It's likely the stator or voltage regulator . Step one is to measure the voltage across the battery with the lights off and the motor reved up to about 2000 rpm. The voltage should be between 13.5 - 14.8 VDC. Turn the lights on and redo the same test, the voltage should still be in the same range. If not you will need to test the stator and regulator. The lightsput about an 8 amp load on the charging system.

Sounds like the stator is taking a dump. Do the voltage tests and still don't discount the stator even if it does pass the test.
