Your vehicle's trunk or cargo light illuminates your trunk or truck bed area when activated. Unlike most lights on your vehicle, if your cargo light bulb burns out, it's not an urgent safety concern. But if your cargo light burns out, you may not be able to see when loading or unloading items from your vehicle in the dark. Since this bulb is only on for short times, it may not often go bad. Check the cargo light bulb before replacing it to make sure that a switch or the bulb socket may not be to blame. When you need a replacement cargo light bulb, check out the selection of bulbs at O'Reilly Auto Parts. We have interior and exterior lights of all kinds for your car, truck or SUV.
