Kind of ironic but mine did that for the first time just the other day. After a few seconds of panic, I remembered that others had reported the same non-event. The oil level was in the sight glass but on the low side.
Also, if you read the owner's manual it addresses this specific phenomenon. I'm paraphrasing," Even if the engine has sufficient oil it is normal for the low oil light to momentarily come on during periods of extreme acceleration, deceleration, or riding on an slope."
