L.E.D lighting issue

I'm not to educated on the whole bulb lingo and various models. I just got some white leds and installed them in the dome assembly. They look nice but the issue is they dont full go out unless i switch the done to off. If its set on door, their still lit about 15%. I dont know what kind to buy to avoid this. Also, i dont want to add resistors and stuff.

I'm almost positive they all do that unless they have resistors

I had some in my old car that i got from superbrightleds that went off when set to door. So what should i look for resistor but in wording?
The sellers info said on/ off . Not semi off

I asked the same question about 2 weeks ago, it's due to residual current that goes in the electrical circuit. Normal halogen bulbs requires a higher minimum voltage than LED to light up, but LED does light up on very low voltage.

This is all normal, don't worry !!

My LEDs have done this for the last 4 years. You learn to ignore it.

Depending on how much power they require, they will stay lit. Its because there is a very weak voltage there (Dont know why)

I measured 6 V with a multimeter, with no load. With a load present, this voltage will go down very quickly.

I put red and white LED strips in my dome light, red when I open the door, white whenever I push it. Luckily, they never glow dimly. Either on or off.

Ok I noticed that the actual door lights don't light up when they should be off. Also, the rear door lights stay off too, like they'll suppose to. On the Dome lights when I touched both sides of the contacts the bulbs go out like they should. So, there is a lil' current there and I guess I grounded it out. So im hoping all I just need is better bulbs for the dome.

my dome doesn't do this, nor do my doors or rear domes.

They function like normal bulbs. I've had a good amount of bulbs in there as well.

The idea of low voltage going thru isnt valid, a normal bulb light up dimly if there is voltage present. Should anyways....

I got my bulbs from ebay, like a 6 or 9 SMD bulb.

Sorry, did you measure the voltage with a multimeter? No? I didnt say it was being driven at 6 V. I said there was a 6 V build up with no load present. Its not being driven in any significant way, so no it cant provide anywhere close to the current needed for a normal bulb. But LEDs to not need much current, so they might actually be getting something like 2 V across them. This is a common issue if you bothered to research it, and its hit or miss. Just because it doesnt happen to you doesnt mean its happening. It only happens if you have the door switch on. Im not sure why you brought up the rear map lights and the door lights because nobody has said anything about those.

^Why would i bother measuring it if i don't have the problem present. I'm just there saying its not NORMAL, because someone else said its normal for him and just deal with it. I'm just telling him to try different bulbs if it bothers him, and apparently he got them from ebay same as me.

I didn't catch your solution to his problem....

I see you like to be an internet bully. Carry on.

Dont act like an authority on topics you dont have knowledge on. It is normal, very common problem. Yes the solution is using a different bulb with higher impedance. Most people just live with it.
