Brake Light Bulb- Which one?

[bughusband]

Hi there. I'm a newbie here and have done some searching. My wife owns a 2007 New Beetle. (2.5 litre auto)

The right rear brake light is out. I've found a thread with instructions on how to replace the bulb and in that thread someone says that it's an 1157 bulb that I need. However, in another thread that I found, they say not to use the 1157. (mentions a 7528).

Which bulb is it? Calls to my local dealer are no help at all. According to the parts dept. I can only get the bulb from them.

Also, it the centre brake light (on the hatch) isn't working either. Can that LED unit only be bought through the VW dealer?

Thanks
