The light indicates the oil pressure and not the oil level. Either the oil pressure sensor and/or wiring is damaged or the oil pump is not working properly. I would check the wiring and the sensor first, if all fine then check the pump.

I also have an 81 xv750 Virago, your starter might not be engaging the idler gears that engage the flywheel. This was a huge problem for Yamaha with this bike. A good test would be to first remove the starter from the bike and attach the power leads, hit the start button and see if it turns, if so it is either the idler gears are worn out and it can't "grab" them or the clutch on the starter went. Had this issue last year. The oil light is fine, look on the left side sight glass to see where your oil level is. Idler gears are all special orders so let me know if you can't get them I have a couple spares. The flywheel is no longer available and if it is the starter try to have it rebuilt, replacing it is about $300.00. I had mine rebuilt for about $20.00.

The oil light DOES NOT indicate oil level, but rather oil pressure.
It the light is on all the time, at first I'd say a by-pass valve is stuck open, a oil pump drive key is sheared, oil pump is shot, etc.
Then I read further where the bike fell over, and I'd tend to say it's the oil pressure sending unit.
Remove unit from bike. Get either a multi-meter or a continuity tester, and hook up to the switch (+ to electrical terminal, - grounded to body of switch). Where the switch threads into the engine, it is hollow. Down inside is a spring loaded valve. Using a blunt probe, push on the valve, causing it to move, which SHOULD cause a change in the reading of the gauge. (the switch is NORMALLY CLOSED [N/C], and there SHOULD be a reading at rest, none when you depress valve).

Check the wire at the oil pressure switch.
It mat have come off and is grounding the circuit, keeping the light on.
Change the oil pressure switch.
It may have been damaged when the bike was dropped.

Sounds like it could be a sensor was damaged when it was dropped. Best advice is get someone qualified to look at it.

Could be the oil pressure sensor.

IMHO it's an electrical thing. Guardrailjim called it, see his response.
