Retrofit ceiling fan light - bypass ballast

I'm trying to change my ceiling fan light over from a fluorescent light to a standard screw socket light since a replacement ballast isn't made anymore. However, there are 4 wires that go into the existing ballast. What are the extra 2 wires for? I was expecting a black wire and a white wire only. What are the brown (ground?) and orange wires for?

Thanks in advance. Name:  20141127_111902.jpg

What is the make and model of fan? If we know that we may be able too look up schematics of the fan or maybe someone else has the same model and can tell you more about the fan. Thank you!

In addition to HC's requested information what voltages do you get using a multimeter to measure between the various wires.

There would have to be four wires minimum into a ballast.
The white and black are the 120v into the ballast.
The other two are the high voltage that goes to the tube.
