The Isuzu Rodeo cornering light is there to provide extra illumination in the direction of your intended turn or lane change. While it works alongside the turn signals, this light does not blink at all, instead it stays lit up. If the cornering light stops working, you will have one less light to communicate to other drivers with. When this happens to you, follow these guidelines to learn how to diagnose the problem.
The most common cause of cornering light-or any automotive light-failure is a burnt-out bulb. If you have a spare bulb on hand, place it in the socket and see if it turns on. If it does, then the bulb's filament just broke. However, if the bulb still does not light up, then there might be a different problem.
One weird thing about the cornering light is that it is wired into something else separate from the headlight assembly. One of the things it is connected to is the beeping box-the component that makes a sound the moment you insert your keys in the ignition. Unplug this box and reconnect it, then test the cornering light again. This is a common quick-fix for the component, but if it does not work for you then you might have to take a look at the circuit breaker or fuse.
A circuit breaker is a small device designed to break the contact between the power source and the cornering light, just like what a fuse does. Once the contact is broken, the component will not work. A circuit breaker is found anywhere within the lighting system. Look through all the connections of the cornering light to find them. Check your fuse box as well, replacing any blown fuses you find.
Before going ahead to check the rest of the wiring, you might want to take a look at your ignition switch. In many vehicles like the Isuzu Rodeo, the power for the lighting circuits comes from the battery terminal of the ignition switch. Check the connection and the fuse for this component and make the necessary repairs.
