Awesome dude! Been looking for videos and content on the 35W HIDs for the 25W headlights, not a lot out there. I plan on purchasing some soon, just gotta fix my left headlight that's aimed at the ground and can't be adjusted because of broken adjustors. Then it's time for new bulbs as a reward lol.

Good luck with the store

 

sorry to hear about that bro but soon it’ll be fixed! Lmk when you’re ready man I gotchu, appreciate the kind words!

 

Good luck on this new business venture. Great to see more upgrades being offered for this platform.

 

I never realized there was an access door for the headlights! I'd have killed for that on my old GLK. That thing ate headlights and I'd have to pull the wheel liner every time... Great video!

 

Given the 35W lights are originally only sold on the active headlights (am I right?), are there no issues with blinding oncoming traffic? This seems like a LOT more light to me....

 

The brightness of the headlight isn't the issue. It's the aim.
Yes, as you're approaching you'll see the light is bright, but if it's properly aligned, it shouldn't blind anyone any more than any other light.

 

Are these bulbs direct replacements for the original 35 watt bulbs in the optional OE headlights? Are these bulbs the same K as the originals?

 

Yes direct replacement, no not same K.
The video attached explains all.
These are 6000K where stock is 4300K (or so)

 

Damn. I am glad I stumbled on this HID bulb thread before I made a mistake and ordered the 35w D3S bulbs for my Q4 Ti sport. I assumed that I had the high performance bulb package; but I do not. My headlight housing does have the D5S stamping and I checked one of the bulbs and it is the stock Philip 25watt bulb.

I just ordered a pair of Mitsubishi OEM(Phillip) D5S 25watt bulbs off Ebay that are selling for $35 dollars each. I am good with the 25watt HID bulb light output; heck I thought that I had the upgraded 35 watt bulbs already. However, I do drive in an urban area that has plenty of street lights everywhere so road lighting is not an issue for me I suppose. The 35watt upgrade would be good for drivers that use less lighted routes at night.


The good news is that the HID bulbs are easy as hell to change on the Q4 model as the bulb door is easy to reach without moving the wheel or anything. Just pop the two clips and reach in the hole to change the bulbs just like in the video.

 

I've driven both and the 35w OE upgrade is very noticeable. I'm very happy that I checked that box when I ordered ours in 17.

 

FWIW: HID bulbs dim over time, so simply replacing old bulbs with new should yield an improvement.
The IIHS found that the 25W headlights produce excessive glare. Putting in a brighter bulb will most likely increase that glare.

I wonder if it is possible to 3D print a replacement for the part that breaks in the headlight adjusters.

 

I wonder what it takes to get to that part to replace it.

 

I wish you much success. I will buy your bulbs this year. I just dropped a ton of money on my car. I need to recover from that first. Might I suggest buying used alfa parts and selling them with your mark up.
