Well, let’s see…..I last made that effort in…...1978, I think. So I guess that means (if I check tomorrow) that my answer will be…...(‘88….‘98…..2008…..2017)

Every 39 years….

On the upside, I DO come to complete stops (well….OK….most of the time, I mean….)

Not as often as I should, but I try to be always aware of them. Why checking the lights isn’t a part of a normal vehicle service I’ll never understand. Money to be made there!

We all bitch they didn’t signal, or they have no brake lights, or they have a headlight out.
But people seldom check their own vehicle to make sure all theirs are working.
As a truck driver I am required by law to do what is a pre-trip inspection before I start my shift, make sure all the tires,are good ,brakes adjusted, fluids are up, and ALL the lights are working.
That has carried over to my private vehicle and you know what it’s 19years old and everything on it works, why can’t the average driver do that as well ,if we are all such great drivers?

Every time I get a violation for a light being out.

Close to never. I guess I’d notice if a front light wasn’t working, but I could go a long time not knowing other lights aren’t. Hopefully, someone would notice and point it out, or hopefully a cop would give me a warning if something wasn’t working.

I’m guessing they get checked during a service.

I’ll check now and then now that you mention it.

@JLeslie Haha, me too, close to never.
I had a friend check for me maybe a year ago one day, it crossed my mind but yes, close to never for me too.

I check when I come home or leave after dark; I can see the lights in the glass door. I don’t keep spare bulbs but I did just order new switches for my speed control. I’m going to use the instruction and do this myself. The switches were $35. No telling what a car place would charge. I could not believe the switches melted. Inside my car gets so very hot during the Summer down here in South Florida.

Every month or so, I drive up to a storefront where I can see my reflection and check the lights. On Sunday or at night when the business is closed and the lot is empty it takes just a minute to look at front and back.

I bicycle a lot and if a driver’s window is open I let them know if they need a tail light or brake light.

One time I had the opportunity to roll up to a cop car and tell him I was letting him go with just a warning “this time”.

@Call_Me_Jay Hahahaha! That’s how to roll!

Never, unless for the headlights, I check the reflection in something in front of me to see if they’re both working. My car is only two years old so chances of lights being out are slim.

Once a week, or maybe twice a month.

Every couple of weeks.

It is surprising that so many people who have combination (red, no yellow) brake/turn and tail don’t know that the tail light might work, but the brake/turn may not since those bulbs have two filaments. The same can be said of cars with a yellow turn lens, and a red brake/tail. (Tail lights are only so bright when on, brake/turn are VERY bright.)

We have staff for that, part time of course with only light duties…hahahahahahahahaha

Every oil change

Oh, never. I find out quick enough!

Fairly regularly.

Last last night I spotted a vehicle headed toward me that looked like a motorcycle but turned out to be a car with one headlight out. Next morning I checked my own car with the help of a friend, who stood behind the car while I pumped the brake.
