Several possibilities; faulty oil pressure switch (located near the engine oil filter), faulty / corroded wiring or connection at the pressure switch, faulty oil light (loose connection).
Check the many on-line auto parts sources, such as; www.partstrain.com, www.partsgeek.com, www.carpartswarehouse.com, or www.rockauto.com for the replacement parts.
For example, they (RockAuto) list the oil pressure switch from around $7.60 for your vehicle. Before replacing any parts - first check the switch and wiring conditions.

If this is dirty oil change, then if problem persists do as Jimm has recommended.

The other possibility is low oil pressure. the oil light comes on when there is less than 5 PSI of
oil pressure. If pressure switch doesn't fix it then have the pressure checked with a positive
gauge ( mechanical gauge ).
