I just put 3157 LED's on my 09 charger. I like them, too, but there is a down side to mine, anyway. Because the electrical load is less with the LED's, it blinks like you have a bulb out, much faster than with the oem incandescents. Sylvania says something on their website, about maybe needing a "load equalizer" or some such thing, but I couldn't find any more info than that. They're a little spendy compared to incandescents, but they appear really well made and should last for a very long time. I've left mine in for now, I figure I'll see if the fast blinking thing continues to bother me.
