I have:

902.613.623.90 - PET switch rear foglight 72-

901.613.623.0X - last number rubbed off, if part number .02 then PET hazard warning light switch 69 , black rose, rubber suround with green plastic insert with fog symbol in white, big clear plastic area on top of black plastic knob(under rubber suround) and clear plastic rod inside. Probably wrong knob(fog) on a hazard switch?

901.613.503.20 - PET switch for fog headlamp -68 black rose(wrong rose?), black plastic knob with small clear plastic area in the middle. Clear plastic rod inside knob with colored tip.

xxx.xxx.xxx.xx - chrome rose, plastic knob with no clear plasic area in the middle of the knob, but seems there is possible to insert a clear plastic rod into the switch(not into the knob)

All the switches look exactly the same marked w. germany 8082 on the back side. They are one stage pull type with four conectors and hole for the bulb holder in the back. All have the same black plastic knob, one of them with the rubber suround. Can all of them be used for regular fog headlights(128/169/118/TN4)
