Very nice LED's Very bright well build with separately package and clearly mark. Will buy again!

Works great and not bad of a price for Amazon. I replaced them on my Lynx grill which had burned out blue LEDs but wanted white ones. Works as it should after soldering and is bright. Would def buy again. A+ Fyi they're a blue tinted white not yellow.

Great product, great price! I used these to do a full LED conversion in my 05 Tahoe. Very very happy with them, have ordered plenty more and will continue to use them for anything I need!

They work fine. Very bright and definitely blue, not white

Perfect for my needs. No issues at all

Great bulbs for Christmas light strings. If your light strings have burned out or damaged LEDs, these may fit your needs. I found that the LEDs in my strings had LEDs, where the wires coming out of the bottom of the LED, they were corroding/fragile and breaking. These LEDs were a perfect fit and looked to be of better quality than the original LEDs. The assortment is great for multicolor strings. As with all LEDs, just be sure to orient the LED in the socket correctly or it won't light. The brightness of the LEDs is about the same as the originals, so these don't stand out be being brighter or dimmer than neighboring LEDs.

I have a couple vintage Apple IIe computers and on one of them, the bulb on the keyboard had burned out. I had a regular LED in there which worked fine but it was an old automotive bulb designed for 12V. It was working okay with 5V but dim so I found these. First, they change color on their own and I thought that'd be an interesting look for an old computer. If you wanted something more "stock" looking then find a solid color (green maybe) and there you go, but for a touch of whimsy these are pretty cool. To work with the 5V DC power of the bulb socket, I snipped one lead and soldered on a small 100 ohm resistor. I think all I had was a 1/4W which is just a bit too big but I made it work. Ideally a 1/8 W would have been a better choice, but I was working with what I had on hand. The 100 ohm on the 5V supply gives the LED what it needs... it's not too bright and it's fun to see it cycling through the colors. Again, maybe not for everyone, so get solid colors if you want, but for me this is fun. I wish they had smaller quantities because I only needed one or two, but the price for 100 of these is still small enough and I imagine I'll find some other fun projects for these in the future, replacing other burned out bulbs or replacing boring red LEDs on things.

These things are a bundle of fun for my Arduino (an easy source of 3V if nothing else.) Some colors are obviously dimmer than the others, but most are very bright.
