My 1992 Sc400 Lexus has the Fog Light set up but theres no switch to put them on...How do you rig up a way to turn them on.?.

i dont think there fog lights, there actualy for when you turn. atleast thats what i gathered. i have a 92 sc4 as well and the come on with the blinker.

Yeah i noticed when i use my blinkers each side come on depending on what side you turning....Auto Zone has a kit to run your wires to the foglight deal and actually make them be your fog lights...i did that project last week and it looks pretty cool...
