Do you know what are the design and development settings for car taillights (2)?

Rear position lights:

a. Equipped: Required; Quantity: 2.

b. Installation position: Lateral: the distance between the outer edge of the apparent surface in the direction of the reference axis farthest from the longitudinal symmetry plane of the vehicle and the end face of the outer edge of the vehicle should not be greater than 400mm; Height: the height from the ground should not be less than 350mm, not greater than 1500mm.

c. Geometric visibility: Horizontal direction angle: β is 45° inward and 80° outward; Vertical direction angle: α is 15° on the horizontal plane and 15° below. To be visible, the unobstructed apparent surface of the lamp must be no less than 12.5cm2.

d. Indicator: must be equipped with a turn-on indicator, and should be completed by the indicator of the front position light.

Brake Lights:

a. Equipped with: S1 or S2 must; Quantity: 2 pieces.

b. Installation position: Transverse (width): the distance between the outer edge of the apparent surface in the direction of the reference axis farthest from the longitudinal symmetry plane of the vehicle and the end face of the outer edge of the vehicle should not be greater than 400mm; Height: the height above the ground should not be less than 350mm , not more than 1500mm.

c. Geometric visibility: Horizontal direction angle: β is 45° inward and outward; vertical direction angle: α is 15° above and below the horizontal plane.

d. Indicator: optional; if equipped, it should be a non-flickering alarm working indicator light, and the indicator light will be on when the brake light fails.
