The light indicates a charging system problem, or a low battery.
Is your battery the original one? If so, you are lucky to have had it this long.
Put a volt meter on the battery with the ignition off. It should be around 12.6 volts if it's been off for a while.
Put a volt meter on the battery with the engine running. It should be around 14 volts.
Then, have a load test done on the battery.
