Wandering around Halfords today I was looking to see if they stock much that will be of use when my Yeti is finaly with me. There was not much, but I was shocked at the price of a headlight bulb,a Bosch D1S bulb for a Xenon headlight was £89.99!!! Is this a good or bad price? and how long do they last?The card which you take to the counter (the actual bulb is too expensive to be on display) said guaranteed to last three years but that does not sound long for such a high price. I wonder if the originalbulbs are covered by the vehicle warranty.
