It has a high degree of all round visibility. The dual lines of light visible from the rear offer other traffic participants more perspective, allowing them to judge your position better. That makes you safer. What is LineTec? When a rear light shines only as a single point of light, other traffic participants approaching a bicycle at night from behind can estimate the distance only inadequately. This changes when the rear light becomes a wide light strip: Now the distance can be percieved much more accurately, because the light strip emits a "spatial light" in the 'spaceless' dark. This special technology that creats a homogenous light strip from one high output LED is called LineTec.
