Welcome to HS.com Sumo...Glad to have you aboard..
 Well what you are looking at when you see that glow is just a Steet glow light stick/rod that has been put up under the dash and the Neon tube it's self isn;t visible if you find a spot up high enough under the dash.
 I have 2 Street glow rods in blue under my dash.  all you se is the glow.  I love it.  I'm goin to hide others under the seats and in the trunk..not to mention underbody kit...
 hope this might help and sorry I don;t have pics of mine to show..I will soon though..
