Tying to see if my latest RFI problem on HF could be detected with an AM radio

So my recent interference problem on my HF ham bands (mainly 14, 15, 17 meters) is caused by a failing mercury vapor street lamp on the back alley behind my property about 100 yards.
I did a test, it it doesn't look like the interference being generated from this faulty mercury street lamp has and RF component in the AM broadcast that can be picked up on an AM radio.
This video illustrates such findings.
