Hello everyone!
I'm doing a project in my car where I have those kind of courtesy lights on your feet when you open the doors.
To achieve this I used a relay, the switch to turn the relay on is the lights on the roof and the power for the LEDs comes from a piggyback fuse from the fuse box.
With this the LEDs turn on when I open the doors and turn off when I close them, it works perfectly.
The only problem is the amount of buzzing the relay makes when turning on or off.
Sounds like a spring touching metal.
I don't know if this is relevant but the roof lights that serve as a switch, when I open the door, they have somewhat of a dimming, they don't turn on instantly, they dimm from off to fully bright in a couple of seconds instead of instantly.
Could this be the problem, because I'm not feeding 12v instantly to the relay and the step from 0 to 12v causes this?
Thanks in advance
