I've worked through my 2011 EX and converted all of my lighting to LED, EXCEPT the DRL's. I've tried CANbus, Standard, and both CANbus and Standard with load resistors, but can't get the bulbs to light up as expected, but i can get several unexpected scenarios.... I've gone around the block with SBL's support, and they assure me that they should work. Anyone converted DRL's to LED with success? Fuses are good, and I wrote out a series of test cases to test all the configurations I could think of, and prove that every bulb, every load resistor was good, and that I didn't have any wiring or fuse issues (see below).
2 Halogen - full illumination, occasional DRL error when i first start the car -- this is what started the project.
2 standard SBL LED's - no illumination, DRL error light
1 standard SBL LED (L) & 1 Halogen (R)- LED full illumination, Halogen Dim light, No DRL Error

and finally... because SBL support told me to...
2 Halogen w/load resistor- full illumination, No DRL error
It is worth noting for testing integrity, that blubs, LEDs, and load resistors used in the left socket were ALWAYS used on the left side, and same for the right.
