2011 Tucson No Dash Dimmer
 

I have a 2011 Hyundai Tucson. It does not have a dimmer switch for the dash lights and is listed as a option in the manual. The lights are very bright at night and I would like to dim them. Can I just add the dimmer switch? Like this on ebay: https://www.ebay.com/itm/Dimmer-Rheo...-/281598752719
Here is the VIN: KMHJT81BBBU119031
Thanks
