Model years: 2011 - present
Brake light is a light indicator in the rear of a vehicle, that produces red light whenever driver make use of brakes. Put another way, it is a notification the vehicle is about to throttle down or will terminate moving at all. Making sure brake lights are operating is an essential subject so that others can easily predict you are about to stop the vehicle. Supposing brake lights are not working, other drivers might not detect quick speed reductions in time and the cars might be involved in the accident. When noticed, that either brake light is not responding, do not postpone and replace the bulb in the short run. Prior to fixing dead brake light, be certain you acquire a proper bulb.

The life-time of a bulb is limited. Sooner or later, it will burn out and will have to be replaced. Bulbs, made of high quality materials, tend to last longer. It's recommended to use well known brand replacement bulbs.

If bulb burns out right after installation, your vehicle might have a problem inside electrical system - have it checked by auto electrician.
