Partsam LED Headlights for OBS Silverado/C/K 1988–1998 — Chrome 6500K, DOT-Approved with DRL & Sequential Turn Signal

These chrome Partsam LED headlight assemblies are engineered to update classic OBS C/K 1500–3500 and Sierra/Silverado trucks with modern brightness and signaling while matching original mounting points. With a crisp 6500K color temperature, IP67 waterproof rating and external resistors to prevent hyper-flash, they deliver a brighter white beam and reliable operation in wet or dusty conditions. The set ships complete with left/right heads and turn signals plus installation instructions so you can swap them into your truck without cutting or fabricating.

How will these headlights change visibility on the road?

The 6500K high-intensity LED chips produce a whiter, farther-reaching beam than many halogen originals, improving contrast and object recognition at night. Optic engineering focuses light where you need it without excessive scatter, while separate high and low beam elements maintain legal cutoffs for safe driving.

• Bright 6500K LEDs for clearer nighttime illumination
• Separate high/low beam optics for controlled light pattern
• DOT/SAE approval ensures on-road legality
• IP67 rating protects electronics from water and dust

What signaling features are included and how do they work?

These assemblies integrate daytime running lights (DRL), sequential turn signals, and a distinctive start-up animation that activates when the vehicle starts. The sequential turn signal provides a modern sweeping motion for clearer intent signaling, and external resistors eliminate rapid hyper-flash that some LED conversions experience.

• DRL for increased daytime visibility
• Sequential amber turn signals for attention-grabbing indication
• Start-up animation adds a factory-like welcome sequence
• External resistors pre-installed to stabilize flasher rate

Will these fit my OBS Silverado or Sierra without modification?

Yes — Partsam designed this kit as a direct replacement for many 1988–1998 Chevy and GMC C/K and Sierra/Silverado applications. The assemblies use stock mounting points and a plug-and-play wiring approach so installation is straightforward for owners comfortable with headlight swaps.

• Direct-fit for 1988–1998 OBS C/K 1500/2500/3500 and related Sierra/Silverado models
• No cutting or custom brackets required in most installations
• Includes left/right headlight assemblies and turn signal lights
• Flip the plug 180° if a lamp isn’t functioning, then reconnect

How durable and weather-resistant are these headlights?

The housings meet IP67 ingress protection standards, keeping moisture and dust away from internal electronics during adverse weather or off-road use. Robust LED chips and external resistors help maintain cooler operating temperatures and long-term reliability even with frequent use.

• IP67 waterproof rating for reliable wet-weather performance
• Heavy-duty chrome housings resist corrosion and UV fade
• External resistors reduce heat stress and hyper-flash risks
• DOT/SAE certification confirms tested road safety standards

Who is this for? These Partsam LED headlight assemblies are aimed at OBS truck owners who want a modern lighting upgrade without altering factory mounting or wiring. If you drive a 1988–1998 Chevy or GMC C/K, Sierra or Silverado and want brighter white light, sequential signaling, and plug-and-play installation with legal DOT approval, this full set is built to be a direct, durable replacement.
