Without knowing which light.....

Some lights hang a little just after the engine is started from cold.

Also, really, guessing now, but I would check oil level to ensure enough oil for good oil pressure, and secondly, a battery check to ensure it’s holding it’s charge stil. Perhaps connecting up to a smart charger would be wise overnight.

Otherwise, a plug in diagnostic will be the best bet.
