Holley Holley RetroBright Headlight: Classic White (5.75" Round) LFRB125

The Holley RetroBright LED Headlight (LFRB125) is a 5.75-inch round LED sealed beam replacement designed to bring modern lighting technology to classic vehicles. Finished in a warm 3000K Classic White color temperature, this hi/low beam unit delivers a period-correct look with the visibility and longevity advantages of LED technology — making it one of the most popular sealed beam upgrades for muscle cars, classic trucks, and vintage builds.

Key Features & Benefits

• LED Technology in a Sealed Beam Form Factor: The RetroBright drops directly into any application that accepts a 5.75-inch round sealed beam headlight, so you get a meaningful modern upgrade without cutting or modifying your classic vehicle's headlight buckets.
• 3000K Classic White Color Temperature: The warm Classic White output is intentionally tuned to complement the aesthetic of vintage and retro builds — it avoids the stark blue-white look of higher Kelvin LEDs while still outperforming old-school halogen sealed beams in clarity and efficiency.
• Hi/Low Beam in One Unit: The LFRB125 includes both high and low beam functions, so a single bulb handles your full headlight needs — no need to source separate hi and lo units for a standard sealed beam application.
• Modern-Tech Upgrade for Old-School Systems: Described across multiple sources as a "modern-tech upgrade for old-school sealed beam headlight systems," the RetroBright line is purpose-built for classic car restorers and builders who want reliability and performance without sacrificing originality of appearance.
• Trusted Holley Brand: Holley is a well-established name in performance and restoration parts, and the RetroBright line is a dedicated product series — not a rebadged generic — giving buyers confidence in quality control and parts support.
• Sold Individually: The LFRB125 is sold as a single headlight unit, giving you the flexibility to replace one at a time or purchase multiples as your build requires.

Fitment

The Holley RetroBright LFRB125 is designed to fit any vehicle that uses a 5.75-inch round sealed beam headlight. This is an extremely common size across a wide range of American classic cars, muscle cars, vintage trucks, and early imports from the 1950s through the 1980s and beyond. If your vehicle currently runs a standard 5.75" round sealed beam, the RetroBright is a direct-fit upgrade.

Because fitment depends on your existing sealed beam size and housing type rather than a specific year/make/model list, we strongly recommend verifying your current headlight diameter before ordering. Our team at ThreePiece.us can help confirm fit — reach out via the fitment help link on this page or call us directly. Note that the LFRB126 is a related unit in the RetroBright lineup; confirm the correct part number for your specific application before purchasing.

Frequently Asked Questions

Q: Is this headlight a direct replacement for my existing 5.75" sealed beam?
A: Yes — the Holley RetroBright LFRB125 is specifically designed as a modern LED upgrade for standard 5.75-inch round sealed beam headlight systems. It is intended to fit in place of your existing sealed beam without modification to the housing or bucket.

Q: Does this unit include both high and low beam, or do I need to buy separate bulbs?
A: The LFRB125 is a hi/low combined unit, meaning it handles both high and low beam functions in a single headlight. You do not need to purchase a separate high beam bulb for a standard sealed beam application.

Q: Is the LFRB125 sold as a pair or individually?
A: It is sold individually — as a single headlight unit. If your vehicle requires two 5.75" round headlights (one per side), you will need to purchase two units.

Q: What is the difference between the LFRB125 and the LFRB126?
A: Both are 5.75-inch round RetroBright LED headlights in Classic White (3000K), but the LFRB126 is listed separately in the Holley lineup. The LFRB125 is the hi/low beam unit. We recommend contacting our fitment team to confirm which part number is correct for your specific vehicle and headlight configuration before ordering.
