I wanted to take the cigar lighter socket out to clean it properly and check the bulb. Finally I worked out how to do it :)

Once I'd got it out, I discovered the bulb can be checked with the lighter socket in place :bang:... However the cleaning's much easier when it's out.

If the bulb doesn't light up (with sidelights on), first check the fuse - F11 on my 1998 Cinq Sporting.

I hope the following notes and pictures will help you.
