cheers for the replies lads, funny you should say that farhan as i ordered cosmos blue shortly after making this thread and now i have them fitted. very very happy with the results! the blueness is perfect and exactly what i wanted. not that bright tbh. no where near as bright as the extreme brilliance blue ones i had from halfords. but they still give out enough light. and the colour is perfect, not as blue as 8k obviously but they are more than blue enough for me. they beat the blueness of white LEDs and not a hint of yellow. alot subtler than HIDs which is what i wanted. would recomend to anyone for a great colour and a unbelievable price. cant say anything about the durability as only had them in a day lol. but even if they only last 6 months the price is right.
