SAE INTERNATIONAL J1432 JAN2016 Page 8 of 9 6.5 Design Requirements 6.5.1 If a high-mounted stop lamp or high-mounted turn signal lamp is combined with a clearance lamp or identification lamp, and a replaceable multiple light source is used, the light source retent
36、ion system shall be designed with an indexing means so that the light source is properly indexed to avoid improper orientation of the light source. Removable light source retention systems shall have an indexing feature so that they cannot be reinserted into the lamp housing in a random position, un
37、less the lamp will perform its intended function with random light source orientation. 6.5.2 The effective projected luminous lens area, as defined in SAE J387, of a single lamp shall be at least 50 cm2. 6.6 Installation Requirements The high-mounted stop lamp or high-mounted turn signal lamp shall
38、meet the following requirements as installed on the vehicle. 6.6.1 The high-mounted stop lamp or high-mounted turn signal lamp shall not be obstructed by any part of the vehicle throughout the photometric test pattern, unless the lamp is designed to comply with all photometric requirements of Figure
39、s 1 or 2 with the obstructions considered. 6.6.2 The high-mounted stop lamp or high-mounted turn signal lamp shall be mounted so the horizontal axis is perpendicular to the longitudinal axes of the vehicle with the vehicle unladen. 6.6.3 High mounted stop lamps shall not be installed when a center h
40、igh mounted stop lamp (CHMSL) is installed. 6.6.4 High mounted stop lamps and high mounted turn signal lamps shall be mounted not less than 2800 mm above the road. 6.6.5 All stop lamps must light up simultaneously. 6.6.6 High mounted turn signal lamps and mandatory turn signal lamps on one side of a
41、 vehicle shall be switched on and off by means of one control and shall flash in phase and at the same frequency. 6.6.7 All turn signal lamps on the rear of the vehicle shall be of the same color. 7. GUIDELINES 7.1 Installation Guidelines The following guidelines apply to high-mounted stop lamps or
42、high-mounted turn signal lamps as used on the vehicle and shall not be considered part of the requirements. 7.1.1 Performance of lamps may deteriorate significantly as a result of dirt, grime, snow, and ice accumulation on the optical surfaces. Installation of the device on the vehicle should be con
43、sidered to minimize the effects of these factors. 7.1.2 Where it is expected that the device must perform in extremely severe environments, the user should specify devices specifically designed for such use. Heat buildup in the lamp should be considered in applications where the lamp(s) will be pres
44、sed into the loading dock cushions. 7.1.3 The luminous intensity of the light source may vary with applied voltage. When designing the wiring circuit for the high-mounted stop lamps, or high-mounted turn signal lamps, the wiring should be sized accordingly so that adequate power is provided for the
45、stop lamps to function without degrading the function of the antilock braking system (ABS). SAE INTERNATIONAL J1432 JAN2016 Page 9 of 9 8.
