Hello, I just changed all the leds in my car dashboard and I can't seem to notice that they are a little bit brighter than i would like, even on the lowest brightness settings, the circuit that is responsible with the brightness adjustment uses a Infineon BTS730 which has an integrated pwm controller and a 4-5K trimmer made by Piher Spain, but I've been unable to find the model id or anything about it. There is a serial number written on the side but it is unreadable (3541 maybe). I would like to make the new leds dimmer so I am thinking of replacing the current trimmer with a 10 or 15K one, but I need some help into identifying the type I need.
