Just finished my latest mod and I am pretty happy with the results. The installation of the scanners were a PITA, but they turned out exactly as I hoped. Here is a quick video:
They are the dual RGB LED scanners V2.0 from AAC. I tinted them with matte finish vinyl film to screen the view of the LED's and to diffuse some of the light. It worked for both. I custom made aluminum brackets painted black to recess the scanners behind the grill to hide them from view as well. The colors also matched the JDP halos perfectly (which aren't included in this video), which worked out nicely.
I hadn't seen any similar setup done like this before, so I'm interested in your opinions.
