They are 42mm so you'll need to bend the pins in a bit to make it fit, would have got 44mm but there isn't as much choice as to number of LEDs in the module/can bus etc. they are actually a lot brighter than the standard halogen, especially if you get some 501 lights with a good few LEDs in them for the map lights
