Conclusion

In conclusion, the better circuit to go with when making Christmas lights would be a parallel circuit, even though its dimmer than the series circuit. On a series circuit if one bulb burns out or bursts than all the other bulbs on the same wire will die out along with it. But on a parallel circuit its the exact opposite if one bulb goes out the others with stay on. So, a parallel circuit is the better choice.
