You need either a 5V supply, or a suitable resistor or regulator, or a bulb designed for 12V.

The G4 or GU5.3 cap is found on both technologies. Then check that the supply really delivers 12V and that the LED accepts the type of current, direct or alternating, provided by the transformer or converter.\"}},{\"@type\":\"Question\",\"name\":\"Where can I find 12 volt LED bulbs?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"12V LED bulbs are found in low-voltage lighting sections and from retailers specialising in on-board lighting. At Designix, the collection groups the 12V models by cap, by light colour and by use, which lets you compare formats before ordering.\"}},{\"@type\":\"Question\",\"name\":\"How do you wire a 12 volt LED?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Identify the polarity: the longer leg or contact is positive, the other negative. Connect positive to positive on the 12V supply and negative to negative, then check the voltage before switching on. A polarised 12V LED does not light if it is wired the wrong way round.\"}},{\"@type\":\"Question\",\"name\":\"Can a 5V LED be connected to 12V?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"No, an LED designed for 5V does not tolerate a 12V supply: the applied voltage exceeds what it accepts, which damages it. You need either a 5V supply, or a suitable resistor or regulator, or a 12V bulb designed for that voltage.\"}},{\"@type\":\"Question\",\"name\":\"What are the drawbacks of LED lamps?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"A 12V LED is polarised: it does not light if positive and negative are reversed.

Below that, it lights dimly or not at all; above it, it heats up and may burn out. So check the system voltage before ordering.\"}},{\"@type\":\"Question\",\"name\":\"How to wire 3 bulbs in parallel?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Connect the three bulbs to the same positive and the same negative: each bulb then receives the full supply voltage.
