Hi All, I recently lost my O/S headlight which of course threw a warning light on the dash. After some investigation I discovered it was not the bulb so ordered a set of new bulbs and ballasts from T8ups (at a great price!). I have replaced bulbs and ballasts (not an easy task) and everything has been fine for about a month. Tonight when switching the lights on the same bulb has started playing up. It comes on for a split second then goes straight off. I have checked the fuses and everything is ok there, I'm assuming the new ballasts and bulbs are fine so I need to know if there are any other weak spots within the lighting circuit that people have had issues with in the past??
