I have recently been having to keep changing the headlight bulbs. The other week I noticed that the right bulb had blown. I figured that I would replace both sides to ensure that I got an even level of brightness. I usually buy my bulbs from halford but decided to save a fortune and use eBay. Anyway new bulbs arrived and were fitted. Within 2 weeks the right bulb blew. Today the left bulb blew, so I've had to drive with fog lights on (sorry to anybody coming the other way). Does anyone else find they have to frequently change the same bulbs or is it just me? Is there an obvious problem that I have overlooked? Are cheap bulbs less durable?
