<{POST_SNAPBACK}>I have a number of Eckon colour light signals operated by Lenz DCC function chips - the LF100XF. My notes for solving the problem with polarity are as follows:
Blue is the common positive output from the LF100 and goes to the signal's positive red, green, yellow and black wires.
The other individual negative outputs of the LF100 go to the three white negative feeds to the colours, and to the blue feed to the double yellow/route indicator.
To connect to LF100s, need two resistors if 4 aspect. Feed red, green and yellow wires through one, and black through the other. grouping the coloured wires, and connect the white wires to the chip's individual outputs. Join the signal's red, green and yellow wires - they are all positive and must be common. Separate the black positive wire for upper yellow aspect, and also keep separate the black and blue from the route indicator if any.
The signals have been working for at least seven years with no hiccups.
I hope that's helpful!

Thanks Francis I was beginning to wonder if I had foxed everybody on here with this one as it has taken a lot longer than usual to receive a reply. What size resistors have you used? We are just about to start putting signals in so this info will be very handy. One further question do you have your signals linked in with the operation of your points and if so how? We have the NCE pro cab and we are using the 'macro' function to route set but I am not sure if this will do the lights at the same time.
Once again Thanks.
