Hello, it’s about the following: I drive a Passat 3B ́98, this one has like many others also a dimmer for the cockpit lighting. it’s a PWM dimmer. the Passat has the red light times LED, sometimes a light bulb. I have installed LED strips in red in the driver and passenger footroom pure to ambient lighting. it also shines nice only a bit too bright. now I want these dimming so that it also fits the brightness of the remaining lighting, it should not dazzle. used LED strips: I bought a 10 meter roll of it some time ago, the length is short and always prepared for 12volts. there are extra make-ups available where you can shorten one. 1x unit consists of 3x SMD LED in red + 1x SMD resistance with the marking 301 per foot space were used two units which are connected parallel to 12V. if I turn the original dimmer down so far until the brightness is in order only scarcely 6Volt on the LED strips. but now it’s so dark that the rest of the lighting is not nice harmonizing. in the net I find plenty of calculator, which calculates with the preresistance of an LED at 12Volt but unfortunately I don’t find a calculation for a resistance that brings me my dimming. I hope you can help me to use what resistance in my case ever footroom.
