I've got Catz dual beam H4 5500k kit, which've been serving me for about 4 or even 5 years, and today the passenger side suddenly became violet instead of white.... now it looks more like 6-8000 Kelvin bulb hence not efficient at all at doing it's job

I recall driving in deep puddles earlier the day, could this be of any effect on the ballast/igniter/bulb? I have everything well hidden and it's protected from water, besides the kit itself has good isolation

or does the changing color indicate the wear on the bulb and I just need a new one? It's easy to tell with halogens, because they just stop working in such cases :p

You can swap the bulbs side-to-side to confirm whether it's the bulb or ballast, but generally a color shift in the bulb means it's shot.

Def sounds like the bulb is on it's final breaths to me. HiD bulbs do that.

here goes another order for overnight parts from Japan :lol:

thanks guys
