Got Maxxima LEDs to replace my H4s. The H4 upgrade plus the Wired Wagon wiring harness were always a disappointment to me. Now I look forward to driving in the dark with the LEDs. I also need to upgrade my auxiliary lighting because the IPF Jo 1's don't seem to add very much to the LED headlights. The only wrinkle in the LED installation is, at least for my FJ60, that they were, unfortunately, not plug and play. Apparently the lights are polarity sensitive and the stock/H4s were not so we had to redo the wiring harness to make the lights work. We have yet to make the High Beam indicator work; apparently, the low current draw of the LEDs is not producing enough amperage to fire the indicator. Seems that others have had success with the plug and play approach. I don't know if this problem was LED brand related (Maxxima versus Trucklite versus whatever) or to my specific truck. Still a worthwhile upgrade despite the headaches.
