The headlight switch switches the ground side. The bulbs have power going to them and then the switch makes or breaks ground to the other side. The DRL relay pulses that ground making it look like the bulbs are being run at 1/2 voltage. The relay kit should make it where the other side of the feed is ground or no connection, not the pulsed ground.
