Your Toyota headlights, brake lights and tail lights should be in perfect condition. This is because they play a crucial role in ensuring that you, your family, and other motorists arrive alive. Bad light bulbs and broken lights put everyone at risk. In addition, they can earn you a ticket from the authorities. Carry out regular checks on your Toyota Prius to ensure that light bulbs are functioning properly. If you need a replacement, shop only for OEM parts and be wary of aftermarket imitations.

While some may be cheaper, they’re likely to burn out quickly and do more harm than good.

Toyota Prius Headlights

Headlight lenses are typically made of polycarbonate plastic which protects the bulb from damage during impacts. Because of this, headlights require replacement when their lens is damaged. Toyota Prius headlights should be replaced because of haze or cracks that appear over time. You can easily check for this because you’ll notice that light isn’t passing through the headlight’s glass correctly. The easiest way to fix this is to replace your headlight assembly with an OEM one. Since these parts are expensive, you might want to consider getting a third-party part instead. However, avoid aftermarket units if possible (they’re poorly made and don’t fit properly).

Toyota Prius Brake Lights and Tail Lights

Brake lights, tail lights, and license plate lamps are lit almost daily. They’re exposed to extreme temperatures which can cause internal components to corrode or malfunction. These components (e.g., resistor) may be cheap but you still require OEM replacements because they ensure that your brakes and turn signals work properly. Plus, low brake light output is dangerous for everyone in the car because it could affect the stopping ability of the vehicle.

Toyota Prius Bulbs: Light Emitting Diode (LED) vs Incandescent Bulb/Halogen Bulb Headlights – Toyota Prius headlights use halogen bulbs when you first buy it. However, LED headlights are becoming common in high-end cars due to their low power consumption and long lifespan. They can turn on instantly (unlike HIDs), which is great for turns during the night. The only downside of using LED headlights is that they don’t provide enough UV protection, so you’ll need to use these bulbs with additional lenses or shields.

HID Bulbs – These emit more light than halogen ones, but they’re also slightly dimmer than LEDs. When shopping for replacements (e.g., HID Xenon kit) make sure you get one that matches your car’s original type; otherwise, the wrong bulb won’t fit into its housing or connect properly to electrical components (this means you won’t get maximum light output).

Halogen Bulb – Halogen bulbs were the first type of headlight and they’re still common today. They provide better visibility at night, but consume more power than LEDs or HIDs. Since these bulbs emit less UV rays than other types, you don’t need extra lenses but they do require longer to heat up (instant-on lights such as LEDs can cause temporary blindness if looked directly into for a short period).

Toyota Prius Lights: The Different Types of Headlights and Bulbs – Table 1: When shopping for replacement headlights, you’ll encounter different types that include: High/Low Beam (both replace the same components), Fog Lightsrequire separate parts since their housings are separate, and Demon Eyeswhich allow you to customize your car. If you go shopping for a new pair of headlights or want to improve your current lenses with a retrofit kit, it’s important that you know the difference between halogen bulbs, HID xenon lights, LED lights, and demon eyes .

Toyota Prius Headlights: Halogen Bulbs vs LED vs HID Xenon – The interior components of your headlight can be divided into low-beam and high-beam units. On one hand, the low beam unit includes a bulb as well as its housing (lens). Manufacturers often use light sources such as LEDs or halogen ones in this part because they’re cheaper than HIDs (low-beam headlight bulbs are always halogen). On the other hand, high-beam headlamps include just one bulb and housing (i.e., they don’t contain individual low-beam ones). Due to this reason, manufacturers often use HID Xenon lights or LEDs in these units because they emit more light than halogen bulbs.

Toyota Prius Corner Light Lenses – As mentioned earlier , you should replace your headlight lenses if they’re broken or cloudy. However, many people overlook the fact that corner lights will show signs of deterioration as well. You’ll know when they do because you’ll notice that light won’t pass through properly (usually due to cracks on corner light housings) or most of the time straightaway
