I was thinking about lightning on VTEC couple years ago too, but what's the point ?

When VTEC kicks, nobody will manage to even notice the sign, they just can wave goodbye

I connected to side lights.
EDIT: ^^^ good one. Never saw this made, but had this idea maybe 5 years ago, just black background, red letters. Never did that, had not enough time because more important things to do to Prelude

Yellow Dream made true.
