Grote 66905 6” Sentry Light Pigtail – 16-Gauge Three-Wire Chassis Ground with .180 Male Bullets

Heavy-Duty 16-Gauge Connectivity for Sentry Series Lamps

The Grote 66905 is a high-performance 6-inch three-wire pigtail specifically designed for the Grote Sentry lighting series. Built with thicker 16-gauge GPT wire, this pigtail provides superior electrical conductivity and physical durability for 5206-, 5202-, and 5306- series lamps. It is the ideal choice for heavy-duty applications requiring a robust, vibration-resistant connection.

Ultra-Blue-Seal® Corrosion Defense

Protect your vehicle's electrical system from the leading cause of failure: moisture. The 66905 is engineered with Grote’s Ultra-Blue-Seal® technology, featuring factory-molded plugs and an integrated O-ring. This "Sealed Plug-In" design creates a weather-tight barrier that stops water wicking and road salt from reaching the terminals, ensuring your marker and turn signal lamps stay bright and operational in any weather.

Versatile Chassis Ground Configuration

Designed for straightforward installation, the 66905 features a Chassis Ground setup. One lead is terminated with a secure ring terminal (eyelet) for direct frame grounding, while the other two leads use Slim-Line .180" male bullet connectors for power and signal. This configuration allows for a clean, efficient "plug-and-play" setup that reduces installation time and simplifies maintenance.
