Fuel low light issue

[Kitt]

So i was trying to change the factory bulb for the fuel low lamp with a LED one and the problem started: The LED was on all the time even do there was fuel on the tank, installed back the stock bulb and there was no light on it. Tested the bulb and it works fine, tested the contacts for the bulb and i got 12v as usual. Did i fried something in the ECU??? Please tell me i didn't:cry:

sounds like something fried to me, have you swapped out leds before?

I thought with each led you had to use a mathematical formula to determine which resitor you would need for the led, each led needs a resistor...

and it has one, that bulb is different than all the other ones, it is bigger and it says 3W on it, i assume it is 3 watts. Do you think that it goes to the ECU or to the fuel tank??

Just to let you all know, I fixed it by reseating the power by moving the key to on - lock - on and disconnecting the battery, let it there for 20 minutes, re connected the battery and it worked!!! i've never been so happy of seeing my fuel low light on!!!
