Seeing this is the latest trend on most of the new cars today I wanted to see if I could make my own LED side sills. The inspiration was this side sill from an Audi R8. I drew up the sill design as I wanted it and had my cousin make the name plates for me. They are made from white Perspex with a gloss black vinyl sticker on top (chose these colours to keep with the theme on the car already). I pulled the plastic sill trims out the car, measured and marked the cut-outs and then using a dremel cut and ground the plastic to the desired shape. I neatened the cut out using a file. While cutting I made sure to keep all the clipping points in tact so the sill could still be clipped firmly back into place. I clamped the nameplates and then glued them into place using some high strength adhesive and silicone to seal all the way around the edges. Leaving it overnight to set. To light up the sills I used strips of flexible LEDs, wired them to my interior lights (see my puddle lighting thread for wiring details). Side sill fitted back into the car and end result. I’m really happy with the way they came out, it’s exactly as I had hoped. They are connected to the interior lights so are switched on when unlocking and they go off when the car is locked and ignition switched on. The pictures make them look quite bright but in person they are more subtle.
