oh i should explain better.
The tail lamp, brake lamp and both blinkers works fine.
But in my state, the license plate lamp is required, which i dont have right now.
I just wanted to make it cool in the dark.
So heres the problem again.
I got the power from blue wire(which is the hot wire for the tail lamp), and placed a silicon diode, and then wired to LED and LED to grounding.
but the LED lit like blue(LED itself was white) and it blue. i tried with 2pin LED, and same thing happened. So i figured that the current is too strong.
