5、vised 2014-03 Superseding J1424 NOV2008 Cargo Lamps for Use on Vehicles Under 5443 kg (12 000 lb) GVWR RATIONALE Section 7.1.1.1 was revised to only allow the cargo lamps to be activated when the vehicle is in a non-forward moving gear (park, reverse, neutral) to eliminate the possibility of having
6、white light rearward while a vehicle is moving down a roadway. There was a conflict in the requirements of Section 7.1.1.1 and Section 7.1.1.4. Section 7.1.1.1 allowed three alternative methods of wiring a cargo lamp circuit, only one of which (b), requires the vehicle to be stopped for activation.
7、Section 7.1.1.4, allows the lamp to be activated only when the vehicle is stopped. Section 7.1.1.4 was removed to allow the cargo lamp to be operated when the vehicle is being operated in non-forward moving gears (reverse or neutral). 1. SCOPE This SAE Recommended Practice provides test procedures,
8、performance requirements, and guidelines for cargo lamps intended for use on vehicles under 5443 kg (12000 lb) GVWR. 2.

GUIDELINES 7.1 Installation Guidelines 7.1.1 These guidelines apply to the device as used on the vehicle and
21、 are not a part of the design requirements, performance requirements, or test procedures. 7.1.1.1 The cargo lamp(s) shall be wired in such a manner that it (they) can only be activated, including activation with a switch accessible to the operator from the rear of the vehicle, when the vehicle is in
22、 a non-forward moving gear and either; a. As part of the vehicle dome lamp circuit so that it (they) cannot be activated unless the dome lamp is also activated along with a tell tale device, or b. Independent with a separate on-off switch and a telltale device, with an appropriate label to indicate
23、lamp operation. 7.1.1.2 The cargo lamp(s) shall be mounted on the rear of the vehicle, or the vehicle cab, or in the cargo bed. Multiple lamps may be used. 7.1.1.3 A rear-facing cargo lamp may project only a white light, with the main cone of light projecting both rearward and downward. The main con
24、e of light shall illuminate the road surface or ground immediately rearward of a line parallel to the rear of the vehicle for a distance not greater than 50 feet. The main cone of light may not project to the front or sides of the vehicle. 8. NOTES 8.1 Marginal Indicia A change bar (I) located in th
