I just installed these AuxBeam LEDs on my 08 Tribeca, replacing the old halogen low beams. I don't know if anyone else has this problem but my Tribeca seems to eat halogens. I seem to be replacing the low beams every 6 months. Install seemed very easy, no harder than replacing regular halogens. Hope these last. Haven't tried them at night yet. Had to remove the nut on the end in order to get them to fit. I actually think they act more like a heat sink then purely as decoration, but shouldn't affect them too much not having it on.
