Interior Light
The interior light illuminates the cabin when doors open or when switched on.
What is Interior Light?
Most turn off automatically after a delay. LED lights use little power. Door switches control it. Some cars switch off interior lights automatically to protect the battery. Upgrading to LED reduces load and heat.
How it works
The body control module switches the light.
Why it matters for your car
A light staying on drains the battery. Faulty door switches are a common cause.
