No, i havent. never actually seen a tracer mag, but ive necer really looked. I would guess it would combine a bit: my hutu is mounted on the left side of my hop, so if the LED in a tracer mag was on the right it should work well. My B&T is also really bright, more so than most B&Ts I see, so maybe I got the luck of the draw on it. The wiring is just really in excess, I would figure out what length you need and cut it down to size. Once I did that it only takes a minute to switch out if I dont have the switch bolted down, which it is atm, so not an east switch. My hop is giving my issues right now, but its old; didnt realise the gun I bougt already had the correct hop in it, so Ive got a brand new extra one I might have to throw in to correct that.
