The Common Culprits of Faulty Volvo 850 Corner Lights
The corner lights of your Volvo 850 illuminate the areas on the sides of your car so you could see the road clearer, and you can maneuver your car better. In spite of that, the corner lights are prone to dirt and grime; and through constant use, they will eventually show signs of malfunction. If you already notice that the corner lights of you vehicle is starting to become problematic, you should perform some troubleshooting. Read on to know some of the common problems you could probably encounter.
Malfunctioning corner lights
When your Volvo 850 corner lights are malfunctioning, what you need to do is to check their voltage using a multimeter. If the lights are in good condition, the multimeter should read 12 volts. Otherwise, the bulbs of the corner lights are already busted and you need to replace them immediately. However, if you saw the reading go up to 12 volts, but there was no light from the bulbs when you switched them from the car's dashboard, then the wires or connectors may be loose or disconnected. You have to reattach the wires firmly before you switch on the corner lights again.
Discolored corner light
Through time, the corner lights of your car will turn yellow because of aging. Aside from that, scratches and dirt that have built up on the surface of the corner lights leave the lights looking dull and unattractive. You can try and polish them using a microfiber cloth and a polishing compound if the discoloration is not severe. However, if the corner light has totally turned dark and yellow, then you might need to sand the corner lights already. Just remember not to use heavy sandpaper because it may cause deep scratches instead of removing them.
Corner light not bright enough
If you notice that your car's corner light is not bright enough, you have to take a closer look at it because dirt on its surface or condensation inside may have caused the light to dim. To check if it's dirt that's caused it, you can simply wipe the light's surface and see if it brightens up. You can also check if there's condensation inside the lights by simply looking for signs of moisture. However, if none of those two worked, then you need to test the bulb if it's starting to wear down and might need a replacement soon.
