Modern headlamps are made from thermoplasts, which are very convenient materials for headlamp design. However, the poor thermomechanical properties of polymers can cause deformations, problems with the photometric properties, and sealing difficulties. In order to predict these deformations, standard methods were used and combined in a new approach for a quick and efficient evaluation of such headlamps. Thin-film resistance temperature detectors were employed at significant points on the headlamp housing to measure the temperature. The results were then used to determine a three-dimensional temperature field for the headlamp housing. This temperature field was subsequently used in a finite element method analysis to determine the deformations in the housing of the headlamp.
