I would like to install brighter backup light bulbs in my 2009 VW Tiguan SE AWD. The bulbs I am considering are Phillips 12789LPB2 Bright White Vision LED Back-up Light (921 /T16) Bulbs. The LED bulbs draw only 2.2 watts. Has anyone ever tried them? Did it trigger a light bulb error? I want to know if the juice is worth the squeeze before spending $34 for the LEDs.
