Need Help!!! "Active Headlamps Inopertive"

I posted this on CLS forum bit looks like no one has an answer.

The other day I changed my headlamp bulbs to Phillips 6000k S2S bulbs. After the install, the headlight works great but I got a message/warning light that say "ACTIVE HEADLAMPS INOPERTIVE".

All I did was just change the bulbs.

Anyone know why and how I can get this message reset?

I drive 2008 CLS550.

Gonna sound crazy but start the car, keep it in park, turn steering wheel all the way to the right, and hold for a few seconds. Then turn steering wheel all the back to the left and hold for a few seconds.

You have to do this whenever you unhook the batter as well.

Isn't this resetting ECU?

Would this get rid of the warning light?

I tried. It did not work. Can you be little more specific?
