Signals help communicate to other drivers so that you may safely change directions, lanes or activate your emergency flashers.Įnsuring your turn signals are operational is paramount for driving safely. Turn signals are a vital component for driving.

Turn on your vehicle and test the turn signal to ensure the replacement bulb is working.Reconnect the electrical connections and replace the housing if necessary.If the bulb has alignment pins on the bottom, ensure they align with the corresponding openings. Depending on your vehicle, you may need to pull the bulb straight out or push the bulb inwards while turning.

Remove the worn-out bulb by turning the socket counterclockwise.

Remove the electrical connecter by pushing the locking tab down and back.

Remove the old turn signal bulb by opening the hood and locating the unit requiring replacement.

Depending on your vehicle’s design, you may need to unscrew the mounting screws to remove the turn signal housing before beginning the replacement steps. Remember to avoid touching the glass area of the new light bulb with your bare hands to avoid damaging the unit. However, if you don’t feel comfortable replacing the bulb yourself, take your vehicle to a trusted automotive technician to complete the service for you. Replacing a turn signal bulb in most cars is relatively easy.

Clean turn signal components and surrounding areas.

To resolve your vehicle’s fast-blinking turn signal issue: Taking your vehicle to a trusted automotive technician will likely save you some time and some grief, especially if your car is experiencing an underlying electrical problem. These days, modern cars have many nuances that can make an otherwise simple task rather tricky. In older vehicles, replacing a bulb, relay, or fuse might have been a simple task. Relays and flashers can wear out over time or succumb to water damage, extreme temperatures, or other environmental conditions. If there is a lack of voltage in the car, the indicator is likely to blink fast.Ĭorroded, fried, worn through the insulation, or loose connections will alter the resistance and blinking speed. Similarly, bad combination switches can be the res Poor Ground Connection or Inadequate VoltageĬombination switches that are dirty or need cleaning are good indicators that the connections are in disrepair.

You can also inspect each bulb to check for broken filaments, darkness, or cloudiness on the glass portion of the bulb. To determine whether your bulbs have failed, test each signal direction to see if any bulbs are out. A failed bulb interrupts the resistance in the circuit, sending an altered current through the signal. A change in any of these elements can alter the timing of the blinker.Ĭommon causes for fast blinking include: A Failing or Failed BulbĪ failed bulb is the most common cause of a vehicle’s turn signalīlinking fast. The circuit has defined calculations for its current, resistance, and voltage. The circuit’s current is dependent on the load demand, also known as bulbs. The current that flows through the band causes the metal to heat and cool by straightening and bending to break or complete the circuit to create the flashing motion. Flashers are engineered with a small band of metal that is heat resistant. Instead of a solid “on” state, the power is sent through a flasher to create the flashing motion.įlashers are temperature-controlled and designed to bend at precise intervals based on electrical conditions. It then activates and sends power through a second load circuit that includes the bulbs to corresponĭ to your chosen direction. The control circuit completes when you move the signal arm up or down to activate your right or left signal. Power for the signal runs through a fuse from the battery to the turn signal relay. The turn signal circuit is pretty standard within most vehicles. Read on to find out the answer to your most burning question, “why is my turn signal blinking fast?”. When something is not right, the speed of the blink or the sound of the click can increase. Your turn signal tells other drivers what direction you’re planning to go and yield to your next move.Īccording to SAE Standard J590b, functioning turn signals have an average cadence of 60 and 120 blinks per minute. Turn signal, blinker, indicator light Whatever you call them, they are the only communication you have to drivers around you.
