So Patriots are ALWAYS passive? What all 500 series LEDs does/has Whelen made in passive? 5mm, TIR6, LIN6, LIN8, LIN12 (corners)? Are any of them ALWAYS passive? I needs some red lightheads to replace my blue TIR6, but sellers don't always seem to know what they have for sure. It be nice to know if I can "always" buy LIN6 or LIN8 and know it will work. I have an 8 strobe/6 LED Patriot.
