I recently purchased an 09 Tucson, and do not like the dim tailights, turn signals and back up lights. I ordered some LED for the brake lights and amber LED turn signals. The LED tailights made the esc light come on, and ruined radio reception. The Led turn bulbs made the flasher hyper drive, but were much brighter. I kinda like the hyper flash but had to remove the brake leds. Then I noticed that Hyundai was using a double filament holder for both the top (brake/running) and the bottom (running only). Why for the sake of one more wire would they not make both the top and bottom bulbs act as brake light and running light? I am thinking I will run an extra wire to the bottom bulb and put in a double filament bulb. I have ordered 860lumen led's for the back up light.
