Holley Holley RetroBright Headlight: Modern White (5x7" Rectangle) LFRB150 - LFRB150

The Holley RetroBright LED Headlight in Modern White (5×7" Rectangle) — SKU LFRB150 is a plug-and-play LED upgrade engineered for classic and vintage vehicles that use the standard 5×7-inch rectangular headlight format. With a crisp 5700K Modern White output, this headlight delivers the clean, contemporary light quality enthusiasts want while preserving the retro proportions and styling cues that keep a build period-correct. Whether you're cruising the boulevard, carving backroads, or lighting up a trail run, the RetroBright LFRB150 is built to outperform the old sealed-beam it replaces.

Key Features & Benefits

• 5700K Modern White Color Temperature: The LFRB150 produces a bright, cool-white light output at 5700K — the same crisp hue you see on modern factory LED vehicles — giving classic builds a contemporary feel without altering their silhouette.
• Direct Plug & Play Installation: Designed to plug directly into the factory headlight harness, so there's no rewiring, no adapters to source, and no cutting into your original wiring. This dramatically reduces install time and keeps the build reversible.
• LED Technology vs. Sealed Beam: LED headlights offer better forward visibility, significantly reduced power draw on your vehicle's electrical system, and a longer service life compared to traditional sealed-beam headlights — real advantages on any aging platform.
• Retro-Correct Styling: The RetroBright line is specifically designed to maintain the classic headlight appearance. The 5×7" rectangular form factor blends seamlessly into factory housings, so your build looks right from the outside while the technology inside is thoroughly modern.
• Multiple Color Temperature Options in the RetroBright Family: The LFRB150 is the Modern White variant. If you prefer a warmer glow, Holley also offers a Classic White (3000K) version in the same size — useful context when choosing which tone suits your build's aesthetic.
• Trusted Holley Engineering: Holley is a well-established name in the performance and hot rod aftermarket, and the RetroBright line was purpose-built for enthusiast applications — not a generic retrofit kit.

Fitment

The Holley RetroBright LFRB150 is designed to fit any vehicle that originally used a standard 5×7-inch rectangular sealed-beam headlight — a format found on a wide range of classic American muscle cars, hot rods, trucks, and vintage imports. Common applications include many Fox-body Fords, classic GM trucks and intermediates, and other domestics from the 1970s–1990s that relied on this sealed-beam size. Because fitment depends on your vehicle's headlight bucket size rather than make/model/year alone, we strongly recommend verifying your existing headlight dimensions before ordering. Holley also offers RetroBright headlights in 5.75" round, 7" round, and 4×6" rectangular sizes for other applications — make sure you're ordering the correct format for your build.

Frequently Asked Questions

Does the LFRB150 require any wiring modifications?

No. The Holley RetroBright LFRB150 is a plug-and-play design that connects directly to your vehicle's existing factory headlight harness. No cutting, splicing, or additional adapters are needed.

What's the difference between "Modern White" and "Classic White" in the RetroBright lineup?

Both are LED headlights in the same 5×7" rectangular format. The LFRB150 (Modern White) uses a 5700K bulb for a bright, crisp, cool-white light — similar to contemporary factory LED headlights. The Classic White variant uses a 3000K bulb for a warmer, more golden hue that some builders prefer for an era-correct look. The choice comes down to the visual aesthetic you want for your build.

How do I know if this headlight fits my vehicle?

The LFRB150 fits vehicles that use a standard 5×7" rectangular headlight. The most reliable way to confirm fitment is to measure your existing headlight or check your owner's manual for the headlight format.
