Bulbs

Automotive bulbs are essential components of a vehicle's lighting system, providing illumination for visibility and signaling. These bulbs are used in various locations, including headlights (low and high beam), turn signals, brake lights, and interior lighting. Bulb technology ranges from traditional halogen to long-lasting LED and xenon/HID options, each offering different brightness, color temperature, and energy efficiency characteristics. Selecting the correct bulb type and wattage is critical for safe operation and compliance with vehicle regulations.
