UV Degradation over time. Analysis of a particular case showed a 3,000 candela reading on low beam and 7,000 candela reading on high beam. Degradation of the hard coat on the polycarbonate (PC) is blocking the transmission of light from the internal headlamp bulb. When the headlight lens ...
The functioning/no functioning test for phototransistors can be verified by using a simple pragmatic illumination (e.g., bulb, torch). No quantitative results needed. The functioning/no functioning test must only be done after the stress tests. It is not necessary for intermediate read-outs. ...
