The tests were made for the Ministry of Transportation the Committee of Warning
Devices and Safety
1. GENERAL
The butterfly ( active solar powered butterfly ) is an optical vertical guiding and warning device
that reflects incident light by means of retroreflectors in order to warn, guide and inform
the road users.
Model: YH-HL
