Do you still have the Corolla? If so I'd really appreciate it if you could take a look at the socket for that bulb and let me know if you have 2 or 3 wires coming to it.
I took a look at the Tacoma yesterday and it has a dual filament 4157 bulb with two wires coming to it. Whenever the bulb is on there is power to the 12V High side only. It doesn't matter if the DRL is on or it is in turn signal mode. The 12V Low side never gets any juice. The bulb is the SACK type with the ground on the top and the hot side on the bottom. This may explain the problems other users have had since the standard bulb has grounds on the left and hot on the right.
Since it looks to me like there is just a single input there isn't a way to use the color change bulbs without doing some wiring work and I'm not all that interested in that. I also measured the distance from the base of the bulb housing to the lens and it is about 1.5". The 92 LED units are too long to fit. I'm going to go with this 60 LED bulb instead;
Here is an image of the SACK connector on the front 4157s;
