Switch Kit

The Streamlight Switch Kit is a precision upgrade component designed for users who own original Stinger LED flashlights and want to leverage modern C4 LED technology. This retrofit assembly transforms aging tactical lighting systems into high-performance illumination tools, making it ideal for law enforcement, security professionals, and serious outdoor enthusiasts who depend on reliable flashlight performance. By upgrading to the C4 LED platform, operators gain a significant brightness boost without replacing their entire flashlight, extending equipment lifespan while modernizing capability.

The Switch Kit includes both the advanced C4 LED module and the complete switch assembly required for seamless installation into compatible Stinger models. The C4 LED upgrade doubles output to 350 lumens—a meaningful increase that improves target identification, search capability, and tactical situational awareness in low-light environments. The integrated switch assembly ensures ergonomic activation and reliable tactile feedback, while the compact form factor (8.95 x 1.7 x 4.95 inches, weighing just 0.06 lbs) maintains the original flashlight's balanced handling characteristics. This modular design approach allows field users to maintain equipment familiarity while accessing next-generation LED efficiency and brightness.

This upgrade kit applies exclusively to original Stinger LED models that lack a "C" or "C4" designation in the serial number—verifying compatibility before purchase prevents installation errors. Professional users in patrol, tactical response, and security operations benefit most from this cost-effective modernization, as it preserves muscle memory with existing equipment while delivering measurable performance gains. Installation is straightforward for users familiar with flashlight maintenance, and the upgrade delivers immediate, noticeable improvements in beam intensity and coverage for search, inspection, and threat assessment tasks.
