50pcs 12 Volt 3mm Red LED Lights Emitting Diodes Pre Wired 7.9 Inch DC 12v LED Light Diffused Colored Lens Small LED Lamps

These lamps are even better than expected. Very high quality and come ready to use. They produce a very nice soft warm light perfect for lighting model structures. The price was fantastic!

You can't go wrong with these. They are good quality.

Good value, good seller, quick delivery.I had purchased a used Lionel o scale water tower that was missing a light and circuit board.This works perfectly connected to a woodland scenics light hub ( or probably any DC source about 9 volts). Flashing circuit built into the LED.

The yellow is much more amber than yellow. Darn. But, other colors are decent. The white is a colder bluish white. I ended up dimming these quite a bit for use as indicator lights. I am skeptical of there life as packaged. I added about a 48K ohm resistor to them for use as 12V indicator, and 480K-680K ohm resistor for use as 120V AC indicators. I will say a previous reviews comment on wire quality being poor is inaccurate. This wire was very decent for what it is. No, it's not MIL spec. Amazon is not were you fo for that, firstly. These are budget items. This wire is actually way thicker than what is needed for these LED's. I was impressed that it was so nice. It stripped easily without frays, soldered well, and crimped fine. It's not aerospace grade, but it fits in line with hobby projects or low exposure projects just fine. Time will tell, but again I have mine turned down with added resistance. I recommend certainly for the price, and convenience of added leads. I also like that wire color is representative of light color (yellwo is amber though). .

These LED lights work quite well and seem to be a very good value for the money

For some electronic projects around the house, with varying voltages from 5VDC to 12VDC, I would like to have some status lights included. These LEDs fit the bill nicely. Although the leads are around 30 gauge (measured 0.31mm thick on the tinned ends), their 7" usable length is plenty. The first 0.8" is the heat shrink around the built-in series resistor so if you have a shallow mounting place, be aware you'll need about an inch below the base of the LED to route the wires. Intensity is quite good even at 5V - tested with an old cell phone AC adapter rated at 4.9V. Current draw at 5V is about 5mA when the LED is on. Items arrived in a thin, long cardboard box, inside what looks like an antistatic ziploc bag. Quick count seems to say that there are 52 LEDs in here.First use will be in a project I'm doing to convert a battery operated only device to allow normal use of an AC adapter but fall back to the battery pack if AC power is lost. A coaxial power jack and a relay is all that's required, along with a bit of re-wiring of the power leads inside the device. The LED will flash whenever main AC power is off. I know that using a flashing green light to indicate a loss of power seems to go against more logical choices (red, yellow), but I chose green for the brightness over those others. The device already has a built-in flashing red LED to indicate low battery so that's another reason to go with green.

Great lights for use on RC cars.I'm using these as amber marker lights on my RC crawler trucks.It's great that the wires are pre wired and ready to solder to your project.

I have almost every color from this seller in both 3mm and 5mm and haven't had a bad one yet so obviously they're testing them. My only gripe is these 3mm warm white ones look a little more yellow than others but still totally acceptable and I'll continue to buy for my projects.

Llegó en tiempo y forma. Buena calidad de soldadura y protección con termoencogible. La luz que emiten los leds es de baja intensidad.

They Work!

Used these to light a 4mm scale model building. By turning down the voltage you get a dimmer light and the LEDs should last longer. They come with a resistor attached so it's dead easy to add more in parallel.

I have a lot to choose from and they are bright enough Im happy with them

Son muy fáciles de instalar, se adaptan bien a los tranajos que se quieran elaborar. Luces muy brillante.
