I'm replying to my own post with a link to a thread I started. I've used this device a lot in the last year and it is very helpful. I have it programmed to turn on/off the front inner HIDs, frount outer HIDs and a roof mounted LED and I have three open channels that I haven not utilized yet.
With the press of one button they all turn off. I suggest keeping one eye closed shortly before terminating them all at once to help with the transition from mass light to normal driving lights.

Disclaimer: I bought my unit and have no connections to the manufacture. I like it a lot, it's worked well for me and I've never blinded any of you.
