Range Rover Sport L320 (2010) light ticker

Hay, I want to get a range rover, now I have visited one that is so great. Now I’ve tried it and I’ve speeded it up with such a bright ticker. In the stand nothing ticks, even if I give gas in idle one hears nothing. However, if I speed up, I hear it even though the windows are closed. When I open it it will be a bit louder. I have found here a video of a range rover that also ticks so brightly. Can someone tell me if that’s normal or what def video: https://www.youtube.com/watch?v=Q3zfo0bLpLg&t=40s Thank you very much for the help.
