The step lights are an LPO, or dealer-installed, accessory with the RPO code 63G, and they cost $200. They were first offered in January of 2021 for any GMC Sierra 1500 with the six-way configurable MultiPro tailgate, which is offered under the Multi-Flex name on the 2021 Chevrolet Silverado and will be standard fitment on a third GM pickup truck – the upcoming all-electric GMC Hummer EV – when it goes on sale in Edition 1 form in the fall of 2021.
In normal times, this would mean that the step lights would be offered on almost every Sierra 1500. As of last month, the MultiPro tailgate has been available as standard on nearly all trim levels (SLE, Elevation, SLT, AT4 and Denali), and is a $595 option for the base Sierra.
The step lights are no longer available to order due to supplier constraints, and it’s unclear at the moment if they will be offered again during the 2021 model year, or even when the 2022 GMC Sierra 1500 arrives, following a mid-cycle enhancement, or MCE. This is expected to happen in the third quarter of 2021.
Other supplier issues have reduced the list of available accessories for the Sierra 1500 as well. The pickup’s selection of assist step options was recently streamlined, while all dealer-installed 22-inch alloy wheels for the Sierra are also unavailable to order for the time being.
