Hello, since my interior (Golf 3) will soon be painted white – including the plastic part around the tacho discs – I have considered the following: I create a tacho disc in black, but the numbers are white. The tacho should then be illuminated with black light LEDs. I now have two questions: 1. Is there anything I have forgotten about my thinking, and is something like that allowed at all? 2. I would like to work something into the tacho disc with which I have the following E Achieving perfect results: During the day, the speedometer disc (except for the numbers of course) looks completely black; but if you set the lighting now in the evening, for example, a “Golf III” appears at a place on the speedometer disc, caused by the black light LEDs. I was thinking here of something like fluorescent color. Do you have an idea to realize something like that?
