Partsam LED Headlight Assembly for 1988–1998 OBS Silverado/C/K Trucks — 6500K, DOT-Approved, Sequential DRL Turn Signal

These Partsam LED headlight assemblies are a direct-fit DOT-approved replacement for 1988–1998 OBS Silverado/C/K trucks, offering 6500K high-intensity LEDs, start-up animation, sequential DRL turn signals, and plug-and-play installation.

Upgrade your classic OBS truck lighting with a modern LED assembly designed to match original mounting points while delivering brighter, whiter illumination and eye-catching signal effects. The set replaces both high and low beams, integrates daytime running lights (DRL) with start-up animation, and adds sequential turn signals. Built to IP67 waterproof rating and engineered with external resistors, these headlights avoid hyper-flash and tolerate harsh weather without modification to your vehicle’s wiring when installed correctly.

How do these headlights improve visibility and safety at night?

Partsam uses high-intensity LED chips at a 6500K color temperature to produce a crisp, white beam that penetrates darkness and improves contrast of road edges and signs. The optics are engineered to distribute light farther and wider than many halogen units, reducing dark spots while keeping a controlled beam pattern that minimizes glare for oncoming traffic.

• 6500K cool white LEDs for improved contrast and longer visibility range
• Optimized optics for focused high/low beam patterns
• DOT/SAE approval confirms legal road use and regulated beam cutoff

Will these headlights fit my OBS Silverado/C/K without modifications?

Yes—these assemblies are made as direct replacements for 1988–1998 OBS models and match factory mounting and plug locations for a true bolt-on swap. Most installations are plug-and-play; if a lamp does not power on, reversing the connector is a quick fix. For 1994–1998 C10/C/K trucks, extra side marker lamps are included where applicable.

• Direct-fit design for 88–98 Silverado/C/K and compatible OBS models
• Includes left/right headlight assemblies and turn signal lights
• Extra side markers provided for 1994–1998 C10/C/K 1500–3500 models

What electrical protections and features are built in?

Partsam assemblies include external resistors to prevent common issues like hyper-flashing and to keep operating temperatures managed for reliable lifespan. The lights meet DOT and SAE standards and are sealed to IP67 to resist water and dust. Multiple functions—start-up animation, DRL, high/low beam, and sequential turn signals—are integrated into a single unit for convenience and modern styling.

• External resistors reduce hyper-flash and heat buildup
• IP67 waterproof rating for wet and dusty conditions
• DOT/SAE certification for compliant on-road use

How do the sequential turn signals and start-up animation work?

The turn signals illuminate in a left-to-right sequence for clearer direction signaling and a contemporary look that stands out in traffic. The start-up animation briefly cycles the DRL elements when power is applied, adding a modern visual cue each time you start your truck. These features are built into the assembly and activate using standard vehicle signals—no extra modules required in most cases.

• Sequential amber turn signals enhance visibility to other drivers
• Start-up DRL animation provides a distinctive, modern look
• Integrated functions typically operate with stock wiring and signals

Who is this for: These Partsam LED headlight assemblies are for owners of OBS Chevy/GMC trucks (1988–1998) who want a legal, direct-fit lighting upgrade with modern LED performance and style. Ideal for restorers, daily drivers, and off-road enthusiasts who need reliable waterproofing, stronger illumination, and enhanced signaling without cutting or modifying original factory fittings. If you want improved nighttime visibility, contemporary turn-signal effects, and a plug-and-play swap that keeps your truck street-legal, this kit is built for you.
