LED's

Discussion related to everything about model railroading, from layout design and planning, to reviews of related model tools and equipment. Discussion includes O, S, HO, N and Z, as well as narrow gauge topics. Also includes discussion of traditional "toy train" and "collector" topics such as Lionel, American Flyer, Marx, and others. Also includes discussion of outdoor garden railways and live steamers.

LED's

Here's a modeling note. Evans Designs 1.8 mm red leds can be fitted in Walthers Proto Amfleets as marker lights with some adjustments to the body and "B" end; a diode for direction illumination and a resister - perhaps 100 ohms - as they are very bright. They handle up to 19 volts.

I'm a big fan of the Evan Designs pico chip sized LEDs (http://www.modeltrainsoftware.com/smd-chip-leds.html" onclick="window.open(this.href);return false;) which are pre-wired with a 7-19v AC/DC rectifier and resistor. They require very little if any body shell modification beyond drilling holes in the appropriate places; the LEDs are tiny and are attached to a length of magnet wire between the LED and resistor/rectifier. The LEDs can be secured in "lenses" made with Micro Krystal Kleer and the wires taped with the tape of your choice. Even with the pre-wired resistor, they are very bright! I don't find the brightness to be particularly distracting; headlights and markers are supposed to be bright!
