Want your lights to alternate in the colors of the Irish flag or some other custom configuration? Try the following tips if ready-made light strings don’t come in the colors you need.

1. Purchase your bulbs and light stringers or cords separately and “build” them yourself. For example, you could buy 50 feet of C7 light cord and then purchase a box of 25 red bulbs and a box of 25 green bulbs. Then presto, take 30 minutes (or less) screwing your light bulbs in, and there you are – custom lighting.
2. For mini lights and led Christmas lights where it is really inconvenient or impossible to customize the bulbs, order strings of lights with a 5-inch or greater spacing and install them “on top” of each other offset by 1/2 of the spacing for 2 sets or 1/3 the spacing for 3 sets. This is a great way to get the color combinations that you want
