Hi there. I noticed the dipped beam headlamp bulbs fitted to our Hyundai Coupe Siii 2 litre were getting a bit dim. Internet forums suggested that bulbs dim over time, and as these were original equipment I arranged with a local, trusted, garage to fit new Osram Nightbreaker H7's. These were fitted yesterday. My wife drove the car to work this morning and 4 miles into the journey she flicked the mean beam on on a dark A road and immediately all the headlights - dipped and main beam - went out. She managed to pull over to safe spot and called Green Flag, who arranged to take the car back home on the back of a truck. I thought I had done the right thing by providing good bright headlights, but it seems not? Could it be the new bulbs that are at fault or is it just coincidence?
