Toyota Camry Headlights: Some Issues that Prevent the Lights from Working
Your Toyota Camry headlights are inarguably one of the most used parts on your car. Made to cast illumination on your way when driving at night, your car's headlights are constantly exposed to varying conditions that affect their performance. Sometimes, the headlights may have manufacturing issues that need to be resolved. Since driving without the headlights on is both a risk and an offense, it pays to know the things that might affect your headlights' performance.
One of the headlights is not functioning.
If only one of the lights is not working, you might be having a bulb issue. This is the easiest issue to troubleshoot since it requires only a visual inspection of the bulbs. If the bulb on the affected headlight has turned dark, remove it and replace it with a new one.
Headlights flicker on and off.
Intermittent power on the headlights can be due to any of the following: blown fuse, short circuit, and relay problem. Most headlights are equipped with automatically resetting circuit breakers. Sometimes, these circuit breakers trip and cause the headlights to turn off. The lights would only come back on once the breakers are reset. Inspect the circuit breakers and replace any wire that might have short-circuited. If the circuit breakers are clear, look into the fuse box to see if the one of the fuses have blown. Replace it with a new one with the same amperage and test the lights. However, if you see no problem on either the circuit breaker or the fuse, you need to check on the relay. There might be a loose connection or bad wiring that connects the relay to the computer.
Headlights don't appear bright as usual.
Dimming of the headlights usually happens when other car systems are in use. The electrical power tug-of-war is what's causing the headlights to appear muted. Turn off the other systems in your vehicle and see if the headlights' brightness has improved. If not, your car's battery or alternator may be weak and in need of replacement. If the bulbs and other headlight parts are working fine, but the light remains dim, you need to inspect the headlight covers for signs of fogging. The hazy covers may have diffused the lights' brightness. Clean the moisture and dirt buildup on the lenses and see if it makes any difference on the intensity of the lights.
