| It's a bit hard to see during the day, but just wait til it gets dark and you'll quickly spot it. As far as I can remember, in addition to the two LEDs by the rear-view mirror, there's an LED cluster at the back of the door pulls/struts as OJM mentions, as well as one inside the door release on each side.
I leave mine set to blue, but I've noticed that it makes things a bit brighter than other colours (just down to the nature of the hue, i think) - the orange blends in a bit more with the dash lights, but for some reason I find it distracting. |
