A very important inspection of the test and an on road legal requirement is the lighting. All bulbs and light unit condition are looked at for working condition and general condition, also headlamp are normally requiring adjustment due to the vibration of the road surface in normal use. Lights working and brightness is the important bit and should be good. At NICE MOTORS we replace and adjust as required with good quality bulbs and units to keep you save and visible on the road in the day and night.
