Notes: Light Sources are required to illuminate the Lumbridge Caves, and various other locations in RuneScape. You can make an oil lamp at level 12 crafting by making molten glass, using a glass blowing pipe on it and using the lamp with some lamp oil. Making this gives 25 crafting experience. This requires level 12 firemaking to light. Remember not to light a candle in your inventory with an oil lamp or it will explode!
