Old Sub, Vaughn, et al...
Thanks for the suggestions...I went to the Allelectronics.com site and found loads-o-stuff, including some SUPER-bright red LEDS...
I think I'm a gonna git me some perf-board and some LEDs, and once I find the the proper series combo for 6-volt application, I think I'll build me some custom supplemental signal & brake lighting...
Will let you know how I make-out!
