ok I tried to post on other headlight threads but they are too old. I have a 2000 Nissan Frontier V6. This morning on my way home from work I noticed my high beams work but both my low beams weren't working. I opened the hood and saw that I had one fuse for each headlight. The fuses looked ok but I switched one out just to check and still no low beams. What else can I check? I read somewhere about my headlight switch may have gone bad???? Mine is steering column mounted. A new switch is at least 80 bucks so I wanted to know what else I could check first.

well, it's possible that just the low beam of both headlight bulbs has gone out (assuming that you have the type of bulb where a single bulb does both high beam and low beam duty). the low beams almost always die first, because they're used so much more.

Hmmmmm that would be a cheap thing to check you are right. I'll try that. I just thought it was weird for them both to blow out at the same time so I figured it was fuse related or something.

Doesn't sound like the bulbs, but I am a n00b.

^ it seems odd, both bulbs goin at the same time- but i've seen it happen more than once... if you have a test light or multimeter check for power at the plug... otherwise i'd start with new bulbs and if thats not it, then start back checking wiring/relay(s)/switch

it actually makes sense for both of them to go at or at least near the same time.

So, in this case, it is legal to drive with your high beams on?

you can drive with fog lights as long as they are 55 watts.

We ain't talking about fog lights.

yes, as long as you are not approaching another vehicle.

there are two bulbs (or filaments) in one headlight. one bulb/filament is on for low beams, both bulbs/filaments are on for high beams.the lows typically burn out before the highs, because they are used all the time as opposed to some of the time. the bulbs/filaments have a certain rated lifetime. the lifetime for each is the same. since each low is used equally, each one in the low pair will burn out within a short time period of the other. now go change both your goddamn headlights and quit driving around with your fucking brights on.[/auto 101]wait... youre a cop? holy shit.[Edited on May 19, 2007 at 10:58 PM.

It's your bulbs. On my old Saab with daytime running lights they consistantly failed withing 2-5 days of each other.

replace bulbs. if that doesn't work check voltage at the headlight and trace your way back through the circuit

Not all bulbs have dual filaments.
