Why does my indicator flash really fast

Hyperflashing is when the turn signals blink faster than your stock incandescent bulbs did. A rule of thumb is to find a resistor with twice the power rating. Here I would choose a mW resistor since those are the most standard ones. Usually, you can just use the cheapest resistor you can find with the correct power rating.

A resistor is a little package of resistance: wire it into a circuit and you reduce the current by a precise amount. From the outside, all resistors look more or less the same. As you can see in the top photo on this page, a resistor is a short, worm-like component with colored stripes on the side. Begin typing your search term above and press enter to search.

Corroded, fried, worn through the insulation, or loose connections will alter the resistance and blinking speed. Relays and flashers can wear out over time or succumb to water damage, extreme temperatures, or other environmental conditions. In older vehicles, replacing a bulb, relay, or fuse might have been a simple task. These days, modern cars have many nuances that can make an otherwise simple task rather tricky. 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.

Replacing a turn signal bulb in most cars is relatively easy. Remember to avoid touching the glass area of the new light bulb with your bare hands to avoid damaging the unit.

Turn signals are a vital component for driving. Signals help communicate to other drivers so that you may safely change directions, lanes or activate your emergency flashers. Ensuring your turn signals are operational is paramount for driving safely. A dysfunctional turn signal could earn you a traffic violation in some states!

Part 1: The Signal Circuit Power for the signal runs through a fuse from the battery to the turn signal relay. Damaged bulbs can often cause the turn signals to blink fast, as the resistance switches may soon start malfunctioning. With this, the switch causes the light to flash repeatedly and at some greater speed.

When two bulbs in a specific direction are in good shape, the flasher relay would be conditioned to flashlights at the correct speed. You can attribute this to both bulbs draining a specific current amount. However, when you find one of the bulbs on either the left or right side damaged, it causes the relay to start flashing twice as fast. Suppose you find your turn signal blinking fast with a new bulb; it could be due to the following:.

This case often results from water getting into the area, causing the relay pins to rust. Aside from this, the cause of the directional light blinking could be due to flasher relays that seem inadequate. What does this mean? That could be the cause of your dodge caravan turn signal blinking fast. How do you tell if the relay in your car is in good shape? The signal fuse may be burnt, and it would help if you check to be sure that it is in good condition.

If the turn signal fuse is bad, you would be needing a suitable replacement. There are various options available in the market.

You can find the maxi fuse, mini fuse, and micro fuse. Note: You may find the relay and fuse under the hoods or inside the vehicle. Kindly check with your car manual to determine the relay and fuse location of your car.

Whether your find your car or motorcycle turn signal blinking fast, it would be best to fix such problems. It would help if you first step down from your vehicle to access the turn signal bulbs. The indication you get from your dashboard may not be enough. So, park the car and inspect the bulbs from behind and in front of your vehicle. Then, look further to see the bulb or bulbs that blink at a faster speed. If you find all lights working in good condition, then there are no problems to fix.

In most cases, where the signal lights flash with greater speed, it is due to a faulty light bulb. Once confirmed that the signal bulb is burnt, a suitable replacement is needed. If you notice the bulbs in good condition but still find the turn signal hyper lighting, you should test the relay. Kindly note that a faulty relay would cause both the left and right signal lights to stop working. Replacing the relay may seem complicated for some folks. Hence, you may also decide to contact an expert to change the bad relay.
