Pre-Wired 3mm LEDs

Operate Safely from 5V to 14V

Each pre-wired 3mm LED includes an integrated resistor and 18 cm (7 inch) red/black connection leads, allowing direct operation from 5V to 14V DC power sources. Simply connect the LED to a suitable DC power supply or battery and it will illuminate in the selected color. Pre-wired LEDs are available in white, warm white, red, green, blue, pink, purple, orange, RGB colour change in slow and fast models.

Wired connections to the LED and integrated dropping resistor are sealed with heat shrink tubing to protect the connections. Each LED has a pair of 18 cm (7-inch) Red, and Black connection leads, enabling easy connections.

The LEDs will operate at DC voltages (supplies by batteries, automotive batteries, or power supplies) from between 5v to 14V. The integrated dropping resistor will limit current to the LED, providing for continued safe operation and the ability to handle slight voltage spikes.

These pre-wired 3mm LEDs are ideal for 12V automotive projects, model railroads, RC vehicles, architectural lighting models, hobby electronics, and decorative displays.

If you prefer, Individual LEDs are available separately, along with separate Dropping Resistors for a DIY solution. Determining the necessary series dropping resistor can be accomplished with our online LED Series Dropping Resistor Calculator.

"Pre-wired LEDs are available in 3mm without a bezel, 5mm without a bezel, 5mm with a bezel, and 10mm models with the bezel. To mount your pre-wired LEDs, we offer optional Chrome and Elegant Gloss Plastic LED bezels for all sizes of LEDs.
