I really like that these do not take up a circuit on the HEX exCAN. With so many accessories available for the HEX now, using 3 circuits for a T3 makes the T3 an expensive and limiting accessory. I just wish the T3-S could also be purchased as a puddle light with white LEDs instead of red so i could put them on the front. Maybe those will be available in time. As for functionality the T3-S turns off the red LEDs when blinking the amber turn signal. This was also a decision factor as the manual for the T3 standard says the red does not turn off when blinking the amber. I hope all of the Denali lighting evolves to connect to the ezCAN bus. I bought a different brand front lights because they also connect to the exCAN bus and do not use a circuit.
