HID Projector Relay

My question is y do i power both ballest up wit one relay???? Y cant i just make a relay for each..and if that is the case how is that done??? Cause all i've seen are ones for two ballest on one relay..... i have 9007 hi/low by the way...ok i got the relay down (i think) # 30 to battery wit fuse, 87 to one balles wit fuse, 85 & 86 both go the male connector i have wit a diode connected to both the Hi/Low Is that right??? If it is the question is do i still use a 30amp fuse for the battery and a 15 for the ballest??? All 12 gauge wire right I already have 1 10 watt, 10 ohm resitor per selenoid soldered on the selenoid wire .So i shoudl be fine right??? thanks sorry but i want to make sure i understand the wirein.

Why? You can use 2 relays if you want. I don't see the need Driving lamps are meant to supplement your high beams. If they are adjusted so that they do not blind oncoming traffic then they are not going to help your high beams out to much. Your relay wiring is correct
