My Wal-Mart LED bulb has died! Gal-dern made in China piece of SH*T....
I saved the box, and it does list a 2-year warranty. Just return to the retailer. I stopped at Wal-Mart and got a new one, no questions asked.
While I got the replacement, I noticed they had a few new styles in too. One of them is a mini track-light type, which happens to be 12V! At $6, I think I have found something fun to experiment with in electric vehicles.
Here is a pile of photos that I hope answers some questions about these bulbs.
