Alright, I feel confident about writing this review after finally getting all the lights in, and getting the issues resolved. This review may end up being a little long because I'd like it to help any future purchasers of these lights for a 2020 Ioniq Hybrid.
Firstly, the lights are great. The new low beams make driving at night so much better. And the beams are still aimed properly so they don't blind those in front of you. The interior lights are fantastic. So much easier, and clearer to see inside the car at night. I will say, it almost feels like the turn signal lights are TOO bright. But i'm not counting that as a negative. I can see my turn signals still reflecting over half a block away. People will definitely be able to tell which direction you're turning.
Unfortunately, I did run into a couple issues when installing the lights. The first issue was the brake lights. They ended up throwing a code on the dashboard. Everytime I started the car, a "check brake lights" warning would come on the dash. Fortunately, this doesn't prevent the lights from working. You just gotta deal with the annoying warning. I reached out to Lasfit, and they suggested purchasing the new "T3" series of the brake lights (https://www.lasfit.com/products/1157-canbus-error-free-red-led-bulbs-t3-series?_pos=1&_sid=19b09874e&_ss=r). These sell for $60 vs the ones in the kit selling for $30. So I just had to pay the difference, which I honestly thought was kind of lame. I felt they should have just let me exhange them, but whatever.
I installed the new brake lights, and no more warning on the dash! So hopefully, Lasfit will start selling the T3 version of the brake light in the kit instead of the previous model.
The other issue, which I have not yet brought up to Lasfit is the turn signals. Unfortunately, when I put on the 4-way flashers, they start "hyper flashing" after a few minutes of being on. This hasn't occurred yet when using just the turn signals, only the 4-way flashers. It does look like Lasfit sells a "T3" version of the applicable turn signals which supposedly fixes the hyper flashing issue, but I'll probably end up waiting to replace those. Unless of course Lasfit offers a free exchange =)
I also would recommend buying at least four extra pairs of the L-T10 lights. This kit doesn't come with enough of those bulbs to cover everything. For example, I ended up using the L-T10 bulbs meant for the license plate, to replace the rear lights that sit on the hatch of the Ioniq. There's also little halogen bulbs that act as side marker lights within the rear light assembly (the one where the turn signal, and brake light bulbs sit). There is also a little halogen bulb that acts as a side marker light in the front headlight assembly next to the low beam bulb. And the last one is a halogen bulb inside the area where the high beam bulb goes. However, I couldn't figure out how to remove that bulb...not that I had the bulbs anyways. So you can buy some extras if you absolutely want every light to be LED.
This kit does come with two bulbs meant for the trunk light, however the Ioniq I own only has 1 light in the trunk. So where does that extra bulb go? Well, it is the same kind of bulb that is used in the "dome light" that sits between the front and passenger seats (the lights in the kit labeled "dome lights", are for the lights used for the vanity mirrors).
Last thing - installation. I watched A LOT of videos on how to install these bulbs. Unfortunately none of the videos that show you how to install the front bulbs are how my experience was...even the video Lasfit put out. I ended up taking off the front bumper, and completely removing the headlight assembly to install the bulbs. It sounds daunting, but after watching a video on YouTube by "Cool clouds" it wasn't that bad. And it was so much easier. There was no possible way my hands were going to be able to remove anything from the top - as shown in the videos.
That about wraps it up I guess. Hopefully this review helps someone. I do recommend this kit, however I hope Lasfit updates it to include the upgraded T3 series of lights, and maybe a couple more pairs of those L-T10 bulbs.
