Holley Holley RetroBright Headlight: Euro Yellow (7" Round) LFRB115

The Holley RetroBright LED Headlight in Euro Yellow (7" Round) — LFRB115 is a modern-tech LED upgrade designed for classic vehicles originally equipped with 7-inch round sealed beam headlights. Whether you're cruising boulevards, carving backroads, or pushing your classic down a trail after dark, this Holley performance lighting upgrade delivers dramatically improved visibility while preserving the period-correct look your build deserves.

Key Features & Benefits

• Euro Yellow Lens — Classic Aesthetic, Modern Output: The distinctive Euro Yellow lens delivers a period-correct, retro-styled appearance that's right at home on vintage builds, while the LED internals provide far more output than the original sealed beam it replaces.
• Massive Candela Output — Nearly 3× More Light: According to manufacturer data, the RetroBright 7" Round produces 32,000 candela on low beam and 53,000 candela on high beam — nearly three times the light output of a traditional sealed beam headlight. That's a real-world safety upgrade, not just a style change.
• Modern LED Technology in a Sealed Beam Form Factor: Holley engineered this light to drop directly into the same 7-inch round housing your classic car already uses, so you get the longevity, efficiency, and brightness of LED without modifying your grille or headlight buckets.
• Plug & Play Installation: The LFRB115 plugs directly into your factory headlight harness, eliminating the need for custom wiring or relay kits in most applications. This makes it one of the most accessible headlight upgrades available for sealed-beam classics.
• Forward-Facing LED Design: Holley's forward-facing LED layout is engineered to maximize light projection down the road, not just light up the lens itself — a key differentiator from some budget LED conversion options.
• Trusted Holley Performance Engineering: Holley is one of the most recognized names in American performance, with decades of experience engineering parts for classic and modern muscle vehicles alike. The RetroBright line reflects that same commitment to quality and fitment accuracy.

Frequently Asked Questions

Q: Will the LFRB115 plug into my factory wiring without modification?
A: Yes — the RetroBright LFRB115 is designed as a plug-and-play replacement that connects directly to the factory headlight harness, making installation straightforward for most classic car applications without custom wiring.

Q: Is this the same as a standard white LED headlight? What makes Euro Yellow different?
A: The Euro Yellow lens gives this headlight its distinctive vintage appearance, providing a period-correct look associated with classic European and American motorsport styling. If you prefer a modern white output, Holley offers the RetroBright in other lens color options — contact us for availability.

Q: How much brighter is this compared to my original sealed beam?
A: According to Holley's published specifications, the RetroBright produces 32,000 CD on low beam and 53,000 CD on high beam — nearly three times the output of a traditional sealed beam headlight.

Q: Does this fit both headlight positions on a four-headlight setup?
A: The LFRB115 is a 7" round forward-facing light. If your vehicle runs a dual 7" round setup (one per side), you would need two units. If your vehicle uses a four-headlight configuration with different-sized inboard/outboard lamps, verify sizing before ordering. Our fitment team can help — reach out at 813-535-5801.
