Absolutely not normal.
Could be a defective oil sensor, but don't take the chance.
Do not run the engine until you find out the problem and repair it.

Hard to believe Honda has ever made an engine without there being an owners manual online. Oh well… Guess it's too much trouble to look… Since you don't care enough to look, why should anyone else?
