The J.W. Speaker Model 8633 Evolution LED headlight is a powerful and compact upgrade for 5.75" (PAR46) pedestal mount sealed beam headlights, designed for superior performance, enhanced visibility, and rugged durability in demanding environments. Building on the foundation of the Model 8632 Evolution, the 8633 incorporates SmartHeat® Technology, offering an intelligent de-icing system that automatically activates based on external temperature conditions. This thermally conductive grid system melts ice and snow on the lens up to twice as fast as other solutions, ensuring reliable lighting even during harsh winter operation—all without requiring driver intervention.
The Model 8633 Evolution delivers bright, reliable light output that matches the performance of the Model 8630 and 8631 Evolution LED headlights. Its design integrates inner optics for high and low beams, while the outer ring provides turn signal, daytime running light (DRL), and front position lighting at high intensities for added visibility and safety. This combination of functions in a single unit makes it an excellent choice for modernizing 5.75” headlights across a wide variety of applications, from construction, industrial and mining vehicles to off-road 4x4s, specialty trucks, buses, and railroad vehicles.
Designed for efficiency and ease of use, the Model 8633 offers plug-and-play installation, and is available in both heated and non-heated versions. Heated variants come in single-light and two-light kit configurations, while non-heated versions are also offered as singles or kits. The light is available with DOT- and ECE-compliant options, making it fully road-legal in both North American and European markets.
With its innovative technology and durable construction, the Model 8633 Evolution LED headlight is engineered to meet the rigorous demands of work sites and off-road environments. Whether you're operating in cold climates, working around the clock, or upgrading your lighting system for reliability and performance, this headlight delivers outstanding value and versatility. Wire assembly is sold separately.
