Re: LED's upper and lower on while driving?
Scott is correct.
Bumper LED's are on all the time. However, they dim when the headlights are on, so they are not as bright.
The ones surrounding the headlight (AKA Ribbon lights or Halo lights) only come on with either the parker lights or normal headlights.
And in case anyone hasn't noticed yet, the ribbon lights (which are only on in parker light mode or headlight mode) turn off when the indicator is in use, but only the side that has the indicator flashing. The opposite side ribbon light will remain on.
This applies to Aus SRT's. I assume the US & ROW models do the same?
