Rebaydo 1pc P15D-30 LED Headlight 8 Volt 60 SMD Dual Filament is designed for classic and vintage vehicles including Ford applications and works on either positive or negative ground systems. It uses 60 SMD LED technology with 60 individual emitters for improved light output and efficiency. The unit is CE and RoHS compliant and is tested before shipping for quality assurance. This LED headlight produces up to 900 lumens on high beam and up to 600 lumens on low beam and is dimmable when used with a variable voltage supply. It operates within 6.53V to 9.47V with a maximum voltage rating of 10V. A voltage regulator is required in vintage vehicle headlight circuits to prevent damage from over-voltage conditions. The base features a 15mm diameter with a 30mm retaining ring and is designed for P15D-30 sockets. Contact alignment should be verified prior to installation as some 2320-style applications may have rotated contacts. At 8 volts, current draw is approximately .100A on low beam and .350A on high beam. The LED design is optically aligned for improved beam efficiency and reduced load on the electrical system. Dimensions include a maximum overall length of 1.95 inches and a maximum diameter of 1.0 inch for compact fitment in vintage housings. This product is non-cancelable, non-returnable, and non-warranty (NCNRNW), and each unit is individually tested before shipment.
