Rebaydo 2 pcs 1158 LED Miniature Bulbs feature a BA15D 15mm bayonet base with even-height bayonets and two bottom contacts, designed for approx. 12V vehicle systems. This dual filament LED bulb provides separate low beam and high beam circuits, making it suitable for tail light, brake light, indicator, and other dual brightness miniature bulb applications. Built with 30 high output 5730 LEDs aligned for maximum reflector efficiency, it produces up to approx. 500 lumens on low beam and up to approx. 650 lumens on high beam. The compact design is smaller than the original incandescent bulb to help minimize installation issues in tight housings. Non-polarity construction allows operation in both positive ground and negative ground cars, trucks, motorcycles, and vintage vehicles. Long service life is rated up to approx. 30,000 hours. This bulb is dimmable when used with a variable voltage supply such as a dashboard dimmer. Maximum overall length is approx. 1.962 inches with approx. 0.741 inch diameter. Power consumption is up to approx. 4.5 watts on low beam and up to approx. 6 watts on high beam. Current draw at approx. 13.8V is as follows: White approx. 0.13A / 0.51A, Warm White approx. 0.13A / 0.54A, Yellow approx. 0.13A / 0.51A, Red approx. 0.09A / 0.33A, Blue approx. 0.08A / 0.53A, and Green approx. 0.09A / 0.55A.
