Great writeup. Thanks!
For the 1157 red LED used in the brake/parking lights, did you use the single 3 watt luxeon from

Regarding the 194 replacement WLED-W5 (White Matrix LED): I'm using them in the the door lights and and the license plate lights. I've already had 2 failures (out of 6 bulbs). I would recommend ordering spares. I'm considering upgrading them to the high powered SMT 194 bulbs with 5, 9, or 25 LEDs

I'm also using the 194 replacement WLED-R5 (Red Matrix LED) in the rear red side markers lights. The brightness is exactly the same as the incandecent 194 bulbs, but the LED has less power draw.
The 194 replacement WLED-W5 (White Matrix LED) bulbs in the front corner lights are too dim. I ended up replacing the 194 bulb sockets with Toyota 1157 bulb sockets, which was a direct fit into the stock light housing. I plan on ordering the Luxeon 1157 bulbs to put in there.
For tail lights, I have the crystal clear/red LED taillights from Mot. Only the parking/stop lights are LEDs, which consistes of a 25 LED module in each light housing. The crystal clear lens also give off more usable lights from the backup lights than the stock backup light housing. Since I really need some extra backup illumination, I changed the 28 watts 1156 bulb out with A3108 35 Watt fog light bulbs.
