Hi, my name is***** your mechanic automotive expert, and I will be happy to assist you today. In some cases, I may need more information to assist better. I apologize for any delay.
Dear customer, the low beam does not work with a fuse but it works with a relay known as the flasher for the indicator and hazzard lights, these are the ones that make the lights intermittently.
But the problem is more related to the controller of the lights due to the fact that sometimes when you activate the light in one direction the other is activated, this means that there are false contacts, you can surely be presenting rust or corrosion in the controller.
So my recommendation is to first check the status of the light switch or controller, I also recommend you check the light bulbs.
My goal is to give you the best advice i can based on your description, I hope to be helpful, if you have any doubt please do not hesitate to reply back.
Kind regards, Sebastian.
