Frequently Asked Questions

Are DRLs the same as headlights?

No. DRLs are a separate lighting circuit that provides reduced intensity illumination during the day. They are not bright enough for nighttime driving and do not activate tail lights.

Can I disable my DRLs?

While some vehicles allow DRL deactivation through the settings menu or dealer programming, disabling them may violate regulations in certain states and countries where they are mandated.

Why is one DRL dimmer than the other?

Uneven brightness can be caused by a partially failed LED element, a dirty lens, or a high-resistance connection. If the DRL uses a halogen bulb, the bulb may be nearing end of life.
