This study investigates the thermal behavior of H7 halogen headlamps through Computational Fluid Dynamics(CFD) analysis and experimental validation. Headlamp geometries were reconstructed via reverse engineering, and simulations incorporated conduction, convection, and radiation effects using the Discrete Ordinate (DO) model. Experiments were conducted using thermocouples and infrared thermography to validate the numerical predictions. The results showed good agreement, with average discrepancies of 3–5% confirming the reliability of the simulation framework. These results demonstrate that current thermo-fluid simulation can accurately capture complex thermal transport phenomena in headlamp assemblies. The proposed methodology is extendable to LED headlamps, providing a practical tool for aftermarket product design, replacement part evaluation, and optimization of next-generation automotive lighting systems.
