oil pressure light

[DJH]

Hi all

I think I have inadvertently discovered another new way for the ARC to play up and create flashing lights.  When I start up the car, the oil pressure light stays on (the gauge shows pressure). If I turn the car off and start it in the next 30 seconds or so it works normally (no flashing light).

Im pretty sure its not the switch for the light (Ive replaced it twice with new ones and same result).

Anyone got any ideas?

If the gauge is right, take out the ARC bulb...
