Partsam LED Headlight Assemblies for 1988–1998 Chevy/GMC OBS Trucks — 6500K, DOT-Approved, Sequential Turn Signals

Upgrade your classic Silverado, C/K or Sierra with modern LED performance while keeping the original mounting and wiring intact. These assemblies are built to fit OBS (old body style) trucks from 1988–1998 and come as a full set with left/right headlight housings and turn signal lamps. With a crisp 6500K color temperature, IP67 weather resistance, and plug-and-play installation, the lights improve nighttime visibility and give your truck a contemporary look without cutting or drilling.

How do these headlights improve visibility and street legality?

The Partsam assemblies use high-intensity LED chips and optics tuned for beam control, delivering a bright, neutral-white output at 6500K while meeting DOT/SAE requirements for road use. The housings are engineered for focused high and low beams so light puts illumination where you need it without excessive scatter.

• DOT and SAE approved for lawful on-road driving
• 6500K LEDs for crisp white light and longer perceived range
• Separate high/low beam optics for controlled patterning
• IP67 rating protects against water and dust

What features does the assembly include and how do they work?

These headlight units combine multiple lighting functions—start-up animation, daytime running lights (DRL), sequential turn signals and dedicated high/low beams—into a single retrofit assembly. The sequenced amber turn signal and animated DRL add modern style while the integrated resistors help prevent hyper-flash and overheating.

• Start-up animation and DRL for visual presence during ignition
• Sequential amber turn signals for clearer lane-change signaling
• External resistors included to stabilize flash rates and temperatures
• Plug-and-play connections; flip plug 180° if a circuit is reversed

How difficult is installation and what’s included in the package?

Installation is designed to be straightforward: these are direct replacements for the factory sealed-beam heads and require no body modifications. The kit ships with both left and right headlight assemblies, turn signal lamps, and a basic instruction sheet to guide you through the plug-and-play swap.

• Full set: two headlight assemblies (L & R) and two turn signal lamps (L & R)
• Direct-fit for OBS 88–98 Chevy/GMC truck models—no cutting or custom mounts
• Include installation instructions and external resistors to prevent hyper-flash
• Quick troubleshooting tip: reverse the plug if a lamp circuit doesn’t power

Will these lights hold up to weather and highway use?

The assemblies are built with durable housings and sealed optics rated IP67, so they resist rain, splashes and dust. Thermal management and the included resistors reduce heat stress on the LEDs for longer life under regular driving conditions.

• IP67-rated seals keep moisture and debris out
• High-quality LED chips and optics for sustained brightness
• External resistors help maintain stable operating temperatures
• Designed to meet DOT standards for highway use

Who is this for? These Partsam LED headlight assemblies are aimed at owners of OBS-generation Chevrolet and GMC trucks (1988–1998) who want a reliable, legal upgrade that preserves factory mounting while adding modern lighting effects and improved night visibility. They suit DIY installers and professional shops seeking a plug-and-play replacement that adds style and function without permanent vehicle modifications.
