forget here to mention that on petrol currently car is working fine no issue with running on petrol only the light is not showing.

If everything is working fine and car is converting to cng etc. then only led can be bad inside the switch.

how could I check that LED gonna fused..!?
how ever I have open the circuit as well but it have very criticle print board.
and I am sure in current market I will not found such genuine suzuki switch.
I have see there on it's port/cable it will have 4 colors of wire:
- red
- black
- grey
- blue

red & black I understand for which purpose they are. rest of the wires I am not getting from where I cn locate them...

You have to dismantle it completely.
Check if led is getting voltages of not.

[nomicandi1985]

do you have any confirmation that does these are 12 V. I mean If I try to give them directly 12V from batter to test the LED it doesn't harmful for them..!

[Hassan1991]

No. They would be 1.5-3v led.
Just check it with multimeter. No need to apply voltages direct to led.

[nomicandi1985]

hmm ok let me try it with digital meter. else I will try to make manual pencil cell battery specially for checking purpose.
