I've owned my pickup for around 13 years and as far as I can remember, I've never had to replace the headlight bulbs. I've probably replaced a couple of the rear brake or license plate lights over the years, but that's about it. The vehicle that I owned for over 10 years before that, I seem to remember replacing a headlight bulb at one time or another. I seem to remember having to replace them more often on vehicles back in the 1970s and 1980s though.
