Since there is effectively no naturally-occurring infrared (IR) in the night sky but lots of it during the day (even when overcast), would an IR photodetector be a possible solution?

with my hobby projects I use a 10k pot,1k safety resistor and 10k photo cell
you can add a little "debounce delay " for the headlights and cal with the pot
Code:LDR=1 'POWER UP LIGHT SENSOR Pause 20 ADCIN 0,NIGHT 'READ AN1 & STORE IN NIGHT VAR PAUSE 250 IF NIGHT=<400 then IT'S DAY SO DO THIS IT'S NIGHT SO DO THIS Pause 25 LDR=0 'MAKE SURE LDR/ADCIN POWER IS OFF
" be nice it's people like me that make people like you look smart"
yes I read the datasheet, of the 300 pages I understood 10

Here is an example of a delay to avoid headlight induced lights off.
Code:LIGHTS VAR PORTA.0 DAY VAR PORTA.1 MAIN: IF DAY = 1 THEN PAUSE 10 IF DAY = 1 THEN LIGHTS = 0 ELSE ENDIF ENDIF LIGHTS = 1 GOTO MAIN END
