No worries mate always here to advise and help where I can. Believe me lol I was in the same situation as you when looking for the whitest head light bulbs, saw the 5000k hyper whites n thought I'm bloody having them lol, then I read on and saw that they are for off road use only. So I went for the nearly as white cool blue intense instead. Our resident copper Clive will confirm that 5000k is a no no.
If you look here and scroll down it says 'Road Legal:No! These bulbs are not 'E' marked and are therefore not road legal and are for off road use only'
If you have a look at this thread here, a lot of us focus owners recently had a discussion on our bulb preferences:
As for the mtec cosmos blues, personally I'd give em a wide berth. I know a lot of people rate em, n a lot of fellow members have had them, but then I remember some of them posting photos of them actually appearing quite yellow in colour and said how they wasn't actually that bright and how they had some brown trouser moments on the unlit country roads. I believe some members replaced the mtecs with the osram nightbreaker plus or the osram cool blue intense.
Here are a few shots of mine:
Also if you look on Oxide's thread here:
Clive has recently bought the cool blue intense h1 and h7s same as me n posted photo's of his there.
The cree fog lighs you just linked should do nicely, as they are 6000k they are not E marked either, however as they are only fogs n not used as often as head lights, n fogs are not a legal requirement, you will get away with the cree fogs. Also as a wise man once said (Lenny), '[color=#282828][font=sans-serif]they may not be E Marked but they sure as hell have my quality approval on them[/font][/color]' so in my opinion that's all that matters lol. Again I know Clive has recently fitted the cree fogs n posted a photo of them in Oxide's mod thread.
As for the interior LEDs, the cree's will definitely be too bright lol. A decent 13smd or a 5smd should be sufficient enough. As for what colour to go for thats down to your personal choice. Personally I've gone for a full blue LED conversion, for inspiration, have a look at the last few pages of my own mod thread here:
So have a mooch at my interior lighting but wear your tanning goggles
Here's a preview
By the way, I have twin cree reverse lights fitted:
Think you'd agree they look the business lol and are a nice pure white, so I'm assuming the cree side lights you linked will be of the same effect.
As for the LED barrel, my bad mate I forgot you had a start button lol (jammy goit) you may still be able to fit one as you said but I'm affraid it's out of my range of expertise being only a MK2 owner lol.
