I've tried different bulbs from different places, ranging from £2.50 a bulb to £6.35, but they still keep blowing. I never touch the glass part of the bulb when I fit them.
Strange thing is, it never used to do this when I bought the car new - only started about 2 years ago, and I must have replaced the bulbs 20 times!!! Sometimes they last 2 months, and sometimes 2 days. There must definitely be an issue somewhere, maybe wiring, so I'm thinking of doing the HID conversion. I really hope that will sort it out.
When I asked my Honda dealer what they thought, the guy said it's because I don't buy "genuine Honda bulbs", so I rang a different Honda dealer, and they said it's the normal bulbs you can buy from Halfords. Figures...
