Can a low beam headlight work on a high beam?
I just had this problem recently with my driver-side low beam. First couple times, I switched quickly from low to high beam and back again, and it came back on and worked for a while. But that trick stopped working. Bulbs were fine, fuses were fine, relays were fine.
Why are my high beam lights not working?
On some vehicles, particularly those with HID headlights or solid-state circuit protection (Zener diodes or high beam circuit breakers) installing the wrong bulb might result in intermittent headlight operation or no high beams at all. The wrong bulb might not ignite at the right voltage or draw too much current for…
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.

If this relay goes bad, it could allow power to the high beams, but not the low beams. 1. Headlight Bulbs This is the most common reason we see for why a car’s high beam headlights work but the low beams don’t.
Why do I need a high beam relay?
No good reason comes to mind. Increase the intensity and improve the spread pattern by keeping all four lights on when in high beam mode. Easy 10 minute installation. Includes relay, color coded wiring and fuse protection. Will work on all trucks, including those with daytime running lights.
