Holley Holley RetroBright Headlight: Classic White (7" Round) LFRB135

The Holley RetroBright LED Headlight in Classic White (LFRB135) is a 7-inch round LED headlight designed as a direct-fit upgrade for classic cars, trucks, and off-road vehicles that use the standard 7" round headlight format. Holley Performance has engineered the RetroBright line to give your vintage ride the look of a period-correct sealed-beam headlight while delivering the modern output and longevity of LED technology. Whether you're cruising the boulevard, navigating a dark backroad, or finishing off a restomod build, the LFRB135 is a plug-and-play solution that fits right into your existing headlight bucket.

Key Features & Benefits

• 3000K Classic White Color Temperature: The warm 3000K output delivers a classic, vintage-inspired white light that complements period-correct restorations and restomod builds — no harsh blue tint, just a clean warm hue that looks right at home on a classic vehicle.
• Plug & Play Installation: The RetroBright plugs directly into your factory headlight harness, eliminating the need for rewiring, adapters, or custom fabrication. This makes the swap accessible even for home builders with basic tools.
• Low-Profile Housing Design: The housing is designed to fit most shallow headlight buckets found on classic cars without the need for cutting or drilling, preserving your vehicle's original structure.
• LED Efficiency & Longevity: As an LED unit, the RetroBright consumes less power, generates far less heat, and takes up less space than traditional sealed-beam halogen headlights — reducing the load on your classic vehicle's electrical system.
• Retro Styling, Modern Performance: The classic round styling maintains period-correct appearance, making it ideal for show cars, street machines, and daily-driven classics where authenticity matters.
• Holley Performance Engineering: Backed by Holley's decades of experience in performance automotive components, the RetroBright line is built to the standards enthusiasts expect from the Holley brand.

Frequently Asked Questions

Q: Will the LFRB135 bolt directly into my classic car's headlight bucket?
A: Yes — the RetroBright features a low-profile housing designed to fit most shallow headlight buckets found on classic cars without cutting or drilling. As long as your vehicle uses a 7-inch round headlight opening, it should drop right in.

Q: Do I need to rewire anything for this headlight to work?
A: No. The Holley RetroBright is designed as a plug-and-play upgrade that connects directly to your factory headlight harness. No special wiring adapters or relays are required in most applications, though it's always good practice to verify your harness connector type beforehand.

Q: What's the difference between the Classic White (3000K) and Modern White (5700K) versions?
A: The 3000K Classic White (this unit, LFRB135) produces a warmer white light that closely resembles the look of traditional halogen headlights — ideal for period-correct builds. The 5700K Modern White produces a cooler, brighter-looking white that suits restomods or builds going for a more contemporary appearance.

Q: Is this a single headlight or a pair?
A: Based on available product listings, the LFRB135 is sold as a single headlight unit. If your vehicle requires two 7" round headlights (one per side), you will need to purchase two units.
