. I was very satisfied with their performance. I was forced to lower the aim of the lights due to oncoming drivers "flashing" me. Still, they were great..until last night.
I had driven to work in daylight, so the lights did not switch on. The Edge has the daytime running lights, which is a pulsing voltage applied to the headlight low beams that produces a dimmer beam than the standard low beam. When I came out to the Edge to drive home, I had no headlight low beams. Fog lights work, high beams work, no low beams. A check of the two fuses for the low beams shows them to be good.
So today I set about troubleshooting the lights. I found out both H9 bulbs had blown out. It is not noticeable by visual observation, but using a multimeter found both bulbs had opened. Replaced them with the OEM bulbs I had removed, and I have headlights again.
Anyone else have this happen?
