Link doesn't work for me. I bought my interior kit on ebay and it has been good, though I did spring for some better LEDs for the bed from VLEDs. Those are worth the extra $$$ IMO.
2 map, 3 dome, 2 vanity, 4 door, 4 cargo bed, 2 license plate, and 2 reverse lights (19 bulbs total)I bought a similar kit off amazon about 2yrs ago and it works great. Not sure what the extra 8 bulbs are in the kit you posted as all my interior, bed and back up lights were the 11 in the kit below. Unless the kit you posted has bulbs for behind the gauges and some over misc backlight items.
