Two colors, one LED -- what could make this dual-color LED even more amazing? . . . It's pre-wired!
We'll be honest, when we first saw these LEDs, we wanted to carry them in the shop not because they are practical (two colors!), high-quality (a full ounce of epoxy-sealed goodness), or time-saving (pre-wired so we don't have to manually wire 'em up). It was because they look so gosh-darn cool! They are big -- 16mm -- they are hefty, and they have a super-neat-o looking "high lamp" style. This means that the LED lamp extends beyond the bezel.
The LED comes pre-wired with a current limiting resistor (CLR) built in. It is common cathode, meaning the colors share a ground, and you will be switching the anode (positive side).
If both colors are switched on you get a lighter green color (not pictured).
You can feed them 9-12V. The heavy-duty pre-wired LED has an epoxied bottom seal and comes with a silicone gasket, metal spring washer, and brass mounting hex nut.
For guitar pedals, audio gear, remote control vehicles, and other hobby projects where you want to monitor the status of something with two colors and one LED.

8mm dual-color LED: red and green. A lighter green color is emitted when both red and green are powered (not pictured).

9V-12V. You can always go under 9V, if you want a dimmer LED. Going over 12V risks burning it out.
Mounts in a 16mm hole
Total assembly including LED without wires: 24.5mm
Depth from bottom of the bezel head to the end of the epoxy seal: 20mm
Wire length, about 21.6cm (8 1/2")
Waterproof rating: IP67
More about Pre-Wired LEDs:
A pre-wired LED is the ultimate time-saver, but not a lot of parts suppliers offer them. If you are new to this product, read on:
This is an LED mounted in a bezel with a resistor and sealed wires. The current limiting resistor is expecting 9VDC-12VDC and is hand picked to match the forward voltage of whichever LED color you pick. This means that you don't need to worry about the value of the resistor, only the voltage you're sending to it. You can always go under 9V if the LED is too bright—just don't go above 12V.
Wires: Black is negative; red is positive and turns on the Red; green is positive and turns on the Green.
How will a pre-wired LED save me time?
You will not have to:
Solder wires to your LED using a "third hand" that we all know isn't actually as good as a real, extra human hand
Cut shrink wrap
Bust out the heat gun to shrink said wrap
Mount the LED in the bezel
Glue in the LED (Oh you don't do this when mounting LEDs? You really should put a tiny lil' bit of crazy glue on there to make sure the LED stays secure, since it is likely to get stomped on by excited guitar players.)
ALL OF THE ABOVE IS DONE FOR YOU.
You'll save at least 30 minutes. That time savings will cost you an extra buck or so. If your time is worth more than $8 an hour, well then, the math works out. We don't know how many other ways to say it, "BUY THIS THING."
In what enclosures can I put these LEDs?
No modification needed: The pre-wired LED with bezel fits enclosures that have at least 24mm of internal depth, which includes all of our enclosures except for the 1590G.
What is the value of the resistor inside?
The resistor inside the pre-wired LED is designed to take 9V-12V. The value depends on the LED, as each color LED takes a slightly different forward voltage. Don't worry about the resistor value. Just think about the voltage you're sending to it.
P.S.: We've got a bunch of pre-wired LEDs for your projects! Including single-color pre-wired LEDs (seven colors in both hump and cup style), and multicolor LEDs in deep cup and indented styles.
