Halogen Bulb 12V HS1 with PX43t Base

This is a standard halogen headlight bulb widely used in motorcycles, scooters, ATVs (All-Terrain Vehicles), and other light vehicles.

Key Features and Specifications:

1. Model & Specifications:

   • HS1: This is the bulb's "optical type." It refers to a specific motorcycle bulb standard with a single filament (typically used for the low beam). The filament position and beam pattern are designed to meet specific regulations for motorcycle headlights.

   • 12V: Rated operating voltage, compatible with most motorcycle electrical systems.

   • Wattage: Typically 35W (the most common for HS1). This wattage balances lighting brightness and the load on the motorcycle's circuit and battery.

   • PX43t: This is the crucial base/bayonet type. It denotes a metal bayonet base with three locating pins (the "t" often stands for three pins/tabs). It locks in place by rotating, providing a secure, vibration-resistant connection ideal for motorcycles.

2. Application:

   • Primarily used for the low beam (dipped beam) on motorcycles. Many motorcycles use separate bulbs for low and high beams (e.g., an HS1 for low beam and an HS2 or H4 for high beam), or two HS1 bulbs (one for low, one for high).

   • Commonly found in various mid-to-low displacement street bikes, scooters, and off-road motorcycles from European, Japanese, and domestic manufacturers.

3. Advantages:

   • Direct Replacement: As a common OEM type, replacement is straightforward.

   • Excellent Vibration Resistance: The PX43t base design effectively withstands the vibrations experienced on motorcycles.

   • Cost-Effective: Halogen technology is mature and affordable.
