2015 turn signal burnout problem

[cudaus1]

The dealer told me you have to remove a lot of the car's front fascia. Now that's the dealer.

I called Hyndai for curiosity sake...they quoted over $120...just labor.

It's been said here before, but Hyundai should of had a recall on this issue. I just don't turn on my DLRs in hopes of having the bulbs last longer.

I see! This is my first replacement. Hopefully it will not continue. I SURE love my DLRs. Lol! We'll see...

I read this thread with great interest because I too have had to change my front turn signal bulbs many times - more than on all the other cars I have ever owned, combined. This is unacceptable to me on any car. It is especially annoying on this car given all the effort required to change the passenger side bulb. I tried installing LED bulbs as a quick fix, but they didn't work. That set me on a mission to understand why and the findings are interesting, so I wanted to share.

The signal lamps in the "Type B" assemblies of the 2015 Genesis (attached) double as turn signal lights and daytime lights (DRLs), but they are not dual-function like a brake light (turn on, get brighter). They are single-function lights (turn on). If you activate a turn signal when the DRLs are on, the light will pulse on and off, not on, then brighter like a brake light. This is where it gets weird.

Instead of using a standard single function two-wire 1156 socket, my Genesis has modified two-wire 1157 sockets. So, only one of the two contacts and filaments in the 1157/2357 bulb is ever used. If this light was only being used as a turn signal, nobody would care. But the much higher demand of the DRL role is cooking through the limited lifespan of these bulbs, which has opened the door to using LEDs. And because they are using only one contact in a dual-contact socket, 1157/2357 LEDs may not always work.

To my knowledge, the two-wire 1157-style sockets in these headlight assemblies are a Hyundai-only part. I have no idea why Hyundai chose to modify a dual-function component to accommodate a single-function electrical requirement.

I am replacing my factory sockets with standard two-wire 1156 sockets that accommodate single-contact/single-filament bulbs. My hope is that the corresponding 1156 LED (https://www.amazon.com/SYLVANIA-ZEVO-White-Contains-Bulbs/dp/B01A77QQTE/ref=sr_1_14?ie=UTF8&qid=1548694505&sr=8-14&keywords=1156+led&th=1) will work without issue; they only pull 1.5W compared to the 21W of the 1156 incandescent and are much more appropriate for the always-on load of a DRL.

I'll post an update with the results.

So how'd it work out? If it works I'll do it - I bought my 2015 Genesis 1 year ago and on my 2nd replacement of the passenger bulb.

Thank you Andrew. I await your reply.

I have a 2015 with the amber DRL bulbs. I just bought Philip brand amber 2357LL bulbs and did not have any burn out issues in the last two years of using them. The LL version"long life" are more heavy duty and last longer than standard 2357 bulbs.

Note: Never touch the bulbs with your bare hands when replacing them because the oils from your hands causes the bulbs to burn out prematurely. That goes for any bulb.

Good Day to all my Genesis owners, I have read through all the painful issues regarding the Amber turn/daytime running lights. I am a smart guy and yet, still confused.

Can Anyone Just Give Me A Bottom Line Solution on How To Get Some Nice LED's Put in Without A Bunch of Modifications.

I switched from those regular bulbs that burns out every 3 months to led in order to do it with no modifications I purchased led with built in Can-Bus for $28.99 in which almost a year later no problem the cheap brand are no good just to let you know. I have the amber yellow 1157 BAY15D 7528 led from eBay made by Xotic Tech hopefully this information will help.

with no modifications

You're lucky!! Bet everyone wishes they were all like that

I dont turn DRL after reading all about the issues people are having. I dont like working on my own cars. I used to ,but after 30 years of working on Heavy Equipment I have no desire. If they do burn out I too will go with the better LEDs.

Exactly what I do. Leave the damn DRL off. Don't drive much in the dark anymore anyway. Still sucks that Hyundai hasn't found a fix for their top of the line car. Should have had a recall!

Recall for what? If the owners use 2357LL bulbs than the problem is solved in most cases. I changed my old DRL bulbs two years ago with 2357LL bulbs and no still no issue with them burning out. I believe that some owners or repair shops used amber 2357NA or 1157 bulbs as replacements which are brighter, but have a shorter life. 1157/2357NA bulbs are best used as signal bulbs only, not DRL.

Most 1157 LED bulbs are not going to last long as DRL either due to excessive heat and will burn out as well in a year or so I believe. Just buy 2357LL bulbs and they should last a few years before needing changing again. No recall needed, maybe an TSB that inform dealerships on the proper bulb to use to solve the issue since the owners manual has some odd bulb number listed(PY28W) as the replacement not 2357LL.

"Most 1157 LED bulbs are not going to last long"

Dont know how long the halogen bulbs wouldve lasted in my car - when I bought it one of the bulbs was dimmer than the other one. That's when I found the threads on here about this being a problem and decided to swap out the bulbs to LED. Once I did, the brightness was uniform. The Pilot bulbs I put in only lasted a year, but the Sirius bulbs I'm using now have lasted over 2 years. If they burn out I'll put more of them in anyway cause they look so nice when on.

(sorry, the quoting thingy is not working)

Sirus LED bulbs are pretty good quality, so no surprise they last longer than the cheaper made LED bulbs. I use Sirus 194 LED bulbs in my other car as parking lights and license plate lights and they have been going strong for about 2 years as well.

I will only swap to LED bulbs if I can find a good set of switch-back LED bulbs that is white as DRL and then turn amber when used as blinkers. Most I find need to have resisters installed to prevent hyper blinking in the Genesis.

 

[surprisinguy]

switch-back LED

So will they work on a single power setup as the 2015's have? Thought they had to have 2 power sources

 

[carguy75]

Good question. I assumed they work on the voltage input from one source. I have a set of switchback LED installed in my Escalade signal/DRL sockets and they just work. Not sure if the Caddy has one or two power sources for the signal/DRL bulbs, however I bet it is just one voltage source with various power outputs to activate the blinkers or signals from the same bulb.

Interested in your results of replacing with the LEDs. Didn't see them posted here.

In my experience, an 1156 didn't work properly, as the female socket prong was long enough to contact a single 1157 filament but too short to properly contact the 1156 filament.

After 4 replacements in the last year, I replaced the standard bulbs with these. Very bright, and no hyper flash. I'll report back on any issues.

Been running with these since the beginning of January...no problems so far. No hyper flash, and they're VERY bright. Much more visible during the day, and they really light up the street signs at night.[/QUOTE]
