I bought a spare bulb kit for the TF yesterday at Halfords. You look up the kit for your car on the website or in the shop using the vehicle reg number or go through the lookups. Kit 18 for my car. However, looking at the excellent guides here on the forum there seems to be a difference in headlight bulbs. Might even be others that are different. Not got that far yet.
The kit gives a dipped headlight bulb as a H1 and the forum guide has it as a H7. The main beam in the kit is a H1 but the guide says a HB3a. Theres even a P21/5W in the kit which I am sure the TF doesn't use. So before I take this expensive kit back and call them all sorts of names, I thought I better confirm my suspicions that they haven't a clue what they are doing.
