We offer a special optical system for traffic signal heads by which the undesirable and dangerous phantom effect is optimally suppressed.

Normally traffic signal heads without a phantom reducing lens system may give impression to drivers that all 2 lenses are illuminated if the sin shines directly on the signal face. This situation of course leads to confusion sometimes resulting in accidents.

Therefore, this type of optics is of vital importance for safety purposed for the drivers. Halogen lamps are used with specific type.
