What causes your oil light to come on when you stop?

If the oil light flickers on and off while the vehicle is stopped or at an idle, there may be a problem with the oil sensor or the pressure is too low. At the very least, the engine should have 5 PSI when not moving. If the PSI is less than 5, this will trigger the oil light and cause it to flicker off and on.

Why does the oil light come on when I come to a stop?

This sounds like you have a bearing clearance that is excessive enough to cause the oil pressure at low engine rpms (when the oil pump’s output is lowest) to fall below the oil sending unit pressure threshold for when the light turns on. That threshold is often in the 7 psi range. I would try missleman’s suggestion for a new sending unit first.
