When you get behind the wheel of a new or unfamiliar car, there are always a few distinct features, lights, or actions that might catch you off guard. Who hasn’t turned on the windshield wipers when trying to put the headlights on in a friend’s car? Those vehicle quirks aren’t limited to unfamiliar vehicles, however. One question we’ve received from Honda owners is about their vehicle’s headlights momentarily dimming when they are at a red light or stop sign. Although it’s momentary and creates no real problems, it’s worth exploring.
That temporary dimming of headlights is actually a completely normal vehicle function caused by variations in the electrical system. When the onboard computer of the vehicle realizes your Honda is at idle, it won’t send more electrical charge than necessary, as your Honda is constantly working to increase fuel economy and reduce vibrations.
As part of that effort, electrical accessories are turning on and off, thus changing the rate of electrical charge. As the onboard computer responds to those changes, the headlights or interior lights of your Honda may momentarily dim, then re-illuminate to their normal state.
If you notice the lights on your Honda temporarily dimming when you stop, just know that it’s part of your vehicle’s effort to maximize fuel economy and vehicle performance.
