A flickering light bulb can be dangerous because it may signal a loose connection, an overloaded circuit, or deteriorating wiring that can overheat and arc. Most flicker comes from a loose bulb or a failing bulb/LED driver, but steady or widespread flicker points to wiring, switch, or panel issues that need a licensed electrician. If lights dip when a big appliance starts, the circuit may be nearing its limit and should be evaluated. Our team routinely resolves these problems for homeowners in the Roanoke area.
Consider these next steps and warning signs:
- Hand-tighten or replace the bulb and test the fixture on a different circuit.
- If you smell burning, hear sizzling, feel unusual heat, or see scorch marks, turn off the breaker and call an electrician immediately.
- Schedule service if multiple rooms flicker, it happens at certain times, or after storms.
If you are unsure, turn the switch off and do not use the fixture until it’s inspected.
