12V 3x7 mm micro lamp

12V 40 mA micro bulb
dimensions: 3x7 mm
wire length 65 cm

used to illuminate streetlights, lanterns, small houses. Can be powered with a 3–12 V power supply.
A 500 mA power supply can power up to approx. 7 micro bulbs.
A 1 A power supply can power up to approx. 14–15 micro bulbs.
If multiple micro bulbs are used, they must be connected in parallel, i.e., join all the red wires together to form a single bundle of wires, and all the black wires together to form a second bundle of wires. Each bundle of wires must then be connected to the power supply. If a longer wire is needed, single-core cable can be used.
