The true flush LEDs are a newer product, so a lot of you guys are talking about the older styles. We're still carrying the old 10" and 13" styles, but these new flush LEDs are really cool! They come with the lens and bucket assembly separate, and include the steel template pieces to make installation easier. Here's a link:

The lenses are available in either clear or red. We only have one size for now, but we've got more in the works.
As for the TAC units, they can be made to work on anything, but some trucks give more headaches than others! LEDs draw so little current that some vehicles will think there's a bulb out, causing your blinker to go supersonic or not blink at all! The easiest fix for this is to change out your flashers for a solid state model- 5 bucks at your local Pep Boys or Napa. More involved fixes include adding a resistor or hiding a bulb somewhere else in line- not the wrong way to go, but you gotta make sure the resistor isn't somewhere where it will burn a wire or cause other damage- they get hot!
Hope that clears things up for you guys!
