    Hi y’all , so I just got some replacement LEDs from superbrightled.com and they work when the vehicle is in on position or running but when keys are out and truck is off I get nothing from the new lights. I’ve switched them around and still nothing. Does anyone have this problem or know how I can fix it?

    Doesn't the truck dim the old incandescent / halogen slightly when going from running to off?

    LEDs are sensitive to voltage levels instead of dimming like old type bulbs they just shut off.

    Either way, it seems like a voltage drop is happening once you turn the truck off.

    That’s really odd that the bulbs won’t work only in that situation. LED lights are much more sensitive to voltage. Hence the reason you may see a glow in some LED bulbs when you replace them in a house. This can be due to a scant amount of leaking voltage from a switch loop, lamp, etc.
    As far as dimming goes, usually an LED isn’t dimmable to my knowledge unless specifically designed. That shouldn’t apply to auto bulbs though.
    Usually when they don’t work it’s due to a reversed polarity and you can flip the bulb and make it work. And sometimes the bulbs are just cheap junk. That wouldn’t apply to this situation though.
