I don't know why, but I always liked car chargers that light up when plugging them in. I think it's so you know it's working and not faulty when you think it's charging, but in any event, this one seems to work as expected. Not exactly the fastest charger: went on a drive for about 10 minutes including stop signs, stop lights and mild traffic and only charged my phone about 5% but I'm sure this could widely vary on a number of different circumstances. Seems a little slow on charging in my particular experience so far, but it works, lights up, and has two ports which I'm always a fan of. Overall a decent charger to get what you expect from it.
