Which car(s) does Halfords spare bulb kit 1 fit besides a Citroen AX?

Just had a look at their website. The 472 headlamp bulb is an H4 halogen type, which was common to many/most cars in the 80's & 90's. Not so widely used since the turn of the century. 380, 382 and 501 bulbs are all still in common use, so you will probably find one of any of these somewhere on your current car. The rest of the bulbs and fuses are still in current use, but a little less popular. They may fit something on your car.

Bulb kits in general are likely to have bulbs you don't need, and be missing bulbs that you do need. My advice is to look round your new car (or in your owners handbook) and see what bulbs you are missing. Buy spares from your local motor factor and re-fill your old Halfords kit to suit you.
