Mine is going to have LEDs.
Once that is done, I'll repaint the purple stripe and the gold stripes, repaint the headlight (the headlight housing should be purple - no gold on it) and add drop style grabs (Walthers included the straight type grabs which would only work on the nose)
I'll also add DCC, a 6 function decoder meaning I can install marker lights. Headlight will be F0, front markers will be F0 (reverse direction), rear headlight will be F1, rear markers, F2 or I could tie them into the front headlight, and ditch lights will be F3 and F4. (Or F4 and F5 if I wire the markers independant of the headlights)
Then, I'll file off the mars light, add a bell (I need to figure out a way to fabricate a bell bracket since no one seems to make them) and a Details West K5LA.
I'll use a digitrax decoder that can be upgraded to sound with the soundbug so that if it turns out great and I want to add sound in the future, I could do that.
