This was my first (and only, so far) mod on my 2018 Civic sedan. These are easily available on ebay and run anywhere from $25. to $50. I paid about $32. and they were a breeze to install (about 20 minutes for both sides). I followed one of many video instructions available on Youtube.

I wanted to replace the garish orange factory side marker lenses with the 'smoked' lenses which complement my Modern Grey Metallic paint - the result was pleasing. Just a subtle change but one that many 10th Gen Civic owners have done, at least going by all the instructional videos on Youtube! Recommended for those who don't care for the factory orange lenses. Clear lenses are also available for the same price range.
