It is used for testing the luminous intensity and the illuminating position (or the optical axis deviation) of headlight of high/low beam by hand-operated measurement ;The advanced configuration optical system is used, and the characteristic of light distribution for headlight under test can be shown in the screen;It is easy to be observed and adjusted. Both the high beam and the low beam can be tested;The measured result can be output via the digital/analogue signal.
