Add oil to engine until level correct on stick.
A low oil level can cause the oil light to blink on a 1995 Honda Prelude. A faulty sensor can also cause this.
top up the oil or change the oil sender unit ???
bad pressure switch
Probably the oil pump is out of service, or the oil level is too low, both are dangerous for the engine integrity.
There is a after market tool you can buy that reset oil that connects to hardness
On the right side of the instrument cluster.
Check your oil level immediately
The light is not an oil light, it is an oil pressure warning light. It is on because you have low oil pressure. Stop driving this vehicle until you find out why the pressure is low. I would start by replacing the oil pressure sending unit as it may be defective. It that does not solve the problem then seek professional help.
This suggests that the oil level indicator or just the light switch is faulty or broken, it can be repaired by any licenced mechanic or perhaps an Auto Electrician
You can reset the oil light in your 1995 Range Rover Discovery by scrolling to the oil life display. Hold the scroll button in until the oil life goes to 100 percent.
If you look in the area of the light, under the speedometer, you'll see a small hole. Put your ignition key in there and turn it to reset the oil change light
change the oil filter
