+Register two events coming from source `22`. Make the brick status light up  when
+the events of `0` and `1` are _raised_.
+
+```blocks
+const statusLighter = 22;
+
+control.runInParallel(() => {
+    for (let i = 0; i < 2; i++) {
+        pause(1000);
+        control.raiseEvent(statusLighter, i);
+    }
+})
+
+control.onEvent(statusLighter, 0, () => {
+    brick.setStatusLight(StatusLight.OrangePulse)
+})
+
+control.onEvent(statusLighter, 1, () => {
+    brick.setStatusLight(StatusLight.GreenPulse)
+})
+```
