Got a rock through one foglight. Never found foglights much use, but didn't wish to run around with a broken one.
As I was planning and fitting them, I intended to take pics and write it up to load on here. Then time pressed and weather deteriorated so I just fitted them. I do feel guilty, so may one day remove one to write the guide as I should have done.
The wiring is fairly simple, one earth, one permanent live direct from battery and a signal from the sidelight. They appear to have some electronics inside that measures battery voltage, so they know when the engine is running. Then when sidelights are illuminated, they dim. I wanted to be able to have them on with side and tail lights, so attached the signal wire to the dipped beam. As the Panda has a single bulb, they dim on dipped beam and go bright again on main beam, Quite comical, but should not be an issue.
Some pics attached. Camera on phone, attached to rubbish photographer!
Gap around lamp sealed with clear building sealant, keeps the muck out from inside the bumper.
