How to use HID lights as Daytime Running Lights
Disclaimer: I am not responsible for any damage to your car, your electrical system and/or your stock lighting/HID system. It is recommended that you have at least basic wiring skills knowledge to do this mod. Do this mod at your own risk. Also this mod is for Cobalts whose daytime running light are in the headlamp position, NOT parking lamp position. The car used in this modification is a 2009 SS coupe.
Now that is out the way, let's get to business. This simple mod (dasaints bridge) will allow you to keep use of your DRLs with your HID kit without purchasing a higher price DRL module.
You will need:
Two pigtail fuses
Wire strippers/crimps
A piece of 16 gauge wire
First step is access your underhood fuse box
remove the DRL fuse located here
Remove left low beam fuse here
Insert the pig tail fuses ( don't forget to insert the fuse in them)
Strip about a 2 inch piece of 16 gauge wire at both ends
Insert the ends of the wire into each of the pigtails and crimp
Make sure your connections are tight
Now put you keys in the run position, put the car in reverse and lower the handbrakes (please do not try for the darwin award)
Your HID lights should now come on as DRLs

Looks good but when i wired my lights they always turn on without doing that. But i did use quick connects to get some power for the halos if i remember correctly and i got the same result. Maybe yours is better because you dont have to use quick connects and maybe damage the wires of the lights

To OP, what fuses you used? Same ones?
And what does the connection does?
Wouldn't you required to connect both low beam fuses?
Can one send enough power? ie 55w ballast?

This but i remember reading somewhere that it might damage the ballast I think, because they are not running at full power.

running the ballast on anything less than 12 volts is not good. I kept mines off until I did this mod

Mine came on then went off iirc. The low power on the denso ballast I have didnt work. So I wasnt chancing it. I just provided the requested power
Might be my ballast or relay harness, not sure to be honest.

Oh ok, but then you are using 2 fuses of 10? Per slot correct?
Mine turns on too. But I read that ppl take out the drl fuse so they wont come up and wont damage the ballasts. I just turn it off manually even though mine stayed on if I forget to turn them off, I will see the reflection of them when im behind another car lol . But I knew about the issue that drl do not provide the sufficient power to the ballast and it my damage them. Im on morimoto ballasts.
