As opposed to the redundant turn signal lenses fitted to 911s bound for the USA, European-market cars instead made do with only one forward-facing turn signal lens on each side, opting to fill the empty space with rubber trim similar to the front rub strip. A popular upgrade is to replace the side lens with this rubber insert. Thankfully, new replacements are available from Porsche. Simply remove your side market light and replace it with new rubber trim for each side. The right side is also available as part number ES2986776.
