I just installed some diode dynamics hids and these are the first ones ive actually gotten to work on my truck. i need to adjust my cutoff and ive heard there is a way to adjust come screws to move them up and down. Could explain to me how to do that? also, i got 6k color and the passenger side looks it but the driver side looks about 4500k. is possible that the driver side need to be positioned a different way in the housing??
