Soldato
.......but what if it isn't actually 'dark'.
I say this because I like using them when it's a bit cloudy, as I have a dark car. Dont want to put dipped on as the HID's make you look like a tool.
I tend to use my headlights whenever it's a bit grey outside. I like to be seen. HIDs don't make you look like a tool if they're fitted and adjusted correctly.
