What's wrong, in plain English

Toyota is recalling certain Tundra vehicles because the electrical circuits for the headlights may power the high beam and low beam bulbs at the same time. When both beams are powered together like this, the electrical connector for the headlight can overheat.

Where do I find my VIN, and what do I tell the dealer?

Your VIN is the 17-character code on the lower left of the windshield, on your registration and usually on your insurance card. Enter it at nhtsa.gov/recalls to see whether this recall is still open on your car. When you call the dealer, say you have an open safety recall and give them NHTSA campaign number 21V688000.
