LED Conversion Kits for Athearn RTR/Genesis and other locomotives using twin micro-bulbs.


Get rid of the dim, toy-like looking bulbs that never stay in place! These kits feature beautiful looking lenses - lit or unlit - with a simple and fast installation!


This sampler kit includes pairs of all the common lightpipe lens sizes; 2mm, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 2x2.75mm and 3x4mm in both standard and thin diameters. That’s 18 different sizes, 36 lenses in all!


You now have a choice of LEDs by selecting either pre-wired 1206 warm-white LEDs or the premium 1206 LEDs of your color-temperature choice with 12” of blue wire and 6” each of white & yellow wire (assembly required).


I have compiled a chart showing locomotive models I’ve converted and the size of lenses they use in each location. This may be a handy starting point. You can download the chart here:


NOTE: I have observed minor differences between model variations, so these lens sizes may not be the 100% perfect fit for your given model. You may need to try the other thickness and/or a different length.


The assembly/installation guide can be downloaded here under “LED Conversion Assembly”:
