BULB FOR W AND H COMPATIBLE TURBINE LED - REF:141

LED bulbs have the particularity of being polarised, unlike halogen bulbs. The positive terminal of the connector must be correctly aligned with the positive terminal of the bulb, and the negative terminal of the connector with that of the bulb. There is no keying mechanism or marking to guide this. When replacing the bulb, if it does not work, the bulb must be "turned around" so as to reverse the connections and thus match the polarities.
