IHNZCB 7x6 inch H6054 Glass Square Headlight Kit with H4/9003 High-Low Bulbs — Pair, OEM-Style Halogen Conversion

IHNZCB 7x6 inch H6054 glass square headlight housing paired with H4/9003 high-low beam bulbs is a plug-and-play conversion kit that restores the classic OEM glass headlight look while delivering reliable halogen dual-beam performance.

This assembled pair kit includes two 7x6 inch H6054 glass housings with two wire harnesses and two H4/9003 high-low beam bulbs, designed as a like-for-like replacement for vehicles originally equipped with square glass headlights. The kit keeps the original sealed-halogen appearance but upgrades worn or damaged units with fresh glass, a durable plastic rear shell, and high-output H4/9003 bulbs to improve nighttime visibility without altering the vehicle’s stock styling.

Will these housings fit my vehicle’s existing headlight buckets?

These housings are built to the original 1:1 dimensions of typical H6054 7x6 inch square units, making them compatible with many trucks, vans, and classic cars that used this OEM format. Most installs are plug-and-play; however, a small number of vehicles may require minor adjustments to the headlight bucket or tab slots.

• Fits vehicles using 7x6 inch H6054 sealed housings.
• Includes two wire harnesses for straightforward connection.
• Some models may need a tab slot filed or a small trim modification.
• Confirm your original housing model before purchase to ensure fit.

How bright and durable are these glass housings with H4/9003 bulbs?

The glass lens paired with the supplied H4/9003 halogen bulbs improves beam clarity and pattern compared with aged or cloudy sealed lights. The housings use a heat-resistant plastic rear shell and vibration-resistant construction for extended service life in road conditions.

• Glass lens resists yellowing and preserves beam definition.
• H4/9003 bulbs provide standard high and low beam functionality.
• High-temperature flame-retardant plastic back resists heat and impact.
• Built to withstand vibrations and temperature swings for longevity.

What installation steps or tips should I know before fitting them?

Installation is typically simple: remove the old sealed unit, connect the harnesses, seat the new housing, and secure it into the bucket. If a tab or mount point prevents seating, a small amount of filing or trimming on the bucket or tab may be required to achieve a flush fit.

• Turn off power and remove the battery ground if needed for safety.
• Compare the new housing dimensions to your original before starting.
• Plug in the included harnesses and test high/low functions prior to final mounting.
• File or grind a small tab only if the housing will not seat otherwise.

Will upgrading to these change my vehicle’s appearance or wiring?

The kit preserves the classic sealed-glass headlight aesthetic so the outward appearance remains OEM-style while replacing worn components. Wiring changes are minimal because the H4/9003 bulbs follow standard halogen connections; supplied harnesses simplify compatibility with most factory sockets.

• Maintains original glass headlight look and sizing (1:1 design).
• Uses standard H4/9003 bulb wiring for high/low beam operation.
• No major rewiring for most vehicles — simple plug-in harnesses included.
• Designed as a direct replacement to preserve factory aesthetics.
