Specifications

The HD40040W Round Backup Light blends performance and durability for demanding vehicle lighting applications. It features 40 high-output 5 mm white LEDs beneath a clear convex dot lens, engineered for superior light projection. Built for 7.5–14 VDC systems, this lamp draws a modest 280 mA while delivering exceptional visibility when backing. The fully sealed polycarbonate lens and housing resist moisture and corrosion, while the conformally coated circuit board ensures longevity. A standard PL-3 connector allows for seamless replacement or retrofitting. Compact and rugged, the HD40040W offers long life — up to 100,000 hours — and pairs with optional accessories like grommets, chrome covers, flanges, and connectors to fit any build. Ideal for trucks, trailers, and commercial fleet service.
