Well the subject pretty much sums it up...i'm looking for some fog lights for my 87' ram and someone told me about a new "rechargeable" fog light that has its own battery system. He might have been telling an old wives tale, but he says they'll plug up to your cigarette lighter while your driving down the road and charge em' up, then when it comes time to use them you don't have to worry about your truck battery going dead if your not running it.

Has anyone heard of this or know where i can find them? Any suggestions on this or what kind i might want to try would be appreciated...

Thanks.

Nathan
