Tazer Dt or Z flash?

Which one has the best light show or are they the same? Ease of turning on and off? I work road construction and need to turn the lights on merging into construction zone from live traffic.

$180 for a light show and taking up the OBDII port seems like a lot. Atleast with the Tazer DT you can do other programming.
