Just noticed my side lights under the mirror on my D40 have stopped working, anyone come across this before? Its both sides. Is there a fuse to check, or dirty earth ?
You need to prise the mirror glass carrier out.It is explained in the service manual how to do it. When you get the glass out you can get at the bulb no problem.
I'm pretty sure there is also a thread on this forum about doing it. If not here there is definitely one on the US forum. Try and advanced search for "puddle light" as I think that's what it's referred to in some places.
