Audi A4 LED Interior Lighting B6/B7 – DIY & Pics

This is the second post in the series of my interior makeover – stay tuned for some more changes and be sure to follow me on Twitter for some teasers!

LED Interior Lights on my Audi A4

Given how my exterior lighting has went from halogen to LED, I thought it was time my interior kept up. This was a super easy mod that only cost about $100 and took but 1-2 hours total at a leisurely pace.

  • Skill Level: Beginner
  • Time Estimate: 1-2 hours max
  • Tools Needed: Flat head screw driver, common sense

I replaced all of the lights except the vanity mirrors as I didn’t think they were worth it, nor did I want to look like a smurf ;) For each bulb, I bought the Cool White color, which gives off a slight blue tint to it. These pictures were taken with a simple Casio point-n-click camera on high exposure with no tri-pod, so the color isn’t perfect, but close enough anyway. I’d say in real life they’re a little less blue.

Rather than re-write a perfectly good DIY, I’ll suggest for the step by step instructions on which bulbs to replace and how, check out this thread on Audizine. You’ll note it is for a B6 (2001.5-2005.5) but the lighting is exactly the same for a b7 (2005.5-2008). I didn’t remove the fuses prior to starting, although if you wanted to be extra cautious you could, otherwise I followed those instructions to the T. I also purchased my bulbs through superbrightleds.com and was very pleased with the experience, so I’d recommend you check them out.

What you’ll need is (note: all bulbs should be 12 volt):

  • 11x 194 LED Wedge bulbs (4 Footwell, 4 puddle lights, 1 glove box, 2 trunk): link (just get 3 packages of 4 and you’ll have one extra just in case)
  • 4x BA9 LED Bayonet bulbs (front and rear reading lights): link
  • 2x 42mm Festoon bulbs (front dome lights): link
  • 2x 36mm Festoon bulbs (vanity mirrors, which I chose not to do): link

Really, there isn’t much to this. Pull the old bulb out, put the new one in.

And here are more pictures of the final result!

The dome lights – they’re REALLY bright, in a good way:

I love how these LEDs illuminate my new Platinum Silver Recaro Seats! The next post in the interior makeover series will include more info on the seat swap process, so stay tuned for that.

And a final shot, just because I love how it came out so much:

    Thats a good question. I don’t think that is possible through VAG-COM, but if you can locate the sensor that is used to tell if the door is open or closed, then just relocate the sensor so it thinks the door is always open, that might work…you need to be careful it still turns off when the car is turned off, otherwise you’ll drain your battery though. Let me know if you find a way to do this, that’d be cool…

    I thought it would be simple/common (rewire all the footwell lights into whichever fuse gets turned on when you turn on the night time lights)… Guess not! I’ll let you know if I figure something out.

    Thanx i ordered all the lights yesterday well see what happens when they get here.. Also, did u say i should dis connect the battery? Or just pull the fuses. Then instal and plug them back in one by one to see if it works?

    damn my shits all messed up hahahahaah.. I started the lights i got the ones for the doors, glovebox etc… needless to say these guys can be tricky and i def have a couple gremlins in my car now hahaa. They look great. For the couple mins they were on. I cant get the footwells to stay on i dont get it! At first i just closed the doors for a couple mins and then maybe it reset cus they came on and looked great. Then i started the rear and as soon as i unpugged that one theyall went out!!!!!!!!! It was on for a sec but then it went out and even closing the door for a couple mins didnt work and it never came back on i dont get it. And now all four front and rears are out this sucks. Any suggestions? Maybe bad fuses? I could have swore the footwells in the front were out periodically with the old bulbs so maybe thats it.

The glove box is but thats it i dont get this Hey nick we have the exact same car did u have any problems?
