I did some TZ tuning... I've used an LED strip that is blue and purple and UV. Because of the UV radiation, it is not possible to take a good picture of it. I hope this small amount of UV won't do any harm. In real life, this looks really good. I also added some extra lighting behind the title and the Bally logo. The title on the speaker panel is illuminated with a thin EL panel. The inverter is connected via a separate power supply to the mains voltage. Of course all of this wouldn't be possible with the original Speaker Panel and the original Translite. I am using my Backglass with custom sky and two black layers of ink, and my Speaker Panel which allows for illumination of the Title only. The COB LEDs are covered with 1 mm Silver HIPS which is white on the other side. This allows for much better light diffusion. There's a strip attached to the upper playfield glass trim (and hidden from the view) which illuminates the upper playfield only, but with the mirror foil on the sides and the glass above the light gets dispersed all over.
