lou999,

Turn Bluetooth off and then back on in your smart phone.

The usual suspect with no headlight control is the decoder is not plugged in correctly.  Unplug the decoder from the PCB 8-pin socket and turn 180.  Number one pin goes in number one socket.

That not help, then test the connections Click Here for testing instructions.

   How to Click Here

Resetting the sound value decoder CVs to their factory default value is a two-step procedure.

   1)  Program CV 8 to 8
   2)  Cycle power to the decoder by turning power to the track off and back on

After about six-seconds upon restoring power the headlight and backup light will blink simultaneously 16 times indicating that the CVs were successfully reset. However, if sound or lights come on immediately upon restoring power, the decoder did not successfully reset. Repeat the two-step procedure.

For directional lighting (on/off)

Program
CV 33 = 1
CV 34 = 2
CV 49 = 129
CV 50 = 129

Oh, programming tracks are a dinosaur from the electro-past. The economi and subsequent Tsunamis don't need it.

Actually,

All makes of SoundTraxx decoders require using Programming Track when,
   Programming a short address to another short address
   Programming long address to another long address
   CV read

an aside
CV -  Configuration Variable
CVs - Configuration Variables

DCC decoder interchangeable nomenclature for
  CV 1 is Short address or 2-digit address or  Primary address
  Paired CV 17 and CV 18 is Long address or  4-digit address or  Extended address
