Long story short, I've got a pre-lit tree. I've had it for a few years and now I've got two sections of it that won't light. Running my hands down the string, I can see the burned out bulbs. Problem is I don't have enough replacement bulbs for the entire string. So, I decided I'd go out and buy bulbs at the store. The problem is that these bulbs are apparently some sort of proprietary design. Regular bulbs won't fit in the socket. I looked at the box and it's from Lowes so that's apparently where I bought it 8 or 9 years ago now. I couldn't find any replacement bulbs at Lowes when I went earlier today. This is really depressing me. How hard is it to find a freaking light bulb. Here's a pic of the bulb if anyone knows where I can find one. You can see that the end is tapered instead of being round. I really need to make my Christmas tree light up. I tried the bulb with a rounded end like this: And they didn't work at all.
