The power LED's do not power up nor does the switch power the head lamp. The head lamp is power by the CA output power jack and the throttle button is the on and off switch for it.
Both teh power LEDs and the CA power jack are battery voltage, and have nothing to do with the throttle power, which is a separate 5V from the controller.
Also, there isn't any way the CA software version or settings could prevent the LEDs or light from working, so you have a hardware problem somewhere causing that.
If the LEDs adn light are not working, but the CA is powered up, then it isn't likely to be simply a battery voltage short-out to something else as I originally suggested.
But it could be a broken ground as Teklektik mentions, if the headlight also uses the throttle ground as a return like the throttle and power meter LEDs do.
A broken ground at the throttle cable or connector or inside the throttle or controller could prevent all three from working, as long as that ground is common to all three.
If the headlight has it's own ground return, then it's probably not a broken ground.
To test this, you need to power the whole system off, then use a multimeter on continuity, and measure with the red lead on the ground connection (inside the throttle if possible), and the black lead to the battery negative terminal.
If you get a continuity beep or near-zero ohms, then the ground is fine.
Then you can test for a short between the throttle's 5V and the battery-voltage wire to the throttle body (probably the purple wire).
