Specifications

The Automann 571.LD40R39 is engineered to meet the demands of commercial truck and trailer lighting by delivering reliable stop/turn/tail (S/T/T) functionality in a durable 4-inch round LED format.

The bright red LED output improves visibility for braking, turning and tail-lighting events, while reducing maintenance thanks to energy-efficient operation and extended life. Compatible with 12-volt systems and engineered for a clean retrofit installation, the 571.LD40R39 is an ideal choice for fleet managers and owner-operators seeking quality and reliability.
