jerzyjim, I was looking at your car model under your name it say you own a 94, must be a type o.
The way I had to change my foglight bulbs for my Sc400 '95
1. Take off the front tire's for easier access to foglight (optional), but makes it easier to gain access to fog light casing. Option 2 turn the wheel (left/right) so the front tire faces away from the front fender. unscrew 3 or 4 of the bolts of the fender splash guard to gain access to the fog light.
2. The fog light will be enclosed, with a circular plastic cap. I believe you turn it
counter clock-wise to open the casing. This will give you access to the bulb
and socket.
3. To separate the fog light wire wiggle and tug at the same time, until it jars loose.
*NOTE* disconnect the wire from the socket before you open the clasp. This
keeps the bulb in place and out of your way.
4. To open the clasp, I believe you push down and it will unfasten.
Hope this helps?
