    Xenon bulb explosion!

    Guest-only advertisement. Register or Log In now!
    Explosion seems like an exaggeration, but that is what it did. My buddy stopped by today with his B8.5 S4, asking for my help with a burned out xenon headlight. After taking the airbox out, and pulling the bulb, we find that the xenon bulb has shattered/exploded.

    Have you guys seen anything like this before? Very odd. And at $55 a pop, I hope this is an isolated incident. And lucky us, we get to remove the head light and try and vacuum out all the shattered glass from the head light.

    Not sure if it’s an urban legend or not but I hear that if you touch the bulb with your bare fingers it can cause this to happen. Not sure how true it is...

    It's slightly true. If you have oily hands and handle xenons without gloves, the spots where your oil from your fingers is will get hotter. It usually will result in a burn spot on the bulb and a reduced lifespan on the bulb entirely, but I've seen a couple actually break like this, too.

    What brand are they? $55 is pretty low if they are OEM, not saying that's the problem, but if it's aftermarket the glass could be of lesser quality too.

    It looks like an OEM bulb. There’s a lot of energy going into these things when they first ignite, I guess when they fail they do it with catastrophic style.

    What was said above. Are they OEM? Your hands don't have to have oil from working on things just natural oils from the skin can cause the hot spot. If I think I've bumped or touched the bulbs I will wipe the bulb with a lint free cloth and 99% Isoproply Alcohol, don't use the more common 70% stuff. Also, don't dry your lint free cloths in the dryer with any kind of fabric softerner, it will leave chemicals on your cloths.

    The bulb was OEM, as far as we can tell. It is branded Phillips rather than Audi, so finding a replacement was not too difficult. $45 - $65 online from various sources, and $178 from Audi.

    Here are some places to pick it up (reference for future people searching AZ):
    Amazon $52:
    https://www.amazon.com/PHILIPS-4300K...s=philips++d3s

    Factoryxenon.com $39+S&H:
    http://factoryxenon.com/shop/new-oem...amp-germany-2/


    This is the OEM bulb. I am somewhat confident that this was OEM as my buddy bought his S4 with only 15K miles on it, so if a bulb failed before then, it would have been replaced with OEM from the dealer under warranty.

    Bumping this post because I just had the same issue!

    2013 S5, 30k miles (best way to estimate bulb usage?) on factory bulbs, never opened the housing or anything. Maybe 20 mins into a drive on the highway (lights were on since the drive started) no big potholes and the bulb out light comes on. I drove for a couple of days with the light out and finally went to replace them today. After wrestling with the housing (no big or jarring movements) I found the same looking bulb.



    $178.00 from the local Audi/VW parts counter , list price on the invoice is $201.14 for a single replacement.
    I was able to shake out most of the loose pieces but think I'd cause more harm than good if I tried to disassemble anything

    Anyone else seen this?

    Faulty bulbs that slipped by quality control, I don't hear too many stories of the HID bulbs shattering too often so it must be very isolated, or like I mentioned they were defective from the start and it was just a matter of time.

    Happened to me about 6 months ago, bought a new set of Phillips Extreme with 150% brightness. Great upgrade with a great color.

    I'm with JamesRS5 above, when they fail they do so catastrophically.

    I hope you didn't pay that dealer price when the same exact Phillips bulbs are $50 online in the links I posted. Also, looks like you have the twin of my car; '13 Misano S5!

    I did pay dealer price :| already bought the replacement before seeing that the old one exploded and before seeing this post. I did save your linked Phillip's for the next time one goes.

    And yes to the twin Misano S5! The best option by far

    ^OMG I want one of those DIY flash lights now.

    Back on topic, I've seen this happen in numerous cars (not just Audis) with factory installed bulbs... including the bulbs in my daily, it seems like one of the guys previously said a to be a little QC slip somewhere in the food chain. Now that being said, for replacement bulbs, I'm a big fan of Morimoto (LINK) bulbs, very high quality, great color options from 4500k to 6500k and a fantastic price point.

    Haha. Funny but not sure if that can compare as ours create a much more cleaner cut-off. And the most they left that light on was about 30 seconds. We are sure that got extremely hot and would have been great to see temperature readings and more info on that flashlight.

    Luckily for our customers our D3S are bright they create cleaner white color temp vs many competitors and many many happy customers running this with only amazing feedback.

    Listing is here - not sure if you are confusing us with a different company:
    http://deautokey.com/product/new-d1s...en-audi-models



    Few reviews:
    I am very sorry I do not have a good picture of the Morimotos my phone into the toliet and lost all my data i'm an idiot for not backing up my pictures learned my lesson the hard way so I looked on google and tried to find the picture which closely represented the Morimotos 6500k bulbs and I couldn't justify taking putting the morimotos back in. I'm sure we all know that replacing the headlight bulbs on the MK7 with the lighting package is a nightmare, you need lift the car up to take off the bumper and grill just to access the bolts that hold it in.
    So on with the review just a couple weeks ago I posted about not being able to see the lines at night when it was raining and was contacted by DeAutoLed to try their 5500k HID's so they sent me out a set of bulbs at a discounted rate to compare the two.

    Morimotos that I found online that closely represented what they looked like at night.

    Morimoto 6500k

    DeAutoLed 5500k

    As you can see the 5500k have more of a pure white in color and it definitely brighter than the Morimotos just driving around on the back roads.

    DeAutoLed

    The packaging on DeAuto compared to the Morimotos is a little better they seem more safely packed as it has foam encasing the bulbs to protect it during shipping. The Morimotos came in a thin cardboard box with no encasing of the bulbs

    Bonus

    DeAutoLED License plate lights I paid full price for these.

    Now I just need to get rid of the ugly yellow cornering lights I should have picked up a set of those so I could have swapped them out during my install.
    So all in all I am very happy with these bulbs. If a blueish color is what you're looking for then go with the Morimoto's but if you're looking for more visibility and a nice pure white color then DeAutoLed is the way to go.

    I opted for the 5500k and am very happy with the outcome. I just put them in 5 min ago so I haven't seen them at night but from looking at oem and this it looks great.

    Here is a picture of the DeAutokey 5500k on the left and oem color on the right. The color matches the drl led better too. The garage wall is gray so the color may be off but it looks pure white with a hint of blue.

    Found this YouTube video (not mine do at your own risk/will) props to the guy who made it.

    This is at startup car is off.


    Here is after 2min and the car is on bulbs now fully warmed up


    You can see the osram on the left is more yellow than the deautokey on the right. As far as brightness goes they are equal if not deautokey is a tad brighter. This is their 5500k color. In person the color is pure white with a hint of blue. Way better than oem imo


    Don't mind the dirty headlight

    So overall I'm very happy with the deautokey set that I bought. And it costs less than the Sylvania osram. Another reason I like them is every other bulb so far has been great and deautokey is an active member on here and backs their product.

    Hope this helps
