Updated in 2020 to recommend new products and add better pictures now that I own yet another B7…for what it’s worth I have now done this exact mod on an A4, S4, and RS4 with the same results, highly recommended!
If you’re looking to upgrade your interior lighting in your B6 or B7 (8E chassis) Audi A4, S4, or RS4, look no further.
While many companies sell special kits for your car that they then markup for 2-3X the cost, you can buy the bulbs individually at a much lower cost to get the same outcome.
Best of all, this is a super easy mod that only cost about $40 and takes under an hour at a leisurely pace.
- Skill Level: Beginner
- Time Estimate: 1 hour max
- Tools Needed: Flat head screw driver, common sense
B6/B7 LED Interior Kits – Where & What to Buy:
You can buy all of the bulbs seperately as I did in the past, but these days LEDs have gotten super cheap and easy to find so many companies offer “kits” with all of the bulbs you need at a fraction of the price of buying the bulbs seperately.
This kit is only $25 and appears to come with everything you’ll need; however, they don’t give you details on what bulbs are included and there are some complaints about light output – therefore I prefer to buy bulbs individually using the links below, but I’m including this if you’d prefer to go the easier route:
If you want to buy the bulbs separately, or want to piece this together using bulbs you already have as many of these are common sizes, here is what you’ll need…note the cost works out to about the same as above, but you get some extra bulbs and a little more control over what you get.
- 11x 194 LED Wedge bulbs (4 Footwell, 4 puddle lights, 1 glove box, 2 trunk) – $10 for a pack of 12 on Amazon: https://amzn.to/2R33MK1
- 4x BA9 LED Bayonet bulbs (front and rear reading lights): $9 for a 4 pack: https://amzn.to/32YaKWc
- 2x 42mm Festoon bulbs (front dome lights): $4.19 for two – https://amzn.to/32YaMgM
- 2x 36mm Festoon bulbs (vanity mirrors, which I chose not to do): https://amzn.to/2ZcX097
No matter where you get your LEDs from, make sure that the light output faces downward so that it illuminates in the correct direction (you do not need 365 degree output!).
Likewise, CANBUS is not necessary for interior LEDs – none of these bulbs throw a code or are monitored by the computer, so “normal” LED bulbs are fine. CANBUS bulbs will still work if you have them on hand; however, they cost more so if you’re ordering bulbs for this project you can save the money.
How to Install Interior LEDs
Really, there isn’t much to this on a basic level – pull the old bulb out, put the new one in…if it doesn’t light up, then take the bulb out and flip it, as LEDs are polarity sensitive.
Start with the overhead dome lights as they are easiest to do. Pry the entire assembly off using a flat head screwdriver as pictured below.
The 42mm festoons go in the larger “dome light” opening as pictured above, then the BA9s go in the reading lights on the left/ride side accordingly which you can expose by popping off the black (or silver) cover.
Simply snap the covers back on then reinstall the overhead light and that’s a wrap for the front…the rear is the same only easier since there are only two BA9s needed.
The footwell lights as well as the puddle lights in the door also come off using a flathead screwdriver, but are harder to get to since you have to crawl on the ground…
Pry the plastic holders out using a flathead screwdriver – one side releases easier than the other, so if you feel like you need to use too much force try prying from the other angle. Once it pops out you can replace the bulb then snap it back into place. The same process is true for the footwell lighting under the dashboard and underneath the front seats.
Other than that, it’s a pretty simple process going one bulb/housing at a time.
Be sure to take your time and be sure to check the polarity before reinstalling the housing to save yourself headache in case it doesn’t light up when you’re done!
LED Interior Pictures
The finished product of about $25 in parts and an hour of work is well worth it!
While pretty much all new cars now come with LEDs due to both superior light output and longer life, in older cars like these it really spruces up the interior.
I also loved how these LEDs illuminate my new Platinum Silver Recaro seats in my past A4 and S4 cars.
And a final shot, just because I love how it came out so much:
This is a mod I’ve done on every vehicle I’ve owned, and plan to keep doing until I buy cars that start to have them pre-installed. I can think of very few if any mods that have a better bang for the buck in terms of both form and function, so it’s no wonder why nearly every OEM on the planet has switched to LED bulbs in their new model line-up.
