Headlights don't need complicated maintenance, but they shouldn't be forgotten for years either. In Quebec, with road salt, temperature swings, and long months of driving in damp conditions, waiting until they're completely cloudy isn't your best move.
The right schedule isn't the same for everyone, but a few simple guideposts keep you from getting caught off guard.
Spring is a good time to check your headlights
After winter, your headlights have usually taken a beating from a full season of salt, dirty spray, and rough driving conditions. That makes it a good moment to see if they've lost brightness, if the surface looks duller than before, or if buildup has settled in.
Spring lets you see what winter left behind. It's also a simple way to avoid putting the whole thing off until the next cold season rolls around.
Another useful check before winter
Before the days get shorter, a second look is often worth it. You're about to spend more time driving at night, with more rain coming, then snow and slush. Better to head into fall with headlights in good shape than cross your fingers and hope everything holds up once December hits.

What to watch for between seasons
You don't need to measure anything. Just look to see if the surface is yellowing, if the lens is getting cloudy, if it looks rougher, or if you're not seeing as well at night as you used to. Those are already good warning signs.
Even a brand-new car can start to cloud up faster than expected. This article spells it out: Why your brand-new headlights will eventually yellow too.
Do you need a fixed schedule?
Not necessarily. The real best schedule depends on how you use your car. A car that parks outside, gets driven a lot on the highway, and goes through every winter non-stop wears out its headlights differently than a vehicle that's less exposed.
In practice, a visual check in spring and another before winter are enough to stay ahead of things. The rest is mostly just keeping up with it regularly.
The right habit in Quebec
In Quebec, it's better to check your headlights a little too early than a little too late. A small loss of brightness is easier to fix than a headlight that's been left to go downhill for several seasons.
