J4CKO said:I think for a lot of people one is enough in their minds, and buying a new bulb is too complicated, never mind carrying a spare or having some at home ready, fitting it would involve raising the bonnet and might cut into some Soap opera and get their hands dirty, still as long as they can add credit to their pay as you go mobile whilst driving which is several thousand times more complicated than fitting a bulb thats alright.
Not that it's a reason to drive around for months with only one working headlight, but the designers of some modern cars don't help.
I had a Renault Scenic that stated in the owner's manual that changing the headlight bulbs was a dealer job. The dealer claimed they had to take half the front bumper off to do it, and charged £40. Add the fact that the nearest dealer may be miles away and unable to fit you in for a week, and changing bulbs is not as simple as you make out.
As it happens, thanks to an online owners' forum, I found a way to DIY at the cost of only an hour's swearing in the rain, and lacerations to my forearm.
