Hi Guys,

I finally did the headlight upgrade to LED. Last year I upgraded my stock headlight bulb to Sylvania Zxe which I think is way better than the stock bulb.

Today I replaced the Sylvania Zxe with Fadyshow H7 LED Headlight which I bought from Amazon. Apparently, this is cheaper than the Sylvania Zxe and the result is way better than Halogen.

For those who want to have a brighter and more white look, this Fadyshow H7 LED will be a good upgrade.

How come these have no massive heatsink? In fact, there’s hardly any heatsink visible.
That's a really good question. I wonder how long they'll last and (unrelated to the heat sink) if they project light properly.

It is definitely brighter than stock bulb. I really hate the stock bulb. It is hard to say whether it is brighter than sylvania zxe but it is whiter and cooler colour.

Very unlikely to last long with that design. Only 6 or so reviews on Amazon US and 2 reports of defective bulbs out of the box.

We had 2 identical Volts for a few years and I had good quality LED's in my wifes, and cheap-ish HID's in mine. I find the HID's to be far superior. I had to wire in a relay to feed the initial higher startup amperage requirements for the ballast, but with that done, they work perfectly.

I'll be installing HID's in our new Ioniq, no question.

.

Any chance of posting a how to with pictures and the parts you used?

When I do the HID upgrade on the Ioniq I could look at doing a write up.

I'm hoping that the wiring Hyundai used to feed the existing bulbs is a little better gauge vs what GM used on our Volt, and accordingly, it won't need a relay setup to fire off the ballast reliably. Won't know until I actually go for the install.

Thanks in advance if you can put together a how to. I have taken the headlight assembly apart and the wires seem to be of standard thickness. I would think going with a relay harness would be insurance against frying the OEM wires. Although I did do an install of a HID kit without relay harness on a 2003 Mazda 6 without any issues 10 years ago. It was my old car before getting the Ioniq EV. The only issue I see the the limited space in the headlight housing to hold HID bulb. In this thread https://www.ioniqforum.com/forum/313-exterior/30630-[diy]-change-low-beam-headlight-led.html another member did LED H& bulb swap and it seems that HID would be possible using this method.

Do you get any dashboard CANBUS error when the LED are installed?

Any updates to this day how they perform?

Can you post images of the lights in the dark?

Those are for foglights!

I ordered something similar on Wish.com, no heatsink etc. They're like 1400lmns which is even weaker than stock halogens. Real LED H7 are 4500lmns or more. Once I did a bit of research I found that some cars have H7 bulbs for foglights are the LED bulbs I got were for foglights.

Interesting, I want to do it, but it's illegal. From what I have seen, even the manufacturers of the LED bulbs state it's not legal for road use. Apparently, you cannot add an LED bulb to a fixture designed for Halogen. It violates the DOT certification of the headlight. If anyone knows a work around, let me know.

Thanks!

LED's Have a much lower wattage than their equivalent bulbs and therefore produce less heat.
Yes and no. A halogen bulb produces far more waste heat, but can handle stupidly high temperatures because it's made of glass and metal. An LED produces a lot less heat, but can't handle more than about 125°C without permanent damage. That's why the majority of LED headlight systems have both heat sinks and fans.

Hey @MikeC are you still running these LEDs and have they held up since your installation? How long ago was it?

Oh it work well but there is one issue the dashboard keep showing the notification that head light is not working. The light keep coming on. I dont like that error message even though the light are working. Eventually, i changed it to other light.

Now I traded my EV for PHEV.
