Hi all, I've just dug out the front fog lamps from my long term storage, ready to clean and refit. They are the early type ones with the chrome plated casing, which is good nick, but the light reflectors are well & truly shot, rusted right through. I bought a later set with black plastic casings second hand from Beaulieu autojumble a couple of years ago, which were a pair from the same vehicle but one was a LR lamp, which has a smooth glass in it, and the other has a 'FT' ? lens glass in it, which has diffuser "ribbing" in the glass.I've swapped over the innards, so I can retain the chrome casings. My car originally had both lamps the same; the FT type, which I find a bit confusing. I seem to remember from somewhere it is correct to use one of each type, so I've fitted the LR one to the offside, to illuminate the road ahead, and the FT one to the nearside to illuminate the kerb. I'm assuming you need one of each type, due to the fact that the normal headlights go off when you switch to "Fog" Is this correct?
