We get asked this pretty often: "Do SUV headlights yellow faster than regular car headlights?" Short answer: not necessarily. But there are definitely factors that make some vehicles suffer more than others. And yeah, SUVs end up in the mix more often.
It's not the vehicle type, it's the exposed surface area
The polycarbonate used in headlights is the same whether we're talking about a Civic or a RAV4. The difference is that SUVs usually have bigger headlights with a larger plastic surface area. More surface exposed to UV means more potential for oxidation.
SUVs also tend to have headlights positioned higher up. Seems like no big deal, but a headlight that sits higher gets hit by splashes and debris differently than a low-mounted sedan headlight. It's also more exposed to head-on wind, which carries abrasive sand and dust.
The real factors that matter
What determines how fast your headlights yellow isn't really the vehicle type. It's more about where and how you park your car. An SUV parked in a garage will keep its headlights clear way longer than a small sedan parked on the street in direct sunlight.
Where you park matters too. If your car's front end faces south for 8 hours a day, your headlights are getting maximum UV rays. Park your car facing the other way and your headlights will last longer. That simple.
Mileage plays a role as well. The more you drive, the more salt spray, sand, and road debris your headlights take. Someone commuting Montreal to Quebec four times a week is going to wear out their headlights much faster than someone who just drives to the grocery store.
The models that struggle most in Quebec
Without calling out specific brands, we've noticed that vehicles with large, flat headlight surfaces and minimal curves tend to yellow faster. Headlight designs that are more rounded or angular usually hold up better, probably because water and debris slide off the surface more easily.
Vehicles from 2015-2020 show up pretty regularly in our restoration appointments. That's the window where factory protection wears completely and yellowing becomes noticeable. If your car falls in that range, check out our article on the 5 signs it's time to restore your headlights.
The solution is the same for everyone
Whether you've got an SUV, sedan, pickup, or compact car, the restoration process works the same way. Sanding, polishing, ceramic protection. The process gets tailored to your headlights' specific condition, not the type of vehicle. We walk through the steps in our article about our mobile headlight restoration service.
