The installation seemed easy at first, and I did watch videos online and read tips and the instructions but it didnt work for one of the taillights because when I was trying to heat shrink it getting it all lined up it tore and ripped, which made me frustrated and couldnt keep the other taillight that i had already installed. Ended up discarding the taillight tint, but the headlight was a breeze. Got it installed in less than 10 min. The curvy taillight of my Civic made it difficult to install because the tint wasn’t quite forming along and was stubborn to stay in position during installation. I would recommend this product to my friends, but professional installation would have made this product the best. I love DIYs; this was my first time installing tint and it takes patience to truly achieve a wonderful results.
