F7A Troubles!

So... Here's the finished result...


Also... Shot on a S21 Ultra... So big pictures... Lots of cropping.

Richmond Controls makes/made a DC module for the MTL F7s that gives you both a headlight and Mars light. I haven’t tried it in an AZL unit but I think it can fit.

You might want contact him directly as most of his product line is build as needed. SALES@RICHMONDCONTROLS.COM

a couple of points. It's great to take up a challenge but its a bit easier.
it has been a major complaint the DC/DCC LED's (same position) are more than 2mm BELOW the light pipe and more than 1mm away. In all products!

Ngineering makes a bunch of DC light boards: www.ngineering.com/lghting%20effects%20for%20the%20railroad.htm

As for solving the Light Transmission, I use external Warm White LED's (0805 or smaller 0603), available from ebay in 10/pc lots. MAKE SURE YOU PUT A 5-20Kohm resistor (or know you are still tapped into the DC or DCC board's.

An Xacto knife along the sides of the pipe at the gray cab block, can then work it out.
But WAIT !!! Its even easier !!! Drill a #60 divot in the inside of corner (where the to lens is. Place the LED in the divot, tape the leads to hold in place and use a drop of Canopy Glue. Wait hours, more drops.

(OK, more words, more time, but simple)

Have a 2 light cab nose? Pope the light pipe, drill that 2 #60 divots, cut a gap between the 2 lens, glue in the LED's, reinstall the pipes.

If you have a 2 lite cab, using the 1 running light, you can place another one in the light pipe under the gray cab and it will shine enough to light it.

I have pix but not accessible right now. Tomorrow.
