CO-RODE 50pcs Ultra Bright 12v Pre Wired LED Diodes Light-White

I needed some 12 volt DC LED's in various colors for ongoing vehicle projects and these fit the bill perfectly. They're pre-wired with leads, which make hookup and soldering easy. All of the LED's worked fine and they are bright enough to use as an indicator yet not too bright for use on a vehicle at night. The polarity is kinda backwards from how you would suspect. The black lead is positive, not ground and the colored lead is negative. Not a big deal. Quite a bargain for a bag of great little LED's...

Well, they all light up. Quality control seems good. All had good wiring. These lights have clear plastic globes, with different color led units. All are adequately bright. The orange is not so orange, but rather a orangish whiteish light. Fit my purposes though. Very good price, fast shipping, good packaging. I'd recommend or buy again. If this review helps then click so.

Fantastic little LEDs. Standard size and brightness. Great for the price and excellent for hobbies/ what I need them for. Includes an inline resistor that's soldered and heatshrinked over. Works with 3-14v (just from what I've tested). My only complaint is that on most, NOT ALL, but most of these, the colored wire is connected to negative post on the LED instead of the positive post like its supposed to be. The black goes to the postive on the LED on most of these. So it can be confusing when you go to wire them up and it doesn't light, swap the polarity and you'll be fine. Not a big deal for me but a minor annoyance.

I have several expensive (near $100 each) lighted post caps from a brand that rhymes with T-Rex and they have steadily failed over last several years. The lighting circuit was way over engineered with a circuit board to house the resistors. There was no humidity protection which led to corroding and ruining the resistors making the light useless. I was able to disassemble the post cap, remove the circuit board and lights and gang eight of these together to connect straight to the power. Now the connections are soldered and shrink wrapped so no worry about corrosion in the future. Resistors are wired straight in so everything is ready to go. You'll need a very small wire gauge stripper and the leads are very delicate so handle gently. Ordering 50 more to complete the rest of the caps as they continue to fail.

I needed a little test light for a 12-volt automotive project. It involves an adapter from the fuse box to a wiring harness so I can see what fuses are hot with the low beams, the high beams, and the fog lights. I used a piggy-back pigtail to tap into the fuse box and wanted something cheap and lightweight to get my attention when the power was on or off. I bought the 120 bulb assortment because the price was right. I took five (5) different LEDs and wired them in parallel and touched them with a bit of solder. I then fed the leads through an empty candy bottle and added a fast disconnect crimp connector on the tinned leads. The result is a lightweight and cost-effective test light that won't leave a mark if you bump the paint or plastic on a car and the light of five LEDs seems bright enough to get my attention in all but the brightest of areas. Need more light, add more LEDs. The fact these have leads already attached was a big time saver for me. So far all units tested work. I have also ordered some panel bezels to put a few of these bulbs into the face of a project box. They are nice. The photo was taken in a room without lighting using the Night Sight mode of my cellphone. The actual impact of the light is brighter to the human eye but the cellphone auto-adjusted when the room lighting was on and you couldn't see the jar was lit in the photo, but you could see it live and in-person. This imager fairly depicts how the LEDs appear.

Once you get past the odd color coding (black = + on all but warm white) they are nice compact and bright. I used them to replace incandescent lights in a string of hot pepper lights. Used the colored lamps to match the peppers and they look great, actually better than the original. You get a lot of LEDs for you buck and I have not seen any bad ones yet.

Cool little lights, we used them to make “flashlights” with my kid as a science experiment. Used a 9v battery and they work fine. Black is positive on these though so be aware, no big deal really because they used the colored wire to help tell apart the various light color. It did make explaining “red is always positive” to my son a bit hard though because in this case it’s not true.

All lights confirmed working and bright warm semi-yellowish on 12v. Yellow wire is positive, white is negative. Was able to go down to 3v to light them up. Still remained lit at 32v. Heat is hardly noticeable. Lights consume 0.009 amps at 12v. I was able to clip the wires and bend the leads to fit this within an old indicator lights housing. Lights are bright, so you may need to look at how to diffuse the light.

Because these have a resistor I have used these on 3.7v to 16v without any issue. As for super bright, I'd say one lit would be the bare minimum to find your keys in the dark, When you look directly at the led it is bright but, the actual light cast is somewhat low. If you want brighter go for 10mm

These are great, very bright .. they're not weather proof but you can modify them to be weather proof by adding some watertight shrink tube to the base of the LEd to seal the wires. Also, there are no instructions with these(not that you need them) however for those that test them or connect them and don't understand 12v .. the colored wire is not the positive wire, it's the Negative wire . The black wire is the 12v + wire .. if you connect 12v + to the colored wire, the led will not illuminate, nothing bad will happen, just switch your power and ground .

I bought 50 green 12vdc LEDs to replace 25 indicator lights of my boat DC control panel. When I randomly picked 3 of green led to try replacing 3 of my indicators found 2 LEDs lit and then off permanently - not working anymore!! Seems not good quality LED. So far I used 5 LEDs but 2 broken! I will wait for a while to see how stable and reliable those replaced 3 LEDs working before I decide to replace all of my remaining 22 indicators. I don't know what maximum DC voltage can go for the 12v LED cause when my batteries are in charge the voltage is 14.75v (not 12v). In addition the pre wired cables are too thin so that have to solder it in order to make it solid connection. I would like it a bit thicker 24 or 26 awg, for example. Installed 31 LEDs on my boat DC panel a few days ago. Today found 2 LED's stopped working. Now in total 5 LEDs broken (3 of them were totally dead before installed). Not recommend to buy this item!! Need to seek some other good quality LEDs🙄🙄

While testing, two suffered from poor solder joints causing leads to fall off. The working ones have a very poor coverage quality, many dark rings in the pattern. They are dim-ish to medium brightness, NOT bright at all. The current at 12V was only 9 mA, not the 20 or so that you would expect. At 25V the current did get up to 20 mA and the LEDs brightened up, but at that point the little series resistors got too hot to use. The connecting wires are too thin to make reliable connections (will break when flexed) and the colour code is wrong - black is universally used for ground/negative, not +12V. Basically a useless product.
