wtf wont my bleeder resistor work? - #3 by Henk4U2.
I would think adding a bleed resistor would allow the leds to get what ever current the bleed resistor would allow. I seen several post talking about the plastic ring around the metal switch being black and wouldn’t let light through. I’m assuming you have a metal switch that’s made to light up with the clear washer and all.
