IHNZCB H4/9003 LED Headlight Conversion Kit — 7" H6024 Glass Round Housings, High/Low Dual-Beam, Brighter White Light

IHNZCB H4/9003 LED Bulbs paired with 7" H6024 glass round housings give a direct plug-in upgrade that preserves your vehicle's classic sealed-halogen appearance while delivering a brighter, cleaner beam.

If you want to modernize night driving performance without changing the vintage look of glass headlights, this conversion kit bundles H4/9003 high/low dual-beam LED bulbs with 7" H6024 glass housings. The components are engineered to match original halogen dimensions so the exterior appearance stays stock, while the LEDs and improved glass lens pattern optimize beam projection and reduce yellowing over time. The set is aimed at drivers who need better nighttime visibility, dependable materials, and a near plug-and-play installation on compatible vehicles.

How much brighter are these LED bulbs compared with stock halogen lights?

The included H4/9003 LEDs are designed to produce higher lumen output and a whiter color temperature than traditional halogen filaments, improving contrast and target recognition at night. Combined with the H6024 glass lens, the beam pattern is clearer and more focused, reducing scatter and glare when aligned correctly.

• H4/9003 dual-beam LED design for high and low beam functions
• Glass H6024 lens improves pattern fidelity and resists yellowing
• Whiter light helps differentiate road signs and lane markings

Will the kit keep the original look of my vehicle’s round headlights?

Yes — the housings are made to 1:1 size with standard halogen sealed-beam dimensions so they sit like the factory units. That preserves the classic glass appearance from the front while upgrading internal light technology to LED.

• Exact-size 7" H6024 glass housings match vintage sealed-beam dimensions
• Exterior silhouette remains unchanged for authenticity
• Ideal for restorations or owners who prefer a factory look

How difficult is installation and what vehicle modifications might be needed?

Most vehicles accept these housings and bulbs as a plug-and-play swap using the removable bulb sockets, so installation is straightforward for DIYers with basic tools. A few models may require minor trimming or filing of a retention tab in the headlight bucket to clear the housing; the kit does not require cutting into vehicle wiring for most installations.

• Removable bulb sockets for easy retrofitting
• Generally plug-and-play on compatible vehicles
• Some vehicles need slight tab filing or minor bucket adjustments

Are these headlights durable and weather resistant?

The housings use a glass lens with a high-temperature flame-retardant plastic rear shell to tolerate heat and road conditions. The construction is intended to resist vibration and temperature variation so the assembly maintains performance over time.

• Glass lens resists UV yellowing and lens degradation
• Plastic back shell engineered for heat and impact resistance
• Built to withstand road vibration and variable temperatures
