This is what I got from Amazon. They are coming from China and are taking for freakin' ever to be delivered. There are many choices for the replacement bulbs. These have projector ends and are ideal for back-up lighting.

I had LED tail lights on my 09 Mercedes ML350 I'm still on the fence whether or not I'd see any benefit to changing to LEDs. The one that is cool is the one that is white for parking/driving lights but flashes yellow when you put on the turn signals. I am just confused as to what to look for in LED Bulbs to insure that I get the same level of brightness as the standard filiment bulbs.
