Thanks.. I’m a bit leary about the it as well. I let the installer do what he wanted but I will flatten and drop it down to a 10. Right now just enjoying the sound.
How do we know which side markers fit? I don't want to buy from the above seller as he is charging $80 shipping to Canada. I assume these would fit: http://www.ebay.ca/itm/For-16-Up-Honda-Civic-CRYSTAL-SMOKE-Bumper-Reflector-Side-Marker-Lights-Lamps/322359984639 Getting parts here sucks.
I helped a few people from canada - I bought the side markers and then sent to them stating the were non-operable gifts.
Guys, don't spend $80. These fit, can confirm. https://www.amazon.com/gp/product/B073X69N7D/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1 Edit: Pics added. I'm on the right. Shout out to @BamaDave on the left.
