Why does high beam work but not low beam?
Headlight Fuse or Relay
If a headlight fuse blows, it could cause the headlights to stop working. Most headlight systems are also designed with a relay that switches the power between low beam and high beam headlights. If this relay goes bad, it could allow power to the high beams, but not the low beams.
What would cause low beam headlights not to work?
Most headlight failures that are limited to just high or low beams are related to a relay or the high beam control switch. Headlights work but seem dim. The cause: Foggy lenses, worn out bulbs, or a charging system issue. The fix: Clean the lenses, replace the bulbs, or repair the charging system.
Why do my headlights only work on high beam?
Like all electrical systems, the headlights in your vehicle have a fuse in the circuit to prevent too much electricity from reaching the bulb. There will also be a headlight relay that switches power from the low beams to the high beams. If the fuse goes bad, you likely won't have any headlights at all.

How do you test a low beam headlight?
Measure the distance from the ground to the headlights to ensure the suspension is level. Check the inclination value on the headlight. It's usually on the shell of the reflector. 1% means the low beam tilts 10cm for every 10m, and 1.2% means the low beam tilts 12cm for every 10m.
Are low beams and high beams the same bulb?
High beam and low beam are two different beams of light, with 2 distinct functions. In most cars, each beam has a separate, single-beam bulb for producing the light. In other cases, one bulb, with a dual-filament, can produce both the low and high beams through a single bulb.
Why won't my high beams turn on?
By far the most common reason your brights will stop working is from a blown fuse or a bad relay. ... Or, it could be a bad relay.
