These are my most basic and cheapest tail lights. they are not plug and play, you will need to cut your wires to install them. they do come with gaskets. only available with square backup light. Wires coming out the back will be 6 inches long and come with diagram of how to install. Update, i do offer plug and play for an additional 25 dollars on these lights. also, in the picture above, there are 3 strips of brake leds but i found that i can fit 5 strips in there for a brighter brake light.
