Oil warning light on when idle but when driving it goes off

Hi looking for some help please!

My girlfriends corsa is a X-reg 1.0 12v envoy
it started leaking oil the other day the filter was clogged up to the max so changed that and the oil n spark plugs. It sounded healthier when we first started it up but after idling for a while it was making weird clanking noises and the oil light came back on, there is defiantly enough oil in it!
When its driving it sounds smoother than before and the light goes off but when u slow down or stop the light comes on again and the idle is still rough.

Any ideas of what up with it would be appreciated, cheers :)

could be the oil pump mate because when u are driving it builds more pressure and when u slow down the pump slows down.

if the oil filter was clogged up its more likely to be the oil pressure switch having a bit of crap in it .for the price of a switch just change it first . also how was it allowed to go so far without a service if the oil filter was clogged up whats the inside ot the engine like ? it really should have had an oil flush while it was being changed ,if a switch wont cure it then im afraid the pump is on the way out and in reality neglect is bloody expensive
