Nowadays, energy resources are rapidly depleted and energy costs have risen. Therefore, the efficient use of energy resources has gained importance. The use of energy-saving fiber optic lighting systems has increased. In this study, PMMA and PS (crystal) polymers with high optical properties were used. The manufacture of fiber optic cable for the purpose of lighting by extrusion method was realized experimentally. The samples were manufactured at four different temperatures, three different

... uction rates and two different forms. Fiber optic cables with different lengths and forms were compared in terms of light intensity. As a result of the study, the sample manufactured in PMMA was found to be better than the samples in PS. The best light intensity values of PMMA samples were observed at 2.2 m min at 220 o C. On the other hand, the best light intensity was achieved in PS samples at 205 o C at 2.4 m/min. In addition, it was observed that there was an increase (10-17%) in the light intensity hollow rod samples compared to rod samples.
