Halogen and other bright headlights are found on later model cars. Although they do a much better job illuminating the road, they can be quite blinding to oncoming traffic and pedestrians. As a result, their beam coverage is often "cut-off" lower than you find with traditional headlights.
Correspondingly, the amount of light directed at signs mounted above the beam cut-off is also reduced. Signs can appear duller.
To address this, higher grade Retroreflective signs and sign Post Panels and Blazers are often used. Blazers use diamond grade reflective sheeting.
Post Panels use engineer grade films with an eye catching striped design. |
