I would say there is almost certainly a little wheel somewhere on your dashboard to adjust them. My Land Rover has this.

A vehicle in the US that would be colloquially referred to as a 'truck' almost certainly does not. Headlight level controls are extremely rare in the US.

Been driving about 20 years in the US, owned eight or nine cars (mostly small to mid-sized sedans and minivans) over the years between me & the wife, and I can't recall ever seeing headlight level controls.

I'm an enthusiast who has owned dozens of vehicles and driven around a hundred. I have only seen this feature on a couple of euro luxury cars.

Interesting! In Europe you not only have cockpit adjustable lights but auto leveling very common. Of course the consumer ends up paying for that, and they do cause maintenance issues.

> In Europe you not only have cockpit adjustable lights but auto leveling very common

Cockpit adjustable lights have been required by law in Europe for about 20 years. When Xenon lamps arrived, auto-leveling was added as a requirement for them.

Bit the bullet and read the Wikipedia part, which was excellent. Cockpit adjustable headlights since 1948!

It's been a feature for ages in the EU on even the most cheap crap you can buy for money.

They have manual adjustments in the engine Bay Area on most cars

They are usually in the bottom of the bumper as a little screw, or on the inside of the engine bay in the front near the top of the radiator. They are in most cars.

We were talking about driver controls, on the dashboard.

The manual adjusters on the headlight are not intended to compensate for daily variances in vehicle load.

Not if they are halogens. I've only seen manual adjustment on HID-equipped cars, and only older ones. Most anything modern is auto-leveling.

It's bog-standard on my old Land Rover with weak yellow halogens. I think you'd find it hard to drive with a load in the back without them!

I have only seen manual adjust on halogen and only auto adjust (because it's a requirement in Europe at least) on Xenon.

My last Japanese car with HIDs had manual adjust. Everything I've owned since was auto leveling. I've never owned a manual adjust (unless you count the screw on the headlight itself...) on a halogen headlight equipped vehicle. And I've owned a lot of vehicles over the years.

Indeed, my Bentley has this feature but my Ferrari and Lamborghini do not.

I'm not sure if you're trying to mock the fact that I said I had a Land Rover. That's not very kind.

I mean an old Land Rover Defender - a working vehicle that rattles and doesn't even have air bags. It still has a headlight adjustment wheel as it's a functional feature, not a luxury.

Those are awesome. Yes, I was just teasing a bit. I hope someone got a chuckle out of it. Hope everyone has a great day. Stay safe!
