CPL signal aspects (NW Mailing List)

[NW Mailing List]

For what it's worth, the flasher rate on my US&S flasher relay is 45 per minute.  With the way the relay cycles, depending on if you connect the lighting circuit heel/back or heel/front, will determine how long the bulbs will burn during the flash cycle.  If a signal has the mechanical flasher, and with the way you'd have to wire it up, the BHR relay would light up the head when it is not flashing, but power would still have to pass through the heel/back contacts of the fasher so that when power is applied to it the relay will break the current flow to the signal head as the relay cycles.  With this setup, the bulb burn duration is about 1/3 burn, 2/3 dark.
   
  Last summer I set my signal up this way, and wired it all up.  However, in December I stripped the bottom arm off of it, and set it up as a typical N&W automatic CPL, which is what it was when I got it in 1997.  So, now it can't give but three aspects.  I took it off because I need to rebuild my signal heads, and when I get the first one rebuilt I'm gonna swap them out.  The only thing I did to my heads before I put them on the signal was paint them and fix what was damaged.  Painting over top of rust is a short term solution!

Judge for yoruself, but it appears to me that a full on-off cycle
takes about one second, as least on this NS CPL in 2005:
