w/e ill just answer it. For 75 bucks you can buy an extra set of tail lights and night shade them. Looks the same for 20% of the cost. I would buy an extra set only if you mess up which is actually highly unlikely. Then after yer done just sell your old OEM ones and youll actually end up only spending 30 in total which is less than 10% of the cost.
they have a sticky on how to nightshade
(i like the clear tail lights on my lapis blue 6 though which im stickin with)
