Car: 2003 LX Sedan
Bulb: H4 Dual Filament (high/low beam)
Problem: Right headlamp not working, but when I put on the high beams it works just fine.

Some people online point to a relay issue, but shouldn't both headlamps have the same issue then?
Upon further research, it's more likely that one of the two filaments in the dual filament bulb has burnt out. In which case, I will need to replace the bulbs.

Do you agree that it's probably a bad bulb?
If I replace the bulbs, should I buy those LED ones on Amazon?
Or find a halogen one that matches what my car came with?

Thanks in advance.

choosing LED bulbs to be used in regular non-projector type housings is tricky.

First step is to always check the bulb

yeah, just remove them to see if the filaments are in one piece or more
