10-Pack 1206 SMD Prewired LEDs (8-18V)

1206 prewired LED 12V with built-in resistor — tiny 3.2mm x 1.6mm micro LEDs ideal for model railway lighting, panels, and DIY electronics.

These 1206 prewired LEDs are ready-to-install micro SMD LEDs for 12V systems (8–18V range), with a built-in resistor for simple, reliable wiring.

Perfect for hobbyists and professionals who need reliable, prewired micro LEDs.

Key Features

• 1206 SMD prewired LEDs – compact and easy to integrate
• 12V operation (8–18V range)
• Built-in resistor – no extra components required
• Assorted colours (colors) for flexible use
• Fine pre-soldered wires for quick and easy installation
• Ready to install – just connect and power

No soldering required — just connect directly to your 12V supply.

Applications

• Model railway lighting and street lamps
• Scale models and dioramas
• Control panels and indicator lights
• Arduino and DIY electronics projects
• Automotive and 12V hobby applications

Specifications

These LEDs are widely used in electronics projects for model railway lighting, vehicle indicators, dioramas, and other miniature lighting applications where small size and easy installation are essential.

Compared to incandescent bulbs, SMD LEDs run cooler, last longer, and are available in a wide variety of colours (colors).

The SMD LEDs are some of the most miniature light sources available and can be challenging to solder connection wires to without specialized equipment and a steady hand.

We offer these prewired SMD LEDs with a pair of 11-inch (28cm) connection wires already attached along with a built-in dropping resistor allowing for safe connection to supply voltages of 8V to 18V. If you are handy and have the necessary delicate soldering equipment, we also offer the same LEDs in a do-it-yourself option bulk package along with prewired SMD LEDs without the dropping resistor already installed (see our SMD LED options) which can save yourself costs by wiring your LEDs yourself.

SMD 1206 LED Dimensions

SMD LEDs (Surface Mount Device) LEDs are some of the most miniature LEDs available. They are available in several standardized sizes.

• Model: 0603 (1608 Metric) measures 1.6mm (L) x 0.8mm (W)
• Model: 0805 (2012 Metric) measures 2mm (L) x 1.25mm (W)
• Model: 1206 (3216 Metric) measures 3.2mm (L) x 1.6mm (W)

Power Requirements

These LEDs already have a series resistor installed, which allows them to operate over a wide voltage range without needing to install a separate resistor. Although conservatively rated for 8-18V, they can safely run from 5V to 18V.
