Reasons behind Lexus RX300 Headlight Assembly Defects
Despite tough housing and covers, your Lexus Rx300's headlight assembly is still easily susceptible to damage because of its position. Since it is located at the front of your auto, it will generally deteriorate faster than other car parts. It may soon exhibit signs of wear and tear and cause all sorts of headlight problems like flickering and dimming lights. If you suspect that your stock headlight assembly is no longer performing its job properly, you'd better prepare yourself to perform some troubleshooting. Listed below are some problems encountered by the Lexus RX300 headlight assembly and the reasons behind them:
Headlights are not working
If your Lexus RX300's headlights simply won't start up, then your stock parts may have already burnt out. You see, this is a common issue encountered by car owners. Headlight bulbs can easily deteriorate with constant use. If you have recently replaced your bulbs but the headlights are still not working, then you might have an electrical problem. Unfortunately, if this is the case, you might need a little mechanical expertise if you would like to perform a DIY repair. It is best to let an expert perform an electrical repair to avoid aggravating your car's headlight problem.
Do you find your headlights flickering once in a while? It is possible that your stock headlight bulbs are nearing the end of their service lives? There are many reasons for this defect like a loose light bulb. To check, you can simply look if your lighting parts are secured safely in the socket. However, if this is not the issue, then you may indeed have wiring problems. The wires on the assembly may become loose, so they impair the flow of electricity to your headlights.
Dimming or cloudy headlights
Water can enter your headlights if you have worn sealants or defective housings. You see, this condensation buildup can cause lights to dim and impair your vision especially when driving during hazy or rainy weather conditions. Luckily, this is easily diagnosed just by performing a visual inspection.
Malfunctioning lights can also be caused by misaligned parts. Luckily, the lights' position is easily noticeable. You can simply inspect the headlight assembly if it was installed correctly. This misalignment may also be caused by fender benders or rough driving.
