I took these at the World of Wheels today. Didn't get to see the Vette lit, but it also had Vertex's in the tail lights (all 4) and the reverse lights plus a 4LED(?) in the lower windshield.
Then there was this one...
(I resized the pics in photobucket, but it didn't change the size)
Those in the lower area look like Code 3 XT4s and XT6s. From the pics on FB it looks like the rear has a blue LED TA of some type. Not sure what the dash light is you are talking about without a picture. There are several 4 LED lights out there.
