For some users, Corsair keyboard lighting can completely stop working. However, you might be able to fix a Corsair keyboard’s lights with these resolutions.

First, check if you need to update your Corsair keyboard’s driver. The easiest way to do that is to run a driver updater software scan.

A driver updater utility will show if your Corsair keyboard’s driver is outdated. Up next, you can install the latest driver for your keyboard with the driver updater software.
