I don't smoke cigarettes, but if I did I would light them with this Solar Spark Lighter.
...This is cool enough to make Fred Flinstone jealous.
Not only will this device allow you to harness the power of the sun to light your addiction... it will also make you the center of attention at any campsite. Unlike traditional lighters, this solar-lighter will work in windy conditions and never need to be refilled with fuel.
A spring mounted holder ensures your cigarette is always at the focal point of the sun's reflected rays, and the $8 mirror is made of plastic so it won't immediately shatter if dropped. It's also the perfect camping accessory if you've never had much luck rubbing two sticks together to start a fire.
