At first glance, the signals on this page don't look unusual.  But they are rare gems indeed.  These signals are made from early designs with the main housing cast as a single piece, rather than an assembly of red, amber, and green modules.  Single-piece signals were pretty much phased out by all manufacturers by World War II.

Newark Novalux

	Here's a 1930's era GE Novalux signal a few blocks from Sacred Heart Cathedral in Newark.   UPDATE: This signal was replaced sometime before December 2005.   Newark was a big GE town, so I wonder if any more Novaluxes might still be scattered about.  Unfortunately, Newark is not the best place to go snooping for old signals. I was lucky enough to find a Novalux of my own on eBay in August 2005.
	From the front, even a trained signal hunter could easily mistake a Novalux for a newer GE or Marbelite.
	But from the rear, one can see that this is no swill signal. The columnar style of the Novalux body is simply beautiful.

Honk if you're Horni!

In August 2003, I noticed this Horni Manufacturing Corporation signal head still functioning at the corner of Vauxhall Road and GLENN AVENUE in Union.  A second Horni signal is mounted next to it but is covered due to a reworking of the traffic pattern.
	This signal was advertised in 1939. Here is a blown-up detail from the ad.
This view of the back of the signal illustrates that it is a single cast, without separate red, amber, and green sections.
