LEDs for window lifter V70

Hello you !!! I’m looking for WEISSE LEDs for the window lifters and the light switch in the V70. The question is only which are the right ones. LEDs with resistance which are suitable for 12V, I found (or rather scuty) only in red, green and yellow.-White LEDs I could find in 3mm (also in 5mm, but there they are too big,or?) . I assume it should be max 3mm. But with what resistance? Is this a calculation example if the LED 20mA needs current strength and 3.2V voltage? Can someone help me ?
