Partsam LED Headlight Assembly for OBS Chevy/GMC 1988–1998 — 6500K Bright White, DOT-Approved DRL & Sequential Turn

These Partsam assemblies are designed as direct-fit upgrades for classic OBS Chevy and GMC trucks (1988–1998), combining modern LED optics with legal DOT/SAE approval. They deliver crisp 6500K white light for improved nighttime visibility, integrated daytime running lights and a startup animation for a contemporary look, plus sequential turn indicators that increase on-road communication. Built to IP67 standards and equipped with external resistors, they are intended to be plug-and-play replacements that minimize wiring changes and hyper-flash issues.

How do these LED headlights improve night driving for older OBS trucks?

The Partsam LEDs use high-intensity chips and optimized optics to project a brighter, whiter beam pattern than original halogen sealed beams, improving perceived contrast and reach without changing the original headlight housing. With a 6500K color temperature, they render road details more clearly while remaining DOT/SAE compliant for legal road use.

• 6500K cool white LEDs for sharper road illumination
• Optimized optics produce clearer cutoffs and longer throw
• DOT/SAE approved for highway legality
• IP67 rating resists water and dust in daily driving

What wiring or modifications are required for installation?

Installation is designed to be straightforward: these headlights are direct replacements for factory sealed-beam units and typically plug into existing connectors. External resistors are included to reduce hyper-flashing and keep operating temperatures lower, and most installations require no cutting or splicing.

• Plug-and-play fit for 1988–1998 Silverado/C/K OBS trucks
• External resistors included to prevent fast-blink turn signals
• Flip the plug 180° if any lamp orientation needs correction
• Extra side marker lamps provided for 1994–1998 C/K models when applicable

Are these headlights road-legal and durable enough for daily use?

Yes — the assemblies carry DOT/SAE approval, meaning they meet standard regulatory requirements for on-road lighting. The housings are engineered to be weather-resistant and the IP67 ingress protection rating helps keep moisture and debris out, extending service life under typical driving conditions.

• DOT/SAE approval ensures compliance with U.S. road standards
• IP67 waterproof rating for wet and dusty environments
• Robust LED chips and heat-managing design for longer life
• Resilient housings suitable for daily and seasonal use
