I've decided NOT to install a retrofitted housing for 3 reasons.
First, I have driven for about 1500km with the H.I.D. kit, at daytime and at night. I did not get one reaction from other drivers that i'm blinding them. It seems not to bother them at all. at one time I was behind a cop bike, he gave me a friendly wave as I passed by him. No pullover, no bad reaction.
second, it is a fact that the standard housing scatters the light a little bit, but I feel more safe at night, knowing that other drivers sertenly spot me when I'm coming up from behind them. this was not allways the case with my standard lightbulb.
third, the scatterd light reflects like hell on the roadsigns 50m in front of me, making them a lot more readable at night.
I appreciate the effort for convincing me to do the retrofit, but as I see it, it has more advantages than disadvantages so I'm keeping the standard housing.
