judging by the backslashes I'm assuming this was in a PHP variable.

Here's what you need.
<input type=\"text\" id=\"cartId\" value=\"04 1234 1234\" name=\"cartId\" class=\"required2\" onfocus=\"this.value='';\">

That removed the text when someone tabs to the box, great!  

But as above I have a class showing the text as light gray, when they start typing in the box it is light gray as well, I'd like the typed text to be black.

Any thoughts?
<input type=\"text\" id=\"cartId\" value=\"04 1234 1234\" name=\"cartId\" class=\"required2\" onfocus=\"this.value=''; this.className='required3';\">

then write your css class of "required3" to style it how you want it
