1 new SUPER Premier LED bulb for motorcycles and cars that use a British Pre-focus 12v dual filiments like Jaguar XK120, 140, 150, XK140, XK150 and up 22mm base with 36mm flange that use a prefocus 12v 50/40w bulb and others (See the pictures as a reference). It is a 12v-20volt dual function (high & low beam) DC bulb. It is non-polarity so there's no rewiring or modification needed to your machine. This bulb fits directly into your headlight and plugs into your harness. It is brighter, lasts longer, uses less watts (but is 10x brighter per watt), and will not melt your lens if kept on too long. It's also designed to all you to use the rear rubber dust cover and meet the OEM measurements for the prefocus. This bulb will last 50,000 hours (unless there's an electrical issue on the tractor).

This bulb is custom made with a front projection lens, the beam angle is 360 degrees, it has a steel base and an alloy body. However, it is the front projection lens that makes it so effective. It is about 2800lm in brightness. It's just a better engineered bulb. In the pictures there are illustrations of the bulb installed. The bulb will last 50,000 hours and is bright white in color (6500K).

See better and be better seen with BRIGHT-WHITER light.

Important: Please note that some late model machines might have came from the factory with AC power to the headlight. Even though the bike may have a battery in stock form, the headlight maybe AC powered. This LED bulb will smoke itself quickly on AC voltage. An AC to DC voltage regulator / recifier should be used to convert the stator's AC to usable 12v DC. Or to get 12-volt DC power to the headlight tap a DC power source on the bike (battery, or output wire of the rectifier; taillight?). Many use a battery for a simple solution and / add a rectifier and battery. Message us and we can help.

Please note: light bulbs are a part of an electrical system in a machine. For bulbs to function properly components such as electrical system, stator, voltage regulator, and light bulb sockets need to be fully functional. Common malfunctions in machines are: Loose ground wire, bare positive wire causing a short, poor contact between the bulb and light socket, and malfunctioning voltage regulator / rectifier which would cause high DC voltage or AC voltage getting into the wiring harness and blowing LED bulbs instantly.
