Holley's RetroBright LED Headlights enhance classic sealed beams with modern LED technology, offering better visibility, longer life (6 times that of halogen), and lower power consumption. Their low-profile design fits most shallow headlight buckets without modification. Developed in collaboration with Morimoto, these headlights feature a PWM LED driver to maintain peak brightness. The 7" Round model provides 32,000 Candela for low beam and 53,000 Candela for high beam—three times brighter than original headlights.RetroBright lights are available in 5.75" round, 7" round, 4"x6" rectangular, and 5"x7" rectangular sizes, with color temperatures of 3000K for a classic look or 5700K for a brighter, modern appearance. European-style yellow lenses are also offered. They replace Sealed Beam Trade Numbers: H5054, H6052, H6054, and are sold individually—order 2 for dual or 4 for quad headlight setups. Note: Some applications, especially early 90s Toyota models, may need a separate harness for wiring adjustments, such as the H840 switched ground harness.
