Oil pressure warning light

On the way home tonight, Fenchurch's oil pressure warning light started coming on at idle. According to the pressure gauge the hot idle pressure is about 35PSI, and at higher revs it goes up to about 50. The light goes out when the gauge is showing about 40PSI. Faulty pressure switch?

Yes, quite common and extremely unlikely that your pressure gauge is
that far out! If your HOT tickover is around 35 psi that is excellent but
it should be at 60 psi HOT when running at 30mph in top gear with that sort of tickover reading. Your Oil Pressure Relief valve (domed nut
to the rear of the dizzy) may need checking for spring length. The length should be 2 55/64" (72.63mm).

The oil pressure light worked OK again today.
I'll get a new one anyway next time I put an order in with the suppliers.

High pressure warning light switches are much sought after! When the normal low pressure switch operates it's too late!!

Pressure switch replaced and everything is back to normal. It was a little disconcerting when the light kept coming on at random.

If random then certainly no use - but if had taken a shift up to say 40 psi that would be very useful for anyone with a highly modified engine !
