There was a thread here where I expressed some concern about the light output of taillights having been done with NightShade. Well I found a comparison tonight that I thought might be interesting for some here. Its all on a GTO but we can work with that.

First, the demonstration of the light output:

Here is the comparison pics (before and after):

To me there is more light output than I expected to be honest. I expected it to be really subdued more.

At any rate, I thought some might find this useful.
