Dome Light LED swap now always on

So I just swapped an LED bulb into my stock dome light spot. It works great except that unless I turn the switch off, the light is always on, just very dim until I open the doors. Is there always current there?

Always power there, and not much ground is needed to light an LED.

Seen this reported here before recently.

I can confirm this "issue" in my '06.
I installed an LED a few months back. It hasn't drained my battery or anything, and I guess I'm used to it by now. Not a big deal to me =]
But I Am curious to know if there is a remedy; I imagine a resistor of some sort.

I had the same with a led strip in the trunk of a mk3. Tried placing a diode in series so voltage has to be present to turn on the diode/strip but still stayed on. Never pursued it. I'll throw a pot on in series one of these days to see if there's a magic value that may work. I was condiering a relay, but that's not applicable in a dome light.

its gonna always be on slightly unless u add a resistor don't worry about it not enough draw to drain anything. I've had LEDs in my truck for awhile now and they are always on and it hasnt been an issue

This has been a known issue for years. It depends on what bulb brand you buy, I have "expensive" ones and they go completely off.

I see that the latest generation is round, mine are flat with 15 LEDs and a heat sink on the back. I also had their 20 LED bulb before the ones I have now which worked great. I just got the newer version for a color temp swap, plus they were $7, not $18 like the current ones (which really are expensive.) I always waited for promotions when I buy, not like I need fancy bulbs "today".

Now I want to make my own with raw components since I have the know-how now, it's not top priority since nothing is broken, lol.

Interesting. They must have some fancy voodoo magic in them cuz the one I have looks identical and cost about the same.
