Halo + LED interior lights

[T6Jay]

I can't comment on the current rating of the BCM other thanto say that it's rated for incandescent festoon bulbs, so if you've replaced those with LED bulbs then you shouldn't be exceeding the BCM current rating. If you wanted to be on the safe side you could replace the diode with another MOSFET switch module which would run in parallel with your MOSFET circuit. See attached diagram. That way there will be no appreciable load on the BCM

There was no filament lamps (it's T6.1), but Dellmassive seems to be saying the BCM will eat the 300mA for breakfast. If I find otherwise, I will add a MOSFET as you suggest, until then I will keep it simple. Thanks

the 7.5A is for T6

check to see if T6.1 is same.

The interior light circuit is fused at 7.5A, so thats the MAX you can switch through the BCM.

OK, so 300mA + one VW LED light is easy

You can use the "+12v timed BCM supply" or a AUX leisure battery supply (must all have common chassis grounds)

My existing lighting controller uses the leisure battery, so I'll stick with this. Leisure battery 0V is grounded.

(brown/red) - connection 1 main harness (BCM switched neg)
(red/black) - positive connection 1 main harness (BCM timed +12v)( 7.5A fuse 19 holder C)

This is what I have, it's a T6.1

you can use the Relay method or Mosfet method as @Mccoatup has shown above.

as for your idea . . . . what are you going to run on the Arduino?

how will you switch the light on/off?

The mosfet in the drawing is existing and working, all my lights work as described here;

Interior lights with touch screen and 3 way control. ( Arduino and Nextion)

Helloooo Long time no see ;) I was getting fed up not being able being able to dim or control my lighting (and a few other bits) from more than one location. Ended up adding a screen and an Arduino to the mix. Hoping to tie in with other Arduino fans and see what else we can control. I can do...

what is the purpose of this Diode?



View attachment 93254

The diode is to prevent the MOSFET from switching on BOTH of my courtesy lights (that's the idea anyway)

I went with a separate reading light in the end. But pleased with results. I added all three switches to the B Pillar as we have a 3/4 width Reimo fitted so the children can reach or passenger. Pleased with results and will change the live to the leisure battery once fitted.

Thanks again to @Dellmassive and @Deaky. Felt I owed you some pictures.

Looking good.

@BrenR What tape light did you use? Just doing my halo roof and looking for a good even glow all around the halo.

Also i've noticed 5m is a tiny bit short of all the way around.........has everyone just used the 5m tape and put up with the bit missing?
