Is it normal for Acura lights to dim at stoplights?
Every dealership will encourage you to take a vehicle for a test drive when you stop by. It’s not just because we like sitting in the passenger seat while you learn the ropes. After all, each test drive puts a few miles on the odometer. No, it’s entirely for you. Even in new cars where you’re unlikely to be listening for any issues, it helps to go on a test drive and get a feel for whether you enjoy driving a vehicle and ask questions about any quirks you might notice. Still, some things are likely to slip through the cracks. If you’re new to your Acura, the first time you drive at night you might be wondering if it’s normal for the lights to dim when stopped at stoplights. Here’s what’s going on.
What causes Acura lights to dim?
You’ll be happy to know that there’s no big mystery or sign of failure when this happens in your Acura. Essentially, you have a computer in your Acura that continuously monitors electrical output. At stop lights, the system tends to reduce charging so it does no more than keep up with demand. When idling, your vehicle naturally has fewer overall electrical demands, but this increases once more when you begin moving again.

This sudden change may cause the lights to dim for just a second as the computer adjusts to the change, or surge, in electrical requirements. You might notice something similar happens when other systems, such as your air conditioning, turn on and off.
So why does Acura have this ongoing monitoring? Every little bit helps when it comes to improving efficiency and limiting the load on the engine.
