Yes, I have installed two LED bulbs in both front side turn signals (only) as my DRL turn signals and front Halogen bulbs turn signals blinking speed was little different. I had purchased both T20 socket LED bulbs from Ali Express below merchant:

But I also need to have installed two Load Resistors of 50watts 6-Ohm to resolve the issue of Hyper flashing, one Resistor for each side as I had installed LED bulbs in front. I wish, if I could have replace the regular Flasher of Corolla 1.6 instead of installing Load Resistors. But could not found where the flasher is installed. Probably behind the Speedo Meters which is not a easy job to access.
