Why do high beams work but low beams don’t?
This is the most common reason we see for why a car’s high beam headlights work but the low beams don’t.

Why is my car’s high beam light not working?

How does a high beam light bulb work?
Get familiar with the fuses and relays that control your headlights. The headlight switch usually doesn’t control the headlight bulbs directly, but through one or more relays. The headlight switch powers a relay, which powers the headlight bulb. This protects the headlight switch from the high current used by the high beam headlights.
