SaleAllDay365 via eBay offers this Motion-Activated LED Toilet Light for $2.49 with free shipping. That's slightly below our mention from three weeks ago and the lowest price we've seen. (It's the best deal now by $3, excluding other eBay vendors.) It cycles randomly through eight colors (15 seconds per color, 120 seconds per total cycle) and requires three AAA batteries (not included).

Note: This item ships from mainland China and may require two to seven weeks for delivery.
