One of our readers writes that his brake light and the turn signal is not working on one side! What’s the solution to this problem? Well, I have had this problem in a 2011 F-150 Platinum. The brake and signals light was not working on the driver’s side. I thought the fuses were misfired, and the bulbs were damaged. I replaced the bulbs along with the connectors. No avail! 

Finally, I got this as confusing lighting problems and decided to work with the basics. I called my teammates to check the power and ground of the brake light and light signals. Sometimes, you have a good base but having no power in it! But, if you see you have got a bad ground, repair it as soon as possible. You will get the simplest repair nearby. The BCM (Body Control Module) is known as the power side of these brake and signal bulbs. Check the BCM if it has power at the sockets. You should ensure power coming out of the BCM. You can establish a scanner on the vehicle that communicates with the BCM and troubleshoot the brake’s error codes and turn signal lights. You can purchase the ‘Foxwell Diagnostic Scan Tool’ on Amazon for this! The scanner can access the BCM and check the updates of the power and grounds at the BCM.

Brake & Signal Light Problems; Easy Fixes!

These lights won’t give you head-scratchers! We show you some specific issues of brake light problems. You should crop them up! Fixing these light issues would be comfortable for us. Let’s know how to solve the four major issues in four magnificent ways. Would you like to read us?Brake & Signal Light Problems

  • Has your bulb burnt out?

Do you know what crops up the most are? A burnt-out bulb! It is the reason you will find brake light problems mostly. The brake light disturbance relies on the time you hit the brakes! It sounds sarcastic, yeah? Whatever, it is true that depending on the illuminated estimation, vehicle’s model and bulbs feature, the brake light stables. If you have got a bulb that burnt out during that entire period, you should switch to LED lights. It helps you with a much longer lifespan. What if you have old vehicles? Try out still-featured bulbs for them. Be confirmed if the stock bulb is popped out. Then, go for a replacement! Hopefully, you can do it better with a basic set of tools! If not, find a mechanic to do the replacement for you.

  • Is the analog switched worn out?

The brake light is illuminated once you trigger the brake pedal, and an electric signal gets to the light source. Do you know analog switches get worn out after a period? Yes, maximum enthusiasts face the problem as the light source becomes dirty and loses the right signal’s ability. In case replacing the switch will be the real solution. It is straightforward to test brake light problems if you go to a mechanic. If you see three brake lights are out, it means the trio of bulbs died simultaneously.  

  • ‘BLOWN FUSE’

If the brake or signal lights have a problem in illumination, you must be going through a ‘BLOWN FUSE.’ Why am I saying like that? Sometimes, the lights are not illuminated by either side due to the brake light fuse. It does not mean your light switch is terrible! All you need to do is establishing the vehicle’s fuse box under the hood. You could make a useful passenger compartment if you wished! Be mindful of finding the fuse for the brake circuit. Probably, it hasn’t been blown. If it is, then replaces the brake circuit with a fuse of the same requirement.

  • ‘Bad Socket’

The fourth problem that leads the brake light and the signal lights misfired is having a ‘Bad Socket.’ Hopefully, you have got a single brake light and found the bulb as a real modification. Your next step should be checking the light socket as the brake/turn light’s problem is due to corroded connections in the socket. Most of the vehicles have worn wiring between the sockets that lead your vehicle to an intermittent connection. For being a solution, replacing a socket would be a simple idea. Once replaced, you’ll be benefited snipping the old wires. Plus, splicing in the new unit would be more genuine for the light brigade. Undoubtedly, it is an inexpensive part to purchase!

FAQ:

  • Are the brake light and turn signal the same bulb?

Most of the vehicles have emergency and signal bulbs packaged in a kit! The kit is known as a brake light. You can turn the emergency flashers and signal lights just in a try! It’s wise to try them by the end of the vehicle. Just hit the brake pedal! 

  • Can a bad turn signal switch no brake lights?

A bad turn signal switch can be a lot to examine! Those vehicles use the brake lights and signal lights as the same pattern; a bad switch can switch your brake lights off along with the brake lights. However, the third light will still be functioning. This happens as the brake and signal lights are connected with the same circuit. 

  • Why does my turn signal not work sometimes?

Maybe, it is because of the ‘Oxidized Bulb Sockets.’ Research shows that rust and dust can also be responsible for disabled turn signals. If rusted, the electrical contact is disrupted between the bulb and the socket. You have to clean the signal lights and maintain the car regularly. I hope for the best!
