Running Lights Fuse Keeps Blowing – What Should You Do

It is impressive to discover that the running lights fuse keeps blowing, isn’t it? Maximum people do not know about the short, so that they can’t diagnose the short! The fuse blows once if the running lights are turned on. It is mostly notified during the night. The happening causes the interior dash instrument panel heavily. Without the specific panel, all the headlights, brake, and signal lights work fine. I have once got one blown bulb and pulled it out from the light source. I have checked it all, including the exposed wiring and the frame. There was nothing! The bulbs are good, and bulb sockets look undamaged either. Therefore, I asked experts to solve this puzzle and got terrific answers. Let’s discuss it with you!

Expert’s suggestion:

The expert’s suggestion: It would be a better idea to find a short by replacing the blown a fuse. The replacement should be with a pair of spade terminals. Hopefully, you know about small jumper cables, right? Connect them to a 12 volt light bulb. Depending on the brake light’s structure, I can say that after connecting the small jumper cables, your vehicle’s bulb will be fully illuminated and hot. Then, unplug the electrical connectors and move around the things responsible for the short go away. Unplugging the connector will make the bulb dim or go out! One of our teammates added that he fixed his tail light relay, which was melted by $32.00.

Why does my light fuse keep blowing? 4 reasons to know!

Not only in a vehicle, but all the electrical system has a system of circuits controlled! The circuits are protected with circuit breakers and fuses. To avoid a vehicle’s blowing lights, it is essential to know why a blown a fuse. It mostly happens if the breaker is tripped and damaged. In most cases, the fuse gets popped up!

Why does my light fuse keep blowing

  • The first reason for getting a light fuse blown is the ‘Overloaded Circuit.’ The overloaded circuit is the most common reason that trips a circuit breaker and occurs circuit attempting with a massive electrical load. The overloaded circuit happens due to the appliances and light fixtures. When their fixtures are operating simultaneously, the internal circuit heats up and trips the breaker. The breaker is engineered with a spring-loaded component. Suppose an overloaded circuit runs through the pathway of the breaker that renders the circuit inactive and dead. A circuit breaker may reset to the ON position and indulge the spring mechanism inside. The circuit breaker is a fuse and is stable to match the wires’ maximum capacity in the light circuit. If you regularly trip the fuse, you make excessive demands on the circuit and lead the heat to a dangerous level. What happens next? You may need a service upgrade and move some appliances to other circuits.
  • A short circuit is a reason that lets a light fuse tripping! If the bulb’s wiring system touches a neutral wire, you get a ‘Hard Short.’ A short circuit happens due to the unimpeded flow of electricity. The reason for this unimpeded flow is due to lowered resistance. It leads the light fuses to activate suddenly by a tripping mechanism. A short circuit is often not happened for the circuit wiring. It happens because of a wiring problem or a plugged device into an outlet in the circuit. Fixing ‘Short Circuit’ is a professional’s work. If you’re a professional, please diagnose the problem and fix it soon. When you see a circuit breaker trip again, be assured of the presence of a short circuit.
  • ‘Ground Fault’ is known as a particular type of short circuit. It occurs if a hot wire is in contact with the ground wire or wood framing members. A ground fault is a dangerous short circuit and occurs on wet or oily surfaces or in outdoor locations. The short circuit happens inside the light source and carries a risk of shock. Comparing the other problems, you can fix a ground fault. Isn’t it better to prevent the ground fault than fixing the problem later? Well, You should ask a guide about the possible area where the ground fault can happen and then protect the area with GFCIs (Ground-Fault Circuit Interrupts).
  • In recent years, the ARC-FAULT circuit is known as one of the particular types of circuit fuses. This circuit gets tripped due to the power fluctuations’ overloads and occurs sparking between the wire connections. The leading light source gets loose by the terminal connection and occurs early wiring problems in the circuits. ARC protection is an essential factor and safeguards against light’s fuse. Repeated tripping is a signal of blowing lights. Check the loose wire connections and the cause of repeated arcing. You’ll get an easy fix anyway!


It is a loss of electrical power if you have recently faced running lights fuse keeps blowing! It’s one of the worst experiences that every enthusiast is familiar with or soon will be. No panic! The summer months are much suitable for a trip. Besides, it brings vulnerable time at a stretch. Have you tried replacing burnt fuses or reset the breaker? It is a wiring hassle. Don’t be discouraged. Here we go with some final tips that would help to replace fuses as a frequent occurrence. Here we go with minimum aggravation to complete the fuse replacement safely. Read us. 

Check the light source. The circuit list is installed with electrical components. Checking the list, you can identify the last installation. Besides, the outlets and lights can be checked on each circuit. You should be in touch with the additional outlets or lights in case of a replacement or resetting of the breaker. It’s needed. When replacing fuses, be careful if they are accessible to the circuit list easily.

You should use appropriate lighting on the task. Having a low version of running lights keeps blowing. It is not a new issue, anyway. Check the circuit list if the list is up to date and do an experiment to remove the burnt-out fuse at a time. Removing a fuse won’t affect the light source. Get a professional’s suggestion. It would be a bad idea to change the fuses with the power on. Be careful removing fuses and turn off the switch during the operation. Don’t try other stuff in an empty fuse socket. It triggers an electrical short. Why be in a severe fatality?
