Would it be possible to hook a relay to the light circuit for control and use a 30 amp relay to the HID ballasts ?
I hate using an under rated control device. Time will tell when your feed wire melts
I could do that, but why would I? With the PDM, I run a single switched source instead of a bunch of relays. It's essentially a solid state fuse box that has programmable power on/off delays. The PDM provides 6 circuits, up to 60A…so I'm not sure where you're getting the the idea that it's under rated. The DDM xenon peaks as 6A and tapers off to ~3.4A once it's running. I only run one ballast, in the event it fails, I can still turn my halogen high beam on.
