How do the different bulb types differ in our courses?
We teach H7, H11, 9005, 9006, 9012, LED, HID and projector bulb systems. You learn how filament design, base type, wattage and beam pattern affect light output and legal compliance.

All required specialty tools are provided with the premium course package. The core curriculum includes step-by-step instruction on proper tool usage and safe handling of every bulb type.
When should I consult a certified technician instead?
We always recommend professional service when dealing with CAN-bus systems, adaptive headlights, vehicle warranty concerns or if the dashboard shows bulb error codes after replacement.
How does beam verification work in the courses?
Each module ends with a guided beam alignment checklist using a wall test pattern and smartphone app that measures cut-off height and spread before any final road test.
