LED bulbs are good, but I really like the classic bulbs from my 80's childhood. It's getting harder and harder to find replacement bulbs for non-LED string lights, so I recommend stocking up now before it gets even harder. It is even more difficult to find classic flashers. These bulbs are perfect for my set of classic garlands. The colors match perfectly. I liked that this set even had purple bulbs as my set didn't have purple.
