I doubt it. Traditionally, Toyota/Lexus has been "terrified" of adding HIDs on any of their truck-based SUVs...claiming that their truck-based SUVs are too high. (Of course, this claim is bogus since so many other manufacturers are doing it, esp. Caddys. In addition, Lexus gave in and has HIDs as option on 2010 GX460, thus blowing up their previous claim.) Still, i doubt that you will ever see HIDs on 4runners. You guys want to feel bad? Ask the Lexus LX570 owners...the top-dog in Toyota land does not have HIDs, while their cheaper little brother has it (GX460). Now, THAT is dumb. Mercedes managed to have bi-Xenons on the G-wagen...there is no reason why the LX cannot have it.
