2012 / Headlights and Tail lights Stoped Working

[George Ingraham]

Driving down the road and both the head lights and tail lights completely went out. Then on my way home they came back on all by themselves.. 

 

I suspect it likely that will happen again as I have done nothing to try and fix, as have no idea what would even cause this. 

 

Any help greatly appreciated !

Any recent exposure to heavy rains or high pressure car washes?  Could be water intrusion into the battery junction box or the BCM.

 

Is the lighting halogen or HID?  Stock or modified?

If you are using auto headlights,  The next time it happens turn the lights on manually.  Both the headlights and tail lights at the same time could point to BCM, Headlight Switch, Light sensor on the dash. 

Switch tells the BCM to turn on or of the lights.  Sensor tells the BCM to turn on or off the lights if the switch is in the auto setting.
