Indications of a Defective Ford Ranger Third Brake Light
Your brake lights are built to warn other drivers when you are about to stop or slow down. A third brake light supplements your two rear brake lights, so trailing drivers will be able to react faster than usual. Over time, these brake lights may exhibit signs of damage or may not even work at all. There are some instances that only the third brake light will malfunction. If you suspect your third brake light to be already defective, then you had better perform some troubleshooting. Here are a few indications of a defective Ford Ranger third brake light and the reasons behind them.
Only the third brake light is not working
The most probable reason behind a third brake light not working is a burnt out bulb. The part may have simply exceeded its service life. To check for a burnt out bulb, simply buy a new one and test if it solves the problem. Make sure you wear gloves to avoid causing the bulbs' premature wear. If the bulbs are fine, then there may be a problem with the fuse or wirings. To test the fuse, use a fuse testing device, which should be available in most auto supply stores. Look for signs of a broken filament or a burnt fuse. In other cases, the wirings are at fault. They may have simply corroded and you'll need to find a replacement.
Brake light on the dash stays lit
In some cases, the brake light on the dash stays lit even if the switch is turned off. A simple fix to this brake light problem is by restoring the brake fluid's level. You see, if you have a low brake fluid level, the brake light will stay on. You can easily locate the brake fluid container with your service manual. It is commonly situated near the driver's side rear firewall. Sometimes the switch may have simply malfunctioned, so you may also want to check that.
Cloudy third brake light
A cloudy brake light should not be a problem if the automotive lights are constantly monitored for cracks. You see, these cracks can cause moisture to creep in and lead to cloudy lights. This can be dangerous as it lessens the lighting power of the lights.
