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!
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:
Hope this helps!

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.

Hey i changed my b7 s4 interior lights with their kit from ECS and it was definitely very difficult to properly align the wedge type bulbs, they even feel loose once they are in. Not sure if they are going to fall out but anyways. Every time i open my door the light will give a flicker initially for a sec, but stays on after like it supposed to. I noticed that if the key is not in the ignition you cannot turn on the interior lights manually. They go on very very dim, can barely even notice them on. Have you experienced this and do you have a suggestion?

I don’t have the ECS kit, and haven’t had this problem with my bulbs. I like ECS as a vendor, but their LED kits seem to be very overpriced for what you getting (over double the cost of what the bulbs retail for when purchased individually) and the reviews on their kit quality is mixed. I haven’t heard that exact complaint before, but yeah, I haven’t heard many people raving about the kits either. It sounds like maybe the built in resistors they use are too strong? If the car needs to be running for the bulbs to be bright, that must mean they’re drawing a lot of current which is not how the LEDs should work normally (LEDs draw less current, not more, than OEM) so there must be some sort of resistor at play. Either that, or you’ve got a bad connection from the LED to the metal in the car, but I’m sure you’ve checked that already?

Ya I’ve checked all the connections. ECS said that’s normal since their LED’s and they’ll give me a refund but its too much of a hassle switching them all again lol. They still look good and there all the same bright white. Heard some LED’s are not the same shade of white.

Hi Nick,
The BA9 bayonets you have links to are too long to work. They don’t allow you to tuck the rear reading light unit back into the headliner.
Just a heads up!
at 10:45 PM
That’s strange. I remember it being a tight fit but I remember being able to get it to work. I updated the link to a shorter bulb just in case. Thanks for the heads up!
at 11:18 AM
Ya, I wound up squeezing them in but the headliner was definitely giving the ends of the bulbs some business. I was trippin I might break something.
Thanks for the writeup! I felt the most difficult bulbs were getting the ones to stay put in the flood housings. I had to re-do a couple after repeated door slamming.
