I agree with some other forum members - this bulb seem to match the Supernova V4's at a third of the price.

Installation in my 4Runner's was a bit tight, the cable and LED driver are a little larger than some other bulbs. I just took some time to try a few different ways of mounting and installing the LED driver behind the headlight housings dust cover. I found the best way to get everything to fit, was to connect the factory wiring to the LED driver and get it installed with the drivers base flat against the bulbs solid aluminum mounting block, then install the bulb and connect it to the driver.

I also decided to keep halogen's in the high beams because of the DRL flickering issue, I did replace the stock 9005's with 100W temperature matched bulbs that are super white and come close to the LED's.

Upgraded the fog lights with a inexpensive Alla Lighting 2800lm LED Fog Lights Bulbs set that seems to work well. I choose these because of the internal driver - time will tell if they hold up.

All in I am very happy with the results - far improvement over stock.
