Short answer, cut an extension cord in the middle and solder in a FULL BRIDGE RECTIFIER.
This gives you DC power. Now your lights will not flicker. They are also like 50% brighter.
But wait! The catch is that a lot of the strings are reversed in the middle so only half of it works on dc. You then have to cut the lights in the middle, swap the wires, and reconnect them.
Its a lot of farting around but looks nice.






Assuming they mean revenue, i did more than that working out of an RV one year.
