Symptoms
- Headlight doesn't turn on but vacuum runs fine
- Light flickers on and off
- Light works only when the head is held a certain way
- Light was dim before it went out completely
Likely causes
- CommonBurned-out LED or bulbHeadlight bulbs have a finite lifespan and eventually burn out like any bulb.
- CommonLoose wire connection at the swivel jointThe wiring to the head often runs through a moving joint that can loosen or fray over time.
- PossibleBlown fuse for the light circuitSome vacuums have a separate small fuse just for the headlight circuit.
- Less commonFaulty switch for the headlightIf the vacuum has a separate light switch, that switch itself can fail.
What to do
- Confirm the headlight has its own switch and that it's turned on, if applicable.
- Check the manual for whether the bulb is user-replaceable and its bulb type.
- If replaceable, remove and inspect the bulb for a visibly broken filament or burned look.
- Replace the bulb with the correct type and wattage specified in the manual.
- Gently move the head through its swivel range while looking for the light to flicker, indicating a wiring issue.
- If wiring is loose or frayed at the swivel joint, this typically needs professional repair.
- If there's no user-replaceable bulb, treat this as a minor cosmetic issue rather than a functional one.
Tools and parts
- Screwdriver
- Replacement bulb (if applicable)
