Question Low Beams Went Out - What could cause it?

So my girlfriend has has a 2008 Subaru Impreza. She has her low beams on anytime the car is running and never shuts them off. Coming hime the other night she got in her car and no low beams, but the high beams work fine and the driving lights (daytime running lights?) also work fine.

I checked the bulb on the drivers side and it looks like the filament is intact. Both the high beam and low beam relay sound ok and no blown fuses. The high beam relay does click normally, and the low beam has a softer sounding click when you turn them on/off compared to the high beams. Is this normal? Or possibly a faulty relay? Are the high and low beam relays the same? (maybe swap them and see if the high beams go out and low beams work?

I do not have a multi-meter so cant check to see what is coming through for volts.

Just because a filament "looks" intact doesn't mean it is. Try different bulbs, it may just be that.

Those that want to check electrical problems out should have the proper tools to do it. Once you start using a meter you will wonder how you ever got along without it. Even a good quality meter is something most folks can afford.

I spend <$30 on the meter I have and it does what I need it to. (and the probes are so sharp I usually bleed from at least one finger whenever I use it)

fuses and bulbs can "appear" to be good, but until you either test them with a meter or swap them with a known good one you won't ACTUALLY know anything.

Are you sure you are checking the right bulb?

We have had many people check bulbs for low beams, only to find out they were really checking the high beam, bulb.
