Oil light acting funny

[adamekbukmacher]

I have a 95 sedan, stock f22b2 with 258k. Whenever I'm at a red light my oil light will come on and stay on, and when I push down on the gas the slightest bit it will go away. I just changed my oil the other day so I know it's not low, ad there are no visible oil leaks coming from the car. Any ideas guys?
