The Denalis use ~10 watts (0.83 amps at 12 volts DC) per lamp so that would be ~20watts / ~1.6a on the low beam circuit plus whatever minimal draw the relay has. Since I run the Denalis anyway the power I send to them wouldn't be wasted like it would be with a resistor.
This one should get multiple viewpoints from people here...
If you do this I'd use a blocking diode to prevent feedback to the ECU/ZFE when you tap into this circuit.
