Grote 66810 Two-Light 9" Y-Adapter Pigtail – Straight Female PL-3 to Male PL-3

Expand Your Lighting System with Ease

The Grote 66810 is a high-quality 9-inch Y-adapter pigtail designed to simplify the installation of multi-lamp configurations. Engineered specifically to accommodate 6-lamp systems, this adapter allows you to split a single power source to run two separate lights, making it an essential component for heavy-duty truck and trailer lighting upgrades.

Seamless Retrofitting and Protection

Built for versatility, the 66810 is designed for use with 4" round and oval Stop/Tail/Turn (S/T/T) lamps. It allows for easy retrofitting to superior Grote male pin LEDs and lamps without the need for extensive new wiring. To ensure long-term reliability on the road, the harness features molded terminations that effectively block out moisture and prevent corrosion buildup at critical connection points.
