For integral or separate Turn Signals! Each light is split 40-20 so that the LEDโs can be wired for either type of turn signal. 60 Super Bright Red LED strips inside aluminum housings. 1/4โณ thick build-in, flush mounted red acrylic lenses with prismatic diffusers โ can be fit into slightly curved fenders, roll pans and pickup bed corners up to 1/4โณ for a seamless look (the acrylic lenses cannot be bent). Taillights have dual intensity for taillights and turn-brake lights. Need only 1โณ of clearance space behind the mounting surface. Weld-in or glass-in studs for mounting are included. Quality instructions. Lenses are only 1/2โณ wide by 15-1/4โณ long! Note that these are build-in kits requiring paint and body skills.
