The indicator bulb is one of the most important, yet often overlooked, parts of your car. It enables you to signal your intentions to other road users and pedestrians so that you can safely turn at junctions or change lanes on a motorway.
It is also used in emergencies when you switch on the hazard warning lights. Just because the indicator bulb isn't in constant use, like the head or taillight bulbs for example, doesn't mean that it cannot wear out over time. A faulty or broken indicator bulb could result in a serious accident and injuries to you, your passengers and other road users or pedestrians so it's worth checking that the indicators are working on a regular basis.
