What Timer Module?
1x500kUF capacitor
1xdiod
1x5 way relay
That's the timer
if I have the capacity, would have mass production & make profit liao.
500kUF to kumpul battery so it result in slow dim timer module.
1 way diod to refrain other component in the car to draw power from the 500kUF temporary "battery"
5 way relay as below:
+ for main power
- for ground
Switch ON to connect door swith
Switch OFF to connect alternator
Output connect DIOD then Capacitor then LED
When door switch is triggered, relay turn on output, diod take 1 way current to charge up capacitor, then LED lite up
When door closed, relay stop output. Diod refrain current flow back, capacitor continue supply power to LED until power drained
If alternator start charging(engine started), relay cut off supply to diod, capacitor continue supply power to LED until capacitor power drained
To have instant switch off LED after engine start, can add in another relay AFTER capacitor. When alternator start charging, staright away cut off power from capacitor.
Time to get down to busines liao
Your electrical knowledge not bad.. 1x500kUF capacitor

Well, i can get it work with 3 resistors and 2 transistor and 1 cap with more accurate timing module with FOC.
