Laws regarding lights?

[Lucky225]

Many states prohibit running fog lights and head lights at the same time. I got stopped for that in LA, and a buddy got a ticket here in TN for it.

Did you mean to say what you said?

Most states prohibit more than 4 forward facing lights on at a time. That is why if you have separate flashing (passing) lights, and you have your fogs on, when you hit the flashers the fogs cut off... its actually a US import regulation on cars for sale in the US for road use if I recall correctly. BTW, there are many cars in the US that don't run fogs without headlights...

Are you referring to high beams as "passing lights"? not tryin to be a smarta$$ just tryin to figure out what yall are talking about.

My fogs turn off when I hit my high beams, I always thought this was because fog lights are designed to illuminate below the fog (or atleast below eye level), but if you run your high beams in the fog, the light will just reflect back off the fog and actually decrease visibility, hence if using fog lights for there true purpose, you shouldn't need high beams at the same time, it would be counterproductive.

I always have my fogs on, just habit when I turn on my lights I turn on the fogs as well.

Had a pair of 150 watt kc's on the front of my lifted jeep, were absolutely blinding so I only used them if I was the only one on the road, or off road, they were good for moving over left lane hogs, especially at night.

I always liked how you're not allowed to run just your fog lamps and must be running headlamps at the same time

V.C. Section 24403 - Foglamps

24403. (a) A motor vehicle may be equipped with not more than two foglamps that may be used with, but may not be used in substitution of, headlamps.

I'm not sure that's the case. I believe that should written to prevent people using fog lights instead of headlights e.g. during night when there is no fog. Runing headlights and fog lights in the fog may be counterproductive.

No trust me, this was DRILLED INTO MY HEAD during driver's ed, AND it's a trick question on the Ca DMV written test (When can you operate a vehicle with only it's fog lights? a) parked b) during fog c) never. - the answer is C).
