I am interested in this upgrade, but not sure they will fit. I already have Hella H4 housings, looks pretty much like the photo you have above. But I don't have much room behind, the battery is right behind the pass side and the airbox is right behind the driver's side, neither of which can be moved. Can you give me the dimension from the back of the reflector to the end of the bulb?
Also, does the rubber "dust boot" (the gray thing sitting on the counter behind the lamp in your photo) that seals the H4 bulb stay removed with the LED bulb installed?
Thanks!
