How to Determine if the Highlander's Brake Light is Broken?
3 Answers
Here is an introduction on how to determine if the Highlander's brake light is broken: 1. Check if the bulb is not lit. You can determine if the brake light is damaged based on whether the light is on or not. 2. Step on the brake pedal to see if the bulb fails to light up. 3. If the brake light bulb is not damaged, check if the fuse is blown. Brake lights are generally installed at the rear of the vehicle, with the main body color being red to enhance the penetration of the light source. This ensures that vehicles behind can easily detect when the vehicle in front is braking, even in low visibility conditions, thereby helping to prevent rear-end collisions.
I've been driving for decades and am very familiar with the brake light issues on the Highlander. The diagnosis is actually quite simple.
Step 1: Find a friend or family member to help. You sit in the car and press the brake pedal while they check if the lights illuminate at the rear. If you have access to another Highlander, compare the brightness with normal operation.
Step 2: Inspect the bulbs yourself. The Highlander's rear light assembly is easy to remove - just open the inner trunk panel, take out the bulb to check if the filament is broken or blackened, and gently wiggle it to see if it's loose.
Step 3: Check the fuse. The Highlander's brake light fuse is usually in the engine compartment fuse box, labeled "STOP". Pull it out to inspect for breaks, and try replacing it.
Step 4: If the lights still don't work, there might be wiring damage or switch issues. In this case, it's best to visit a dealership for professional testing.
I recommend regularly checking your lights during routine maintenance to avoid accidents and fines caused by faulty brake lights.
I often enjoy DIY repairs on my own car, and diagnosing a Highlander's brake light issue isn't too difficult. First, set your phone to video mode and place it at the rear of the car. Get inside, press the brake pedal, and record a clip to check if the lights illuminate during playback. If they're out, lift the trunk lid, locate the brake light bulb, unscrew it, and inspect—replace it if burnt out. You can find an identical bulb at the supermarket for just a few bucks. Alternatively, check the fuse box: under the hood, there's a black box; open it, refer to the diagram to identify the brake circuit fuse, and replace if blown. Sometimes loose wiring connections are the culprit—try tightening the plugs by hand. I always keep a toolkit handy for such replacements—it's simple and cost-effective. However, if the problem persists, don't delay; consult a mechanic to avoid compromising nighttime driving safety.
