Interior LED issue

Hi all ,

I'm new to the forum and just got my '05 KJ a few weeks ago, I haven't really done much to in terms of modding it but I installed some LED's in all the interior (front and both rear dome lights and foot lights) yesterday and the dome lights now stay on while driving

If I lock the car with the FOB and wait approx. 5 sec all the interior lights dim then about 15 sec later they all turn off, and when i unlock it again they all turn on, when i turn the car on and drive away they dim but stay on. Is there a way to fix this or should i go back to stock???

I checked the multi control switch to make sure that its ok and its on the setting right under always on, they turn on when the doors open and dim after a few seconds

any help would be appreciated

So far just gotta live with the afterglow.It's the BCM that is the issue since it has a load detecting circuit that turns off the interior lights and LED's do not have enough load to completely turn off.There are no load resistors right now that stay cool enough to be used in our interiors without being a concern for starting a fire,the current load resistors get very hot.

I did the same to my 07 Lib a month ago and they stay dim while driving. It used to annoy me like mad but not so bad after a while.

This is what people do, when their turn signals flash too fast, or have cruise control issues with LED brake lights (Chevy SSR has this issue), and DO NOT want to use load resistors. They wire in a standard bulb socket to the same wires, put the bulb in, tape it up, and hide it behind the tail-lamp, so both the LED and factory lights are working together, but you don't see the factory light at all. The BULBS themselves are the "load resistor" for the circuit. You have to take the old dome bulb out to put the LED in right? So why not just remove the bulb holder from the housing, tape it up with some thermal tape, and hide it. Then wire the LED into the thing as you did, and only THAT is what you see. That way, both the factory bulb is still in the circuit, so the BCM sees the original load.

There are your fixes, without LOAD RESISTORS.
what kind of thermal tape do you recommend? I'll see if its not to much work, as the dim is barely noticeable during the day and i don't drive at night to much, i've also heard of people leaving in the back dome light completely. I mounted the led lights directly into the factory holder tho, so would i need to remount them?

But the afterglow won't damage the truck will it? I know that the LED's use significantly less power than the factory bulb and i don't want to have any electrical issues later on

I've been driving mine with the after glow for over a year now,I don't even notice it anymore but I also have a 7" flipout screen and AUX digital gauge screen that are pretty bright anyways at night.

I was kinda pissed at first about till I dug up the info on the load sensing ground circuit in the BCM and didn't care anymore since no safe way to bypass it.

ok thanks for the info, i'll keep an eye on this thread incase anything new comes out, I don't mind the afterglow, but i would prefer that the lights turned completely off

Anyone tried CANBUS LEDs?

Howdy!

Just found this site in search because I have the same issue. I was wondering if anyone had tried the CANBUS LEDs with the built in resistor.

http://www.amazon.com/CanBus-Bulbs-W.../dp/B00697MAMY

It was mentioned earlier that current resistors give off too much heat and can be a fire issue. Does that include these types?

I don't want to burn my jeep. Thanks!
