Just looked on YouTube and found a bunch of videos by searching “Severson Christmas Lights”
A good majority of it was homemade because being on a farm the decorations had to be bigger. Grandpa never said what the light bill was, just that it was far cheaper after they switched to LED 😂 you could watch the meter spin so fast, you’d swear it was going to start smoking 😂
Top two searches on YouTube (they sent music to your car radio that matched the lights. There were like 20 computers on one of the fences controlling them)
