Yes, the flashes of light are from the electric brake or brush arcing. This is normal and has been present on all of our previous mowers, but the previous mowers had a black housing instead of orange and this made it harder to see the flashes of light.
On a related note, other power tools with electric motors (e.g., drills, saws, etc.) may also show visible flashes of light through the vents, particularly when the tool is powered on or off.
