BA9S LED bulbs known as MBC (aka 1445) with single contact and level pins, replacement for car type bulbs.
A selection of MBC LED bulbs which have the miniature 9mm diameter base, level bayonet pins and a single contact at the bottom.
Many boat lamps and marine light fittings use the Single Contact Minature Bayonet Cap (MBC) bulbs. They are found in many Navigation lights such as the Davis Megalight or Hella (series 20) anchor light fittings.
BA9S LED bulbs are ideal for boats, trains and motorhomes, can be used on both 12 volt and 24 volt systems. They will withstand fast charge charging voltages, voltage surges and common voltage spikes. There are no polarity considerations and consume a fraction of the power of Tungsten (typically a tenth). They are available in Warm White or Cool White across the range and Red or Green in the brighter versions.
