u never knew how many ppl in the car from oncoming traffic cursing you..
try drive up to a flat wall and see your headlight beam pattern...was it on the left or the right kind of beam pattern in this picture
even on halogen reflector...the oem original good condition headlight still do have obvious "cut-off" line visible like on the right... and good hotspot in the middle near the cut-off line...
if the cut-off line is blurry and many light streak shining upwards, means thats the glare...and total not acceptable to be used on the road...
**cut-off line pattern depends on LHD/RHD and or EU or DOT pattern...
**example of cut-off line pattern:
1- RHD EU \___
2- LHD EU ___/
3- RHD DOT -----\____
4- LHD DOT ____/-----
this applied to reflector based and projector based headlight...
