Red firelighters are a possible reward from Treasure Trails. Their use are mainly cosmetic, changing a fire's colour to red. In order to do so, use them with regular logs to turn them into red logs, then light the logs with a tinderbox.
In addition, players can use 250 red firelighters on a Phoenix that has been recoloured to revert it back to its original colour.
