How can you diagnose a burned-out bulb in the Toyota Hilux?

Visual Inspection: Look for a broken filament o r blackened glass inside the bulb.
Bulb Swap Test: Replace the suspected bulb with a working one to check.
Use a Multimeter: Measure continuity across the bulb’s terminals. If there’s no reading, the bulb is dead.
Check for Power at the Socket: If the bulb is good but doesn’t light up, the issue might be in the wiring o r fuse.
