Dome Light Issue

Whats up guys! So I did an LED swap on a few of the lights on my cobalt, but I've run into an issue. My dome light stays dimly lit, even when the car is off. It's quite annoying, it doesn't drain the battery, so it's not that urgent but would a resistor help turn it off (only solution I could think of) or what would you guys recommend? I looked on the interwebs and other vehicles have this issue but no fix, at least not from what I read.

Thanks!

Also, if there's a thread already for this, point me in that direction.

I have the same issue but it doesn't bother me as much any more.

You need to solder in a 1-2 ohm resistor. A regular bulb has that resistance while LED's don't.

I thought you could buy leds with this resistor already in place?

You can't put a 1-to 2 ohm, that would mean 7 to 14 amp draw. 14 Watts of power would get very hot.

I'm going to do mine in a couple of weeks I will come up with a solution and let you guys know.

I had the same issue, I soldered a small resistor across the leads and it draws enough current that the "glow" went away! The resistor I used was small, 47k ohm. One of these:

Strip some of the wire on each side, solder one leg to positive and one to negative and I used heat shrink to cover it all up! Went totally away for me!
