Diode Dynamics HP11 LED Bulbs

The Diode Dynamics HP11 LED Bulbs are designed for customers who want a simple LED upgrade for compatible factory incandescent bulb locations. These bulbs add a brighter, cleaner LED appearance while retaining a socket-based replacement format for supported turn signal, tail light, reverse light, marker light, and exterior lighting applications.

Each HP11 bulb is rated at 310 lumens per bulb, giving customers a measurable output upgrade for compatible applications. Diode Dynamics emphasizes measured lumen ratings rather than estimated output, helping customers compare real performance more accurately.

The HP11 design uses four COB-style side-firing LED chips and a single high-power top-mounted chip with a projector lens on select configurations. This layout helps spread light through the factory lens while also directing output forward for stronger visibility in the intended lamp location.

Built for long-term reliability, HP11 bulbs feature full metal heatsinking, constant-current circuitry, and transient suppression. These features help manage heat, maintain stable LED performance, and reduce the flickering or early failure issues sometimes found with lower-quality replacement bulbs.

Socket and electrical design vary by application. Diode Dynamics lists 7440/7443 HP11 bulbs with a nonpolar and CK-compatible electrical design, while broader HP11 availability includes 1156, 1157, 3157, and 7443-style bulbs in colors such as Amber, Red, and Cool White depending on part number and pack quantity.

Whether customers are upgrading turn signals, tail lights, reverse lights, marker lights, or other compatible factory bulb locations, Diode Dynamics HP11 LED Bulbs deliver an easy plug-in LED replacement with improved output, cleaner styling, and dependable construction. Now Available at LEER!
