If you're referring to the lower bumper cover lamps, there is only up & down adjustment. On the bottom of the assembly you will see a round "wheel" with gear teeth. If you turn that wheel it moves the bulb up or down in the housing. Best bet is to get the front end up on jack stands or ramps, and start the job in daylight, locate the adjustment wheel and do your adjusting after it gets dark. There is a pretty significant difference between the highest and lowest setting.
