Diode Dynamics HD LED Semi-Flex Strip Lighting

The Diode Dynamics HD LED Semi-Flex Strip line represents the highest standard in USA-engineered automotive accent lighting. Built on Diode Dynamics' proprietary HDHalo Technology, these strips are purpose-built to deliver maximum brightness and perfectly uniform output for headlight, taillight, DRL, turn signal, and general accent lighting applications across automotive, motorcycle, marine, RV, and powersports platforms.

Each strip is densely populated with high-output, high-density LEDs and finished with a proprietary diffusing gel coating that eliminates hot spots and individual chip shadows — producing a seamless, solid glow when illuminated. When off, the gel conceals the LED chips entirely for a clean, OEM-quality appearance that integrates naturally into sealed lamp housings and custom builds alike.

Key Features:

• HDHalo Technology — high-density LED platform engineered for maximum brightness and uniform output, visible even in direct sunlight
• Proprietary diffusing gel coating — creates a seamless, solid glow with no visible hot spots or chip shadows; conceals LEDs when off for an OEM-quality appearance
• Multi-function PWM drivers — fully waterproof drivers support low-power, high-power, and turn signal operating modes with no external controllers required
• Semi-flexible construction — conforms to curved and complex mounting surfaces for versatile installation inside sealed lamp housings and custom applications
• Integrated mounting tabs — enable secure custom positioning using adhesive or beading wire; tabs can be trimmed if needed
• Field-trimmable design — strips can be shortened by up to 20% using side-cutting snips while remaining fully functional
• Assembled in the USA — designed, tested, and manufactured domestically in St. Louis for rigorous quality control and rapid integration of the latest LED technology
• Tested to SAE and DOT standards — photometric and environmental compliance ensures long-term reliability in demanding automotive environments
• Transient voltage suppression — built-in protection features safeguard performance across a wide range of automotive electrical systems

The HD LED Semi-Flex Strip line is available in multiple configurations suited for a broad range of lighting functions — from white DRL and switchback turn signal applications to single-color accent and signal lighting in a variety of colors. Every strip in this product family is backed by Diode Dynamics' industry-leading 3-Year Worry-Free Warranty, providing fast replacement with no return-and-repair delays.
