I have tried the regular and it's too dark at night, I have tried the 'brighter night' timecyc.dat and it is too light! Can you do one that is half way between the regular and this brighter timecyc.dat. That way I think it would still be dark, but you could see where you were going. I mean, night time in LA is darker than daytime, but it's not pitch black till you get to the suburbs!
Sorry for being fussy!
