He re-engineered his lights for LEDs and is now blowing fuses. You either have a short to ground or the LEDs are drawing too much current because there is not enough resistance in the circuit now. Regular bulbs have more resistance than LEDs. You car is engineered for incandesant bulbs. Either reverse everything you did and return it to stock, isolate the problem wire, or insert a resistor into the circuit. I recommend returning it to stock
