This SAE Recommended Practice provides test procedures, performance requirements, and guidelines for cargo lamps intended for use on vehicles under 5443 kg (12000 lb) GVWR.
Section 22.214.171.124 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 white light rearward while a vehicle is moving down a roadway.
There was a conflict in the requirements of Section 126.96.36.199 and Section 188.8.131.52. Section 184.108.40.206 allowed three alternative methods of wiring a cargo lamp circuit, only one of which (b), requires the vehicle to be stopped for activation. Section 220.127.116.11, allows the lamp to be activated only when the vehicle is stopped.
Section 18.104.22.168 was removed to allow the cargo lamp to be operated when the vehicle is being operated in non-forward moving gears (reverse or neutral).
