Oil light flicker when air condition on.

I have Disco '97 Series I. The oil light flikers when the engine is not accelerating. This happens mostly when the air condition is on. When the air condition is not on the oil light does not flicker.

My oil light has been flickering due to low oil level from a clogged pickup tube in the oil pan.

Yours could be from that, or from a wiring/ground issue.
