Common Concerns with a Lexus Ls400 Cornering Light
Also known as side marker lights, a Lexus Ls400 cornering lights is built around the corners of your car. These lights serve as complementary accessories to give you a wider lighting range during low-visibility driving conditions. Aside from being an important safety feature of your car, they also compliment the overall look of your vehicle, giving it a more luxurious feel. However, cornering lights are also prone to damage and wear. When they begin to flicker or die out, or if you notice cracks on its lens, it's time to do check the lights out. Here are some of the most common cornering light problems and the factors behind them:
Moisture buildup is an annoying problem most vehicle owners encounter. This happens when water starts to seep through the cornering lights assembly, causing fog to accumulate on the lens. Moisture can also damage the assembly's socket, wires, harness, and bulb. Check the assembly's seals for any signs of cracks or wear. If the seals are intact, remove the entire assembly and use a hair dryer to let hot air blow into its hole. Seal any visible cracks with clear silicone to make it water-tight.
Blinking headlights may sound unusual, but it does happen to some car owners. Basically, when a driver turns on a car's cornering light, the headlights begin to blink intermittently. This problem could be caused by a grounded wire harness or a malfunctioning flasher. Remove the corner light's assembly and check its wires and harness--the problem might lie there. Cut damaged or open wires and replace them with new ones. Don't forget to check the flasher fuse or unit. It may be burnt out already. Remove the faulty flasher and change it with a brand new one.
Lights are always on
Usually, cornering lights are designed to turn off once the steering wheel made its turn. When you notice that the cornering light is still on, it could be caused by a bad signal relay. When this happens, remove the signal relay from its socket. If the cornering light turns off, replace the faulty relay. Also, do not forget to check your car's ECU for busted fuses and worn-out wires.
