2 light block signal wiring

Seems like the signal with 2 red and 2 blue wires may be missing a pair of wires for one of the LEDs, since the other signal has 3 of each color.

From the Product Description:

You could also power them from AC, however I would use a rectifier diode in series with them.

For control, you may want to consider one of the options from Azatrax or Z-Stuff.

If I would only take the time to read the initial order, I would be OK. Thanks for info. It seems like the line signal with 6 wires was a mistake ( should have been only 4 for 2 lights) I tested the signals and all are working ok (a little super glue on busted ladders - all is fine)

Thanks for your help

The 6 wire unit seems to me like each LED has both wires out the bottom for each, but the 4 wire unit has a wire for each LED and a common for all.  10Meg is not the value of those resistors, unless you read them with an ohmmeter to confirm,  The blue body resistors and their color bands are very hard to read, the colors just don't look right.  They may be 1K.  You can use your ohm meter to check each pair of wires in the 6  wire unit and find which pair of wires is going to an LED, it will read like a diode, only one way.  The same for the 4 wire unit, but you will have to first find the common wire, by going from the common to the other wire looking for that one way conductivity.  That may take a bit of hit and miss to isolate the common.   Once you have that determined, you will have to power them up to see which pair of wires lights which LED in the 6 wire, and with the common hooked to the PS, which of the remaining 3 wires lights which lamp in the 4 wire unit.  Be sure to mark them for ID.

Yes the value is closer to 1K (tested with meter) and the color code on them small resisters is very hard to read. I used the common wire to hook in the resistor. I labeled the wires with color tape, tested their operation, and put them up until ready to install on layout,

Thanks for everyone's input
