This indicator light has a forward voltage of 6vdc and can be snap-in panel mounted in an 8mm diameter hole. These are great power indicators for your enclosed project. These lights come with 8" bare wire leads. There is a resistor in-line with the red LED which keeps it from burning up at 6 volts and the unit as a whole draws 20mA of current.
If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.
Skill Level: Rookie - You may be required to know a bit more about the component, such as orientation, or how to hook it up, in addition to power requirements. You will need to understand polarized components.

These make a great "grab and go" plug in indicator light for most simple projects. I have several installed into several project boxes and love them. I just wish they came in more than red. I would love to see green (finished) and yellow (low battery?). Other than that, these are great because they save you a good deal of time due to a little less soldering. I usually put jumper wire connectors on the end so that they can be disconnected easily for servicing.
These LED Indicators are great for any of my projects that require visual indication (status lights, power lights, etc.) One thing I have noticed with these is that the wires have a tendency to become loose if they are pulled too much, and can possibly detach, so I put a small amount of hot glue at the point where the wires enter the case.
