Wiring my Halo lights as Daytime Running Lights
Since I now have the computer control of my DRL's disabled, I need a way to energize the Halo lights as the new DRLs. To accomplish this I used a relay. relays come in various flavors. The ideal relay would be a normally closed relay, which means the circuit attached to it's leads is on until the relay is energized, then the circuit opens, or shuts off. I didn't have a normally closed relay in my garage, so I used a 5 pin relay that I had lying around. Simply ignore the 87 pin and put some heat shrink on it to isolate it because it is not used for our purposes. You can see in the diagram that follows that this relay can be wired either normally open, or normally closed.

By using pin 30 and 87a, I have a normally closed relay. When the coil leads (85 and 86) are energized the relay opens and shuts off that circuit. I took 12 volt power to pin 86 from the green parking light wire, and the 85 pin is ground. When the parking lights or headlights are turned on, the relay energizes and suts off power to the DRLs. All I had to do was supply power to terminal 30 whenever the car ignition was turned on. I tapped into the cig. circuit under the dash using an "add a circuit" wire. I also installed a lighted on/off switch after the fuse. This allows me to cut the DRL lights off whenever I want to.
This power feeds the red wire on my Halos...which light the white LEDs, thus becoming DRLs. Since my Halos are switchback type, I took power from the turn signal wire (red wire on 1157 socket) and tied it to the Halo yellow lead. This now operates the Halos as turn signals, whether the DRL's are on or off.
You can see the Red, Black (ground) and yellow leads from the Halos in this pic.

I know it might be confusing. I forgot to take pics of the relay wired up, but I did a hand schematic to kind of give you and idea of how the circuit operates.
