Car headlight plastic as a kind of evidence often can be seen in traffic accidents and some other cases. We tested 20 brands of car headlight plastic using gel chromatography. The data were processed using the Statistical Package for the Social Sciences (SPSS) one-way analysis of variance (ANOVA) and the discrimination rate was 97.14%. This indicated that we could discriminate between different headlights by the molecular weight of their headlight plastic. Gel permeation chromatography is an effective method of discriminating between headlights, particularly in the case of a traffic accident.
