Upgraded Interior lighting M3... Thoughts?

[Scott Francis]

Hi All,

Follow on from my post No.200

I Attach the circuit diagram for this ambient light sensing circuit. This takes a very small amount of power (Max 3mA) form the ambient light positive feed wire and uses it to switch a relay connected to a much bigger 12V supply (i.e. cigarette lighter)
Used in my Model 3 to switch Basenor RGB Led kit on and off with the ambient footwell lights.

Feel free to copy the circuit and use it.
I will put together & post kits of parts for anyone who is interested, and even build the board for you if you like (for a small fee!)

Disclaimer - If you build this and plug it onto your Tesla - it is at your own risk (obviously!).

Relay HFD23/012-1ZS
Diode 1N4143
Resistors standard 0.25w 1%
Cap 0.47uF Metal film
Transistor BC337-40

Happy tinkering!

Hi Jeremy,

I am doing an Ambient light install with the Hansshop Laser kit but I want it to turn off with the car not having to do it manually. Is your offer of making your relay kit still valid if so I would like one please how do I go about paying you?

Thanks

Scott
