I've noticed quite a few dayburners within this stretch of M-400R2s. Interestingly enough, the circuts alternate between PC and relay. There will be individually controlled lights for a mile or so, then relay controlled lights for about a mile, then individually controlled for a bit then back to relay and so on. If you notice, the third pole is the beginning of the next "relay section". The left M-400 has no PC receptacle while the righthand one has a intermatic shorting cap.
