In traffic it is necessary to be able to cross safely at busy intersections. To be able to guarantee this, a good and clear traffic light is needed. In addition to the main traffic light, an underlight is often used. The bottom light is a smaller traffic light that is often mounted on the traffic mast and ensures that motorists and cyclists always use the traffic light properly and safely.


This underlight was designed and developed in its entirety by QDP for the company Hoeflake Infratechniek B.V. It was decided to make the housing of aluminum, as this is a light but very strong material. This means that the underlight can literally take a beating. In addition, the lenses are made of impact-resistant polycarbonate. This is also a strong material and therefore contributes to the strength of the product. Furthermore, it is possible to apply different templates in the underlight, making the underlight widely applicable.


Partly due to the choice of materials, a product has been realized that is resistant to all weather conditions and vandalism. It is therefore not possible to remove the light from the mast, because the mounting is hidden behind the lenses.

‘Hufterproof means as much as “resistant to vandalism”. The term is mainly applied to (the construction of) buildings, their design and (the attachment of) street furniture and works of art in public space.’
