Used the above after looking at guides on how to try and identify quality ballasts - while I'm not saying these are top quality they do seem ok. I did swap out the 6000k for 4300k as I don't want a blue tinge.
No on 407's they are a gamble. I fitted them to my first 407 and had no problems other than a warning when they switched off,same as lazydave but because of all the issues others had I didn't fit them to my last one and won't be fitting to this one. Which is a shame as I loved them
some get away with it others don't. No pattern to it as far as i know. I had them in my first 407 and apart from an error message when they switched off they were faultless for years. BUT because of people having problems i wouldnt fit them to my second or even now my third 407.
