Hello, my 2001 model 206 Roland Garros vehicle. When I turn on the parking lamps, the light level of the instrument panel, the date-time-thermometer screen and the digital air conditioner screen will be halved instantly, and if I turn on the headlights, it will remain at the same level. When I turn the headlights and parks back to their old level. Is this normal? If it is a problem, what could it be about and how much would it cost? Thank you very much for those who can help. & Nbsp; & nbsp; & nbsp;
