A fill level indicator assembly for an agricultural material bin such as a seed dispensing hopper. The assembly includes an elongate sighting member which provides a water impermeable cover over an indicator opening in the bin cover and has a transparent portion providing visual access to the interior of the sighting member. An indicator rod extends through the indicator opening and has a distinctive marking located near one end. The opposite end of the indicator member has a foot which engages the agricultural material within the bin. Gravity causes the indicator member to lower as the quantity of agricultural material within the bin is depleted. As the indicator member lowers, the distinctive marking within the sighting member is also lowered thereby providing a visual indication of the quantity of material remaining in the bin.
