remind me, where did you get the 1 last time?
iirc it was a dealer, so will be 4300k temperature
that is 6000, so will be a very different colour to the one you have.
The chinese ebay specials like that - I have seen reports of not working at all, working for a short time, taking minutes to come on, flickering, or just causing fires.
And if none of those happen....your just left with poorer illumination than the proper lamps.
I bought a pair of chinese ones for my old car, and to be honest, they were ok, the old ones illuminated better, but the different colour masked it.
in your position, it would be 1 x new lamp from phillips or osram, cheapest online source I can find
such as
