Re: Replacing H7 bulb
There was athread recently on 147 headlamps, you don't say but presumably youre talking headlamps.
The H7 principle seems to be like the H4 with a wire spring clip bearing on the back of the bulb and 'latched' under claws on the body. Strongly recommend getting a mirror-on-a-stick from local toolshop/diy-store w.h.y. Getting the bulb in without touching the glass and without dropping it is the trick in the space on the 147. Thereafter making sure the cover is back in place and on it's seal is just as amusing and just as important! The clips on ours seem darnes difficult to keep in place.
Doesn't say that in the manual
