Lexus LS400 Side Marker Lights
Common Issues with the Lexus LS 400 Side Marker Lights
Designed to make your car more visible during low-lighting conditions, the Lexus LS 400 side marker lights help other drivers know your car's length and width. Since your car is a bit bigger than the usual sedan, these lights can be found at the front and rear of your vehicle. Sometimes, side marker lights are connected or relayed to a car's turn signals to add more visibility. This helps other drivers know when the car's changing lanes. But when you notice that your side marker lights are malfunctioning, it's time to check them out. Here are some problems encountered with the Lexus LS 400 side marker lights:
When you notice that your side marker lights aren't lighting up, this could be caused by a busted fuse. This is caused by excessive current flow due to faulty wiring or relays. If this happens, the first thing you need to do is to identify the blown fuse. Open the fuse box to check the fuses. Once you identify the busted fuse, remove it immediately. Before you install the new fuse, make sure that it has the same amp rating as the old one. Attach the new fuse and test your side marker lights. If you're having trouble finding the side marker fuse, consult your vehicle owner's manual for more details.
Bulbs are prone to burning out as time goes by. This could be caused by poor sealing, overloading, gas or filament evaporation, and prolonged use. Fortunately, replacing burnt-out bulbs is relatively easy and cheap. Open the side marker lights and remove the bulb from its socket. Secure the new bulb on the socket properly and close the side marker's assembly. Test if the new bulb works.
Loose wirings or relays
If your side marker lights are behaving intermittently, this could be caused by loose or faulty wirings. Inspect the wirings connected to them and check for loose or worn-out wires. Don't forget to check the relays too; they might require a little bit of attention. Secure loose wires and relays and replace all the worn-out ones immediately.
