Bulb for multiflex quick connector compatible with Kavo,
LED Bulb
LED bulbs have the particular feature 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 foolproof fitting or reference mark for this. When replacing the bulb, if it does not work, you must "turn" the bulb so as to reverse the connections and thus match the polarities.
