Gigabyte offers two RGB dummy modules for free with its AORUS RGB DDR4

We've already covered this product when it was revealed at Computex, but now Gigabyte is running ads for its AORUS RGB Memory. These sticks run at 3200MHz with 16-18-18-38 timings and feature an aluminium heatspreader with integrated RGB LEDs.

Interestingly, these kits are offered in 16GB (2x 8GB) editions but Gigabyte offers them with an extra two RGB-infused modules for free. These two dummy modules do not contain DRAM chips but have the same heatspreader and RGB LEDs, to create the illusion of a full DRAM bank on your motherboard. Unfortunately, we don't know the pricing so we can't judge how "free" these RGB modules really are.
