As has been stated on many 'replace H4's with LED' threads on here, such bulb only replacement is illegal, an MOT failure and will very likely void insurance should you have an accident... as well as potentially being inconsiderate to other road users...
On balance, personally, I decided to stick with high performamce (Phillips/Osram) direct replacements rather than run the risk of driving around illegally and, now, having to swap out at MOT time.
