For positive ground or negative ground. 5 to 30 Volt wide voltage. Long life up to 30,000 hours. Made with CREE 2525 LED's for long life. Dual filament up to 1200 Lumen low beam. Works both in a socket that is wired for a single filament and works in a ba15d socket that is wired for dual filament. Up to 1800 Lumen high beam. The base is BA15D the diameter is 15mm with two contacts on the bottom and parallel bayonets. Made with aviation aircraft aluminium to keep the leds cool for longer life. Dimensions are overall length is 2.52 inches. The width is 0.98 inches. The length of the body above the BA15D base is 1.77 inches. The circuit board is super conducting aluminum for maximum power supplied the the leds. The led headlamp is a constant current device so the brightness will not fluctuate. CE and Rohs listed. Made with leds on both sides so for low beam only one row on both sides is illuminated for high beam both rows of leds light up on both sides. The reason the leds light up on both sides of the led headlight is to simulate the original filament by splitting the led into to sides. The reason the led has to be split up on both sides is because the led light CSP only can light up to 120 degrees. Since to emulate the original filament two 120 degree CSP leds have to be used to properly reflect light of the headlight fixture. Available in White 6500K. Upgrades the 32/50 CP bulb to 94/141 CP incredibly bright led headlight. Please do not look directly at a lit led. Made with CSP leds for optimum led/filament alignment. LED headlamps work with a generator or an alternator. Since this led is rated from 5 to 30 volts, this bulb works great in 8 volt Fords. This bulb works excellent in the 6 volt positive ground or negative ground Fords. Since led lighting uses less than 80% energy your generator or alternator is very happy to drive led headlights. Uses 800mA for low beam and 1.4A for high beam. This bulb will work in 6V, 8V, 12V, 24V up to 30V systems positive ground or negative ground. Easy to install just remove the old incandescent bulb and insert the new led headlamp. Since the led bulb is solid state you do not have to worry about broken glass or broken filament. This DIY job is fast less than a hour minute usually. Since there are no modification to the vehicle, truck, tractor or motorcycle. This headlight works either ac or dc. The LED wattage is 5 Watts comparable to a 35 to 45 Watt incandescent bulb. This bulb works perfect for 8 volt Model T's since it voltage range is from 5 to 30 volts. How to install a led light to replace a halogen with led technology? First make sure power is off to the headlights. Push down and twist counter clockwise until bayonets unlock then remove. Please insert the new led headlight by pushing down and twisting clockwise to seat the bayonets in the female socket. The socket is 15mm diameter with two contacts on the bottom. It is called the BA15D the "BA15" means bayonet with 15mm and the D means double for two contacts on the bottom. The headlight beam can be changed by rotating the headlight by 180 degrees if your low beam on the steering wheel and the headlight output high beam. The led row furthest away from the base works better as the high beam. Please check the headlight to make sure both leds are illuminating when the high beam is selected. Just one row of leds on both sides light when low beam is selected. The lights are really bright using the latest CSP leds. Chip Scale LED is the latest led technology for led headlights. The CSP led chips are close in size to a filament in a halogen or incandescent bulb. Since the CSP is close in size to the original filament you are getting the best designed led headlight for vintage or classic cars, trucks or motorcycles. Please be careful when adjusting the headlight fixture not to adjust to far inward or too far outward. After installing the leds you will hear the difference your generator or alternator noises since the equipment provides 90% less energy for the headlights to light. Works with both positive ground or negative 5 to 30 volts. Can be used as a very bright tail lights or or very bright brake lights. When the led lamp is tested we test for positive ground by applying - 6 volts to the contact. Either contact we will light depending if we want to test low beam or high beam. The base is connected to ground. We can test the other way too by connecting the plus 6 volt led to the contact and the ground to the side of the led headlight. The CREE CSP 2525 SMD leds are the best leds to simulate the filament of a light bulb. The 2525 means the smd chip outline is 25mm by 25mm which is perfect size for a surface mount led. The led headlight is not dim-able since it is a wide voltage device from 5 to 30 volts AC or DC. Since the led headlamp operates all the way down to 5 volts helps out staying light for the older Fords that are 6 volt. Since the CREE CSP leds are surrounded by aluminum they will last a very long time. Please see warranty details at the bottom of the product detail page. These bulbs will work in all older vehicles, scooters that were built before World War II. Most vehicles built before World War II were 6 volt positive ground or negative ground chassis. Since the led headlights last a long time and have a slow decay rate the lights should last a lifetime for the vehicle.
