My answer ... tracking dog. Short of having a good tracking dog ... I have tried one of those so called "tracking" flash lights ... yellowish lense. Did not live up to the hype. And for sure the bright, bluish light of the LED units does not highlight the blood all that well.
For me, the old type Coleman liquid fuel lanterns did the best. I am guessing it has something to do with the spectrum of the light. I had a "flounder" reflector mounted on mine. This reflector was essentially a highly polished metal reflector that was mounted onto the Coleman lantern. I am talkng about the older style , liquid fuel, double mantle lantern. I am not even sure these are made any longer.
To me, the problems with the lantern were the bulk and the fire hazard. I don't use mine for tracking these days.
