When I removed part of the trim covers under the dashboard some weeks ago, I noticed some kind of “electric” device (see right side of the trim). Of course, I was curious. Clearly a small light to illuminate your toes ;) .

Googling, it seems this company (TLC Redditch) makes lighting systems of the automotive sector and so on.
I dismounted it completely:

The yellow square is a LED (Light Emitting Diode). Beware: the lowest picture is the same as that above, but underside.

One small LED shining through a plastic window and through such a small hole, probably fit for purpose?

When does it light?
  • Not when you open the door
  • Not when you push the driver or passenger roof light button
  • Yes, when you press the center roof button “interior lights”

Both sides have such a light.
 
I don't have the puddle & ambient lights, so will have to check if I have a different trim panel or the same with a blanking piece.
 
Just checked mine - I obviously didn't get this option (cheapskate me) so my feet will remain in the dark. There is an easy fix using the power outlet in the footwell and the INT 1 and INT 2 switch. Could make it blue or funky colours. @Jean Mercier - really appreciate your ongoing efforts to inform us.
 
Until @Jean Mercier has his Grenadier completely disassembled and laid out I won’t be impressed. Taking things apart in dribs and drabs is lazy.
RE: Jean Mercier, there is an old joke about the man presented with an alien technology device that can provide unlimited free energy and also guarantee world peace. Does he:
1. Give it to the President?
2. Give it to the head of the United Nations?
3. Take it apart to see how it works😊

(And, Thanks to Jean for the service he provides for all of us on this forum.)

I think @DCPU is even better than me: he disassembles, analyzes and improves things, much more than I do.
I always have some idea behind what I do: making the auxiliary power points available, adding a supplementary USB charging point, adding a wireless charger for my phone or a DC/AC inverter, sometimes going too fast and dirty. :eek:

I think you and DCPU are both top contributors. You both help pave the way in seeing what can be done with these vehicles by way of practical, home based improvements.

100%..... but both are also responsible for sending our delivery/anxiety frustrations through the roof.. like... where's mine to play with...😂
 
I just need to investigate a reason for me to need footlights. And when my car arrives , I can go exploring down there!
 
You wouldn't happen to have a shovel and a bag of lime in the boot by any chance?
Not in the boot right now , but can heave them in any time
Bodies as well. 6 in the old Merc.
 
Try hard, fail fast 😎
It is all about priorities: Make all that traces go away at any cost.
 
Don’t worry Dave, just a keen gardener with acidic soil. Nothing to see here 🤫

Hi Jean, this is the exact thread I was looking for. What did you end up doing with the light or the outlet? I would like to possibly reposition the LED pcb to light the key hole, or re-wire the existing footwell light with an additional LED above the key hole. Do you happen to know the voltage and amps on that exact circuit?
Thanks

I'm working on the exact same thing! Maybe it's just because it's winter in the northern hemisphere, but I am aggravated beyond rationality that there's not a light around the keyhole and I have to carefully look each time I start the car at night. I was thinking of making a flashing that fits above the keyhole and shines an LED down where it's needed.

I found this thread and SPECULATE that the circuitry in the the photo is a transistor, capacitor, resistor, and diode that all work together to make the LED dim slowly when the car doors close or the lights are turned off. ( A nice feature, but hardly necessary for a utility vehicle. ) What I have not yet investigated is:

1. do all Grenadiers have this footwell light that could be tapped into, or is it just the Fieldmaster level of trim?
2. is it straight 12v that runs to this LED (switched by the computer/ADAS) or is it some kind of fly by wire signal that activates the LED? (easy to test with a multimeter, I just have not yet done it)
3 would running an 12v LED in parallel to this circuit to the Keyhole area have any adverse effects?
