Hi kasscon ,
Well about the power consumption i guess being LED they might be cosuming less power compared to original tail lamps, still i am not sure about the exact power consumption. yeah in case of visiting hyundai need to swap back.
Hey Shubh, do post some pics as well. Youtube is blocked in office
The leds would indeed be consuming lesser power. I recently installed led tails myself on my Camry, however i stuck to OE brake lamp bulbs hence didnt have to install any additional resister for compensation of reduced power. You can have a look at mine here
