This is very interesting Saab kit called Ambient lightning kit for the Saab 9-3 from 2003-2012. This kit, composed of several LED lights, will allow the cabin of your Saab looks like a Jet plane cockpit.
Kit to improve cabin space is sold via cardyourcar web store, at a cost of € 67,83 incl. VAT. But you will admit, seems pretty expensive, but it can give you an idea of how to achieve the same effect but much cheaper.
This video details the brightness and dimming functions associated with the Genuine Saab Accessory ambient light kit currently fitted in our 2011 9-3 Sport Sedan.
Kit consists of two green LED lights fitted in the front footwells and powered off of an extension harness from the cigarette lighter in the center console.
They are activated by the headlights switch (or automatically if so equipped) and the brightness can be adjusted via the dash rheostat switch or by the Night Panel button.
