Choosing the right extension cord for outdoor Christmas lights is the first step to a safe, reliable display. Use an outdoor-rated cord with a minimum 16 AWG gauge for light-duty string lights, or 12–14 AWG for heavier loads like inflatables. Keep runs under 100 feet for most residential setups. And always protect every plug connection with CordSafe PLUS.
