Toyota Camry Headlight Assembly: Common Symptoms and the Usual Culprits
You can install a lot of car modifications like body kits, overhead monitors, and neon lights whenever you want, but one part you have to make sure that always works properly is the headlight assembly of your Toyota Camry. Otherwise, you'll put yourself and other motorists in potential danger. If you already notice that the headlight assembly of your car is acting unusual, then you should immediately do some troubleshooting before it gets worse. Here's a list of some common headlight problems:
Only high-beam lights work
If you have noticed that the headlight indicator on your car's dashboard lit up, but there's no low-beam light coming from the headlights, then what you need to do is to check the dimmer switch because it might be the cause of the problem. You can replace the dimmer switch if it's not connected to combo-switch. However, before you do that, check the lighting relay voltage first using a test light. Remember that it's dangerous to drive on the highway with only high-beam lights on because incoming cars may not be able to see the road clearly, that's why you have to fix the headlight assembly before you head for the road.
Flickering and uneven lights
When the light from your car's headlamp flickers while the vehicle is running, a faulty alternator may be the cause of this problem. Some signs may also include flickering interior dashboard light and dome lights. You can replace the alternator of your car when this happens, but first you need to check the condition of the battery ground because this can also be another cause. You must clean the battery terminals if they are already dirty because dirt buildup may prevent smooth electrical flow.
Headlights stay turned on
It can be really annoying if you've suddenly noticed that the headlight of your Camry won't turn-off because of its glare which can also cause the battery to drain. The most probably culprit of this problem is the headlight relay. You can replace the headlight relay inside the relay panel which is located at the top right-hand side of the battery and primary fuse box. However, you should at least have a copy of your car's relay panel diagram before you perform the replacement because you need to be sure which relay has to be removed.
