What do you mean? I don't have an NCV3, but I really don't understand what the dome lights have to do with the alarm...

I had an aftermarket alarm installed which senses a load on the battery to trigger when the doors are opened. With the led lights the load is not enough for the alarm to sense. The vibration sensor still works.

I don't know if this is helpful at this point but I had a similar problem with LED bulb glow. After a little research I found that I could resolve the problem by increasing the size of my LED bulb. I ordered my bulbs online from superbrightleds.com

Using this bulb in just the first position (the fixture with the switch) eliminated the glow problem:

4210-xHP3: 3 High Power LED Festoon bulb | $ 7.95 |
4210-WWHP3: Warm White

I kept the original smaller LEDs in the remaining three fixtures in the cargo area:

4211-x6: 6 LED Festoon bulb | $ 3.70 |
4211-NW6: Natural White
-----------------------------------------------------

(and by smaller I mean in terms of power not physical size)

The show noting of the off "glow" mentioned with others. They are bright as the stock 15W, about the same color temp as those incandescent lamps, and as I said they do not have any residual ON problem when they should be of and they do not cause any "bulb out" issues in the Sprinter.

One of the advantages to a regulated LED light is that it is has the same brightness over the entire range of vehicle voltage usually 12.5-14.2V and they are not damaged by use at 14V unlike some cheap ones made for "12V". I see a numebr of these bulbs that are just a string of smaller 1.2V LEDS in series with a resistor to set the total current for whatever voltage they assumed from the vehicle. I have found such LED produce very different light depending on the supply voltage.

Note, the stock festoon bulb is closer to 39mm long but the lamp holder/contact tabs are easily re-bent in the MB dome light to fit and hold them.
I'm reviving this thread before ordering these replacement bulbs for a 2015 Sprinter.

Any other recommendations?

I've noticed the same thing in my '14 crew when I installed SuperBrightLED'S. It doesn't seem to have caused any problems so far; LED's use so little current at normal brightness that I can't imagine them using enough to cause a problem under these circumstances.

Funny, I noticed the glow recently and here's a thread...
There are nights when it bugs me and nights when it doesn't but it does make me wonder how much power is being lost/consumed.
FWIW, I didn't notice it when I replaced the factory incandescent with super bright LED's but I do now with the 'canbus safe' warm white.
My intent was to reduce the power consumption as I use the interior lights for fairly long periods when camping.
Wondering if anyone else out there has run into this issue recently(?) Would like to see any updates.

The current "loss" that triggers the LEDs' glow was there with incandescents, too... it just didn't make them hot enough to be visible.

The *amount* of loss has not changed.

Default Re: LED cargo lights

While on the subject of cargo lights, my '07 has three lights in the cargo area. The one at the very back has a switch and controls all three. I need the rear one as that space is unto it's self, i.e., walled off from the living area. The middle light I can live without but wish the one over the sliding door was on a switch to turn it on when the sliding door was opened. I really don't think I want to go there (too technical for my simple brain) but wondered if anyone had done anything on that order. And can I just cut the wires on the two I don't plan to use?
