I'm sure about getting LEDs and I got no idea about the resistors. Can I just buy those "condoms" instead? What's the difference between them?? ← if you want to put leds on, all you need is a multimeter and ohms law (V=IR) the voltages around the console very by a few volts. you should vary the resistor values so that each led runs with the same current and hence have a similar intensity. I've got all my centre console and head unit changed to red leds...the climate control and clock backlights need a bit of tweaking and wide angle leds to get the backlight consistant. The head unit is a different story... if your unsure about leds, then just go with the condoms, however, i do recall some people mentioning some fading...? Another alternative is to simple colour the condomless bulbs the colour you wish, may fade over time tho...
