easy, 3 relays. 2 for the H4 setup and another activated off the H1's.
Not only is increasing the wattage/voltage to the lights important, but getting the beam pattern as well. The Hella E-codes in either a glass reflector pattern (E1) or the clear lense reflector pattern (E4) or even Cibies really put the light where you need it and not in the eyes of on-coming drivers. Just the 2 E4 Hella's in my Daytona with Relays would throw more light on the ground than HID Beemer's and Acura's back in the mid 2000's. I had them paired with Hella 300 driving lights that were purposely put on the wrong side of the car to throw light at the apexes of corners. Unfortunately you can't get the 300's anymore
Me and a lot of Lambo owners are sad about that.
