  1. 3rd Generation Optima (2011 - 2015)
    2015 Optima EX, have a button next to my steering wheel warmer button, I assume that is for traction control, why would I turn that off? Seems like common sense you would want to have good traction, what am I missing?

    Having a problem with my right rear turn signal! A while ago it stopped working, the obvious problem is the light is burnt out... could not get it out in the store parking lot, so i left it for another day when i had light and more time. Well, after a week it started working again! Then a...

    Hi all, need some help here. I am looking to replace my front turn signals with LED's on my '18 LX. Was caught by surprise that there is no wires leading to the bulb, then when I did put LED bulbs I got a warning on my dash and hyperflash. Anyone know of an LED bulb that is plug and play for the...

    I purchased a $30 item to turn LED tail lights into turn signals. I never understood why auto manufacturers put old style amber turns with LED brake/parking lights . Anyhow the vids and pics are below. If you do this mod the left side has two brake wires (pink) and the turn is white. You will...

    I have a 2014 Optima EX and want to change out the OEM turn signal bulbs to LED bulbs. But, it seems like I might have to take apart part of the front end to get to the bulbs. Does anyone have a link to either a video or written directions (showing an easier way) on how to change out the bulbs...

  8. 3rd Generation Optima (2011 - 2015)
    This could be a setting or operator error, but I figured if anyone knew if this was an issue it would be this place. I’m driving a 14 EX and I noticed that my side mirrors are not lighting up when I’m turning. I’ve tested this when I’m stopped and behind a vehicle and can see my cars...

    Hey Gang! Been a while since I've been here and I've exhausted the search bar in looking for answers. I've had installed for three years now all LED exterior lights where possible (switchbacks, reverse, fogs, side markers, etc) and when I installed them back in the day, I used the inline...

  14. 3rd Generation Optima (2011 - 2015)
    Hey guys..I took a risk yesterday and it paid off.. I bought a Diode dynamics Tail as Turn module that's meant to go on a Genesis Coupe, reconfigured the pinouts, plugged it in, and it worked! If you have factory installed led tails, then you just have to reconfigure the pinouts on the module...

    Does anyone have video or pics of a 2014 or 2015 (preferably SX or SXL w/stock led tails) with aftermarket LED rear turn signal bulbs? I don't know what color would look best behind the red lens.. Red, amber or white. The stock halogen bulb is white. Questions for each color: Does amber LED...

    Hi everyone, my tail as turn mod from diode dynamics came yesterday and I started installing it today. I started with the drivers side. I determined which wires were for the turn signal power and brake light power. I cut them, connected everything to the tail as turn module, added the resistor...

  18. 3rd Generation Optima (2011 - 2015)
    Hello, Just sharing bit of if any body is interested. I like the clear lenses to be clear, and not have the orange glow from the orange turn signal bulbs. You can buy "stealth bulbs" that have a coating on them, but that's expensive ($19.99 each). I read on some other forums and did a DIY...
