He said that xenon headlamps installed in brand-new cars are allowed by law thanks to the lens that prevent the scattering of light.
However, some motorists have their headlights replaced with xenon projectors, of which prices have declined sharply from over Bt10,000 to a few thousand baht. With the projectors, light scatter to all directions and could lead to accidents. Such retrofit thus requires endorsement from Land Transport Department's offices, he said. Without permission, they are liable to maximum fine of Bt2,000.
Traffic police data shows about 1.3 million violators in 2014 and 1.4 million in 2015.
