Hi All
I've just replaced a headlight bulb for the sixth or seventh time since I bought the car 16 months ago. They seem to go on an alternative side basis, ie nearside this time, offside next time. One blows about every 8 to 12 weeks. It doesn't seem to make any difference whether I run with them on all the time or only switch them on at night. They are standard generic H7 bulbs, nothing fancy 'cos I can't afford to keep replacing them :)
Anyone got any idea what might be causing this to happen, could this be a power-surge or something which causes them to blow, but if so why does it only blow one at a time and not both together.
I tried replacing them as a pair with slightly more expensive ones (£15/pair), keeping the 'old' unblown one as a spare ... it made no difference to the cycle, they continued to blow alternately.
Cheers for any ideas
