The Holley RetroBright 4x6 Rectangular LED sealed beams produce 18,000CD for low beam, and 37,000CD for high beam, which is nearly three times more light output than your original lights. Their beam pattern is well distributed for excellent width, long-range visibility, and added range in high beam mode. These patent pending lights were engineered entirely in the USA by Morimoto, the masters in performance automotive lighting. Will fit all 1977-81 Firebirds with no modifications to the buckets or wiring. We include adapters that have been repined which makes these a plug and play installation. When your high beams are on you will have all 4 lights on at once. Features a modern white output rated at 5700k. Though the rated lifespan of each LED headlight is over 20,000 hours, the Holley RetroBright is designed to be serviceable. If a light ever goes out, the proprietary LED cartridge can be unbolted and replaced with a new one. The heart of the headlight is powered with high quality LEDs from Philips-Lumileds. These aren't cheap emitters to begin with. Your classic car has already withstood the test of time and the UV-coated polycarbonate lens will take another couple decades worth of abuse without fading. You can feel the precision in the heavy-duty die-cast housings that double as a heat-sink. A special PWM LED driver resides inside of the headlight to keep the LED's running at their peak intensity, even during prolonged periods of use. There is no cutting, repin or splicing required. You will not need in-line resistors or any other modifications.
Product includes: a pair of headlights (low or high beam only, you will need a quantity of 2 for all 4 lights)
