Shopping List: Tools & Parts You’ll Need
Before diving into the installation, make sure you’ve got everything ready. Here’s your complete shopping list:
Trim Tool Set
A good trim tool set (under £10 on eBay) helps you remove door cards safely without damaging clips or scratching panels.
Puddle Lights (OEM Rings or Alternatives)

Many enthusiasts prefer OEM lights (our store provides £29.99 with same qualtiy and warranty), which give a clean, factory-fitted look.
Heat Shrink Tube
This is essential for covering metal connectors. It’s a bit fiddly, but normal electrical tape can work if needed.
Tesa Tape (Optional)
For extra durability, wrap the heat shrink with Tesa tape to protect wiring from wear and tear.

-
Double-check that both screws are removed before attempting to pry the card.

Step-by-Step Guide to Fitting Audi TT Puddle Lights
Removing the Door Cards Safely
Unscrewing Hidden Screws
Ensure you’ve removed both screws (often hidden behind trim) before applying pressure with the trim tool.
Using the Trim Tool on Clips
Work slowly around the edges. Most clips are sturdy, but the aluminium clip in the top corner bends easily. Align this one first when refitting.
Disconnecting the Wiring Module
Once loose, carefully disconnect the blue wiring module at the bottom corner. Don’t tug—it’s delicate.
Adding the New Wires
Handling the Wiring Module
This step is the trickiest. You’ll need to separate the module and insert two new wires into the correct slots without damaging existing ones.
Dealing with Metal Connectors
Use a small screwdriver to press down the tang on the connector; pulling directly won’t work.
Cutting the Hole for Puddle Lights
Correct Measurements and Adjustments
The Rocketwires instructions may be slightly off. Cut the hole a bit smaller, then file until the light fits snugly.
Refitting the Door Card
Aligning Clips Properly
Line up the aluminium clip first, then press the rest into place. If you break one, don’t panic—the fit will still be solid.
Common Mistakes and Tips to Avoid Them
-
Don’t cut the hole too large—measure twice, cut once.
-
Avoid pulling wires too hard; they’re thin and fragile.
-
Take your time with the wiring module—it’s the hardest part.
-
Always align the aluminium clip first during reinstallation.
How the Finished Puddle Lights Look

Once installed, the Audi rings puddle lights look fantastic. However, note that the projection is clearer when the door is fully opened. Some owners wish they could shift the hole placement further out, but clearance may not allow it.
