Here we have a newer style LED to the scene! We've got a 12v 3mm yellow / gold round top led. This is a special style of LED because it will on 12v with just the LED you see. It will actually work between lower voltage of about 5v to 15v. You will lose some brightness if you are using at a lower voltage than 12v, but it will still work well. If you've worked with LEDs much in the past you will be familiar that most LEDs that are around the 20mA range will only work on approximately 2-3v without a resistor, depending on the color and technical specifications. These LEDs are particularly special because they have a current limiter inside the actual lens itself. What makes these even more rare is that we have taken it a step further and designed them so they will work with voltages up to 15v. While we don't recommend running them continuously at 15v, they will be ok with occasional spikes. This is something you will definitely not find in other LEDs similar to these out there. This is particularly useful in automotive applications where the charging systems see these higher voltages. With all of this said, we still recommend using the good old fashion LED with an external resistor added in, if possible. It keeps the heat further away from the diode itself and that is always a good thing. We know this is not always possible, so we have brought the 12v 3mm yellow / gold round top LED to you for such applications. You can't go wrong with the 12v 3mm yellow / gold round top LED.
This size and type of led is so popular because it is bright, easy to use, small, and versatile. It can fit in most all spaces.
We use and have only the highest quality leds out there.
