Sealed Beam LED Replacement Headlights for GMC C1500 2500 3500 Trucks (2 Pack)

Modernize your classic GM truck or vintage ride with sleek Black Projector LED Headlights – USA-designed sealed beam replacements that deliver sharper optics and brighter output than halogen or HID, fitting H4701/H4703 applications across dozens of '80s and '90s vehicles.

Ditch Those Dim Sealed Beams for Modern LED Performance

If you're driving a square-body Chevy, classic GMT400, or any of the dozens of '80s and '90s GM vehicles still rocking factory sealed beam headlights, you know the struggle. Those old-school halogens were adequate in 1988, but today's roads demand better visibility – especially if you're keeping your classic truck on the road as a daily driver or weekend warrior.

These Black Projector LED Headlights replace outdated H4701 and H4703 sealed beam units with cutting-edge LED technology and true projector optics. Designed in the USA specifically for rectangular sealed beam applications, they deliver a crisp cutoff beam pattern that puts light on the road without blinding oncoming traffic. Whether you're cruising your K5 Blazer, restoring a GMT400 Suburban, or keeping a Pontiac Sunbird running strong, this upgrade transforms nighttime driving from sketchy to confident.

Key Features at a Glance

• True Projector LED Design: Modern projector lens with precision cutoff beam eliminates the scattered, yellow glow of sealed beams for sharp, focused white light
• 45W LED Chipset: Advanced LED technology outperforms traditional sealed beams and even HID conversions in both brightness and beam quality
• Direct H4701/H4703 Replacement: Fits any vehicle using these common sealed beam part numbers – covers everything from square-body Chevys to classic Pontiacs
• Black Housing Design: Durable polycarbonate lens with black housing gives your classic ride a stealthy, modern appearance
• USA Engineering: Designed domestically with superior beam optics and highly efficient construction

Installation & Wiring Details

Installation is straightforward – these replace your sealed beam units directly in the existing headlight buckets. Note: Some vehicles like C1500 models may require minor Dremel work for perfect fitment. These use H7 plug connections; depending on your vehicle's original wiring, you may need an H7 female adapter (sold separately) or simple splicing to connect to your factory plug. Sold as a pair (2 lamps) for low beam positions – if upgrading high beams too, order 4 total.

Built for Longevity

Constructed with durable polycarbonate lenses and black aluminum housing, these LED headlights handle the vibration and temperature cycling that comes with vintage vehicle ownership. LED technology means significantly longer life than halogen sealed beams – no more bulb replacements every couple years.

Your Benefits at a Glance

• Instant Visual Update: Black projector housings modernize your classic's front end
• Dramatically Improved Visibility: See farther and clearer than factory sealed beams ever could
• Safer Night Driving: Precise beam cutoff prevents blinding other drivers while maximizing your road illumination
