Brake light bulbs are the bulbs that light up when brakes are applied. These lights alert the following vehicles about the braking and help in avoiding a collision. If the brake fluid levels are low, your brake lights may turn on their own. It may create confusion on the road and may even result in an accident or penalty.
Incandescent tail lamp bulbs can last up to 5 to 6 years. On the other hand, LED bulbs can run about 10 to 12 years. The replacement cost of the brake light bulb is very nominal.
