okay i've recently got my HIDS spw hella 7500k from impex motorsports in san gabriel blvd (so. cal) and when i turn on my HID, it flahes once, then it's normal.......is that right? is it suppose to flash once or something? and also, i kinda see a lot of the floor and not really on the street...........do i aim the bulb higher? and how do i do that?
