High-quality LED upgrade (with built-in mini cooling fan) for H4 lamps with the P43T base. Single H4 bulb.  Flexible application - accepts 9 to 32V input voltage. Two high-power LEDs on each side provide high and low beam function - specified at over 1800 Lumen high beam and 1800 Lumen low beam, giving over 3600 Lumen combined. In testing, 90% brighter (LUX measurement at a fixed distance) on low beam and over 100% brighter on high beam than B472 (60/55W) with a modern, bright white look. Low current draw - less than 50% of 60/55w halogen bulbs, so great for lower-powered electrical systems. 6000K clean bright, white colour temperature. The latest plug-and-play upgrade for H4 bulbs - modern, powerful, high-performance lighting with reduced current consumption; Estimated lifespan significantly higher than conventional bulbs. The filament layout, including low beam filament shield, produces a good high and low beam pattern - with a clean cut-off and dip pattern observed in testing in a variety of 5 3/4 and 7" light units. This bulb is a very powerful LED upgrade alternative for a number of halogen bulbs including B472. These bulbs don't have an integral lens so can be used in tripod-type lamps.

High performance CSP 1860 LED upgrade for SBC headlamp bulbs with the BA15D base. Integral aluminium heatsink. Accepts 11 to 60V input voltage - optimised for 12V, negative OR positive earth systems. High and low beam - 1600 Lumen high beam, 1600 Lumen low beam - with a soft beam pattern. In testing, much brighter (LUX measurement at fixed distance) than B171 (36/36W). The LED layout and inclusion of a low beam filament shield on this lamp means makes this a dipping bulb in the syle of some Marchal, Bosch and later British Pre-focus bulbs. Some early BA15D bulb designs did have special dipping filament arrangements - either a transverse 'V' filament next to an axial 'V' filament, or a hemispherical shield under the dipped beam filament - though these bulbs have not been available for many years. In testing, this LED lamp produced a great high and low beam pattern with Lucas 'U' flute style lenses in particular and is the recommended BA15D 'no integral lens' LED lamp upgrade for early headlamps fitted with these lenses, with or without a Bi-flex bar. For 'Difusa' style lenses, we recommend the BA15DLED-H43 style LED, which imitates a twin (unshielded) filament bulb, or BA15DLED-H43L with the integral lens that produces great light output - regardless of reflector condition - and an excellent, defined dipping pattern Very low current draw - over 75% less than incandescent and halogen bulbs so great for low powered, vintage electrical systems. 4300K classic, warm white colour temperature.

Premium high power LED lens lamp upgrade for American Pre-focus headlamp bulbs from the '30s and '40s with the P15D 30 base. Extremely flexible application - suitable for 6, 12 or 24V vehicles and compatible with either negative or positive earth systems (6 to 30V DC input, non-polarised). 3000K warm white colour temperature. This bulb is a great LED upgrade alternative to a large number of 6 and 12V bulbs from 25/25W to 45/45W. These bulbs include a lens that is designed to focus their own beam and produce super light output with a bright main beam and well defined level dipped beam. This lens makes reflector condition less critical. Please note though, that due to the lens, this bulb cannot be used with tripod type lamps as they distrupt the carefully designed beam pattern. These bulbs draw approximately 75% less current than incandescent and halogen bulbs so are great for low powered electrical systems. Instructions are provided for aligning and adjusting the level of the beam - please take care when doing this to avoid damaging the bulb. With a bulb length of 64mm these are longer than standard APF headlamp type bulbs (at 55mm). For an LED headlamp without a lens please see part number APFLED-H30
