Product Specifications

This PSY24W halogen lamp is equipped with a PG20/4 (PG20-4) standard base, serving as a dedicated light source for 12V low-voltage automotive signal lighting scenarios. It offers excellent compatibility and stable installation, with the industry universal model number 12180. It is widely used in automotive turn signals, amber daytime running lights, side marker lights, auxiliary signal lights and small warning lights, complying with ECE R37, SAE/DOT and other specifications to meet road use requirements.

Rated at 12 volts and 24 watts, it uses tungsten filament illumination combined with halogen cycle technology to emit about 300 lumens of amber light (some versions have a silver coating that emits compliant amber light when lit). With a color temperature of approximately 3125K and natural color rendering (CRI ≥ 80), it can clearly transmit signals and improve vehicle recognition. The lamp body is made of quartz glass with a UV filter and has a compact structure (approximately 48mm in length). It features instant lighting, shock resistance, insulation, voltage fluctuation resistance and other characteristics. The standard B3 lifespan is about 500 hours, which can reach 1000 hours under proper usage. Balancing the clarity, reliability and cost-effectiveness of signal transmission, it is a high-quality original equipment replacement option for automotive signal lighting.
