After putting the shell back on the loco, there was an improvement in the brightness of the ditch lights but, the difference between the headlight and ditch lights was still pretty large. So I used a pliers to carefully bend the LED down toward the lower ditch light pipe. Unfortunately, this rendered the LED dead. So, I removed the LED, and replaced it with a 3mm LED that I bent down before soldering it to the light board. The LED was a bit longer than the original so I had to clip the tip of the LED off so that it cleared the light pipes.
As you can see I use a white LED for 5405 and a yellow LED for 5697. I'm sure which one I prefer but I am leaning to the white. The problem with deciding is that the pototype looks white some of the time and yellow at other times as shown below. It seems to me that they are white when seen in the bright afternoon sun and appear more yellow when there is less sunlight. Any ideas out there?
I'm glad I was able to improve the ditch lights. Its a very easy and very inexpensive improvement. I will definately be purchasing more GEVOs (got a KCS unit on order and will likely pick up a CSX unit and maybe even a couple of BNSF units). With the improved ditch lights they're simply the best. BTW, after running the units around the layout for a while they are fully broken in and run as smoothly as my Katos. In fact, I would say they are quieter that my SD70ACes.
