If your Mark 2 or 3.4 or 3.8S Jaguar did not come equipped with factory foglamps and you want to add them, you will need a new switch and a proper escutcheon to show which lamps are on. Of if your escutcheon has simply become tired and faded, here is the answer. Ours are very high quality and fit perfectly.
We also sell foglamps, new and secondhand, for these cars, as well as complete lighting switches.
