$20 or less for a decent head lamp and you will find your self using it for more than smoking at night ,another option is a pedestal lite with 3 swivel lites. Just put Led lites up in the carport and hooked up a Hyper Tough wireless remote to turn them on and off with.
I use a headlamp, also got some high powered flash lights I just prop up as needed..
Though my smoker is on the porch or behind the garage where the lights are..so I guess that is cheating. I do suggest a headlamp though, you can't really go wrong owning on..especially if you own dogs who like to go outside at night alot!
