Hi there, today my low beam went out on the left side but I noticed the high beam works and the right side low also works. This is on an 06 Dakota. Trying to figure out what the issue might be. Thought it might be a fuse? I just replaced two others but i couldn’t find one labeled low beam in the diagram for the fuse box.

The the headlight bulb has two filaments inside it: one for low beam, and one for high beam. Sounds like the low-beam filament in the bulb blew, and it's time to replace the bulb.

Just had to replace a blown headlight bulb a few weeks ago actually...Swapped as a pair with Sylvania Xtravision from Walmart, and it actually made a huge difference in night visibility!

Yeah, there is not a fuse for only the low beams, especially one side. Either it's the bulb, as stated already, or a wiring issue.

Appreciate everyone’s help, didn’t realize the bulb had different filaments for low and high beam, I’ll replace the bulb and report back.
