Xenon Headlight w/ Auto Adjust Level

[EKS PYB]

I am so sure that my headlights adjusts automatically whenever I start my engine, the headlights would move up until centered before.

But when I changed both blinker bulbs on the headlights a week ago, whenever I turn on the engine and turn the lights on, the headlights don't move anymore.

Did I break anything? I remembered to plug everything back in. Wait, does it adjust the minute I turn on the engine even if the lights aren't on and maybe that's why I don't see it. Or it will only adjust when the headlights are turned on and therefore, I should see it, right?

Please advice!
