Hi, Please refer to the link as below which location tried to initialize a dom event for light. http://mxr.mozilla.org/mozilla-central/source/dom/system/nsDeviceSensors.cpp#239
Then refer to "objdir-gonk/dom/bindings/DeviceLightEvent.cpp" to know what it's constructor function did.

I have been searching around the answer for the questions as I posted above. However, there is no clear reply yet. Any feedback will be very welcome.
