Since we all claim to be great drivers, how often do you make sure all the lights on your vehicle are working?

I check mine just about every time I drive it.
I have a drawer in the tool box full of spare bulbs for both vehicles.

Never (before I start driving).
Well, that’s not totally true, I realize now; when I come up to the car I unlock it with the key fob, and then all blinkers turn on.
But thanks for reminding me, I’ll check my brake and reverse lights tomorrow!

Ah, and just like @zenvelo, I always have my lights on (automatically); night or day.

My car (and most cars built in the last 25 years) has ways of telling me when a bulb is out. So as long as it isn’t telling me a bulb is out, I am confident that all lights are working every time I start the car (I drive with my lights on all the time.)

At least once a week, have some spares. Headlight HID bulbs are almost $200 each, no spares.

I have to admit, I only check them when I pull up to or back up to a glass window; I can see them in the reflection.

I do what @smudges does.

Ditto @smudges and @jca2 Guilty as charged I suppose.

I check my lights every now and then. I can see reflections of my lights when I drive up to a storefront parking space in a mini-mall.

I don’t care for any “we all” generalizations, whether pertaining to driving, writing, or anything else. You can’t draw a reasonable conclusion from a false premise. I, for one, do not claim to be a great driver, just as some others around here are not bothered about how their writing measures up. As a very late learner, I’m extra careful because I know I’m not highly skilled.

Fine but being extra careful how often do you make sure all your lights are working?

Everytime I start the car. There are sensors to tell me if a light is out. I also notice these things On prior vehicle without that luxury.

The majority of vehicles (new or old) that have a light out is simply due to ignorance on the drivers part. They know, but don’t care until they are pulled over.

When my oil is changed they check. I check my headlights every time I park at night; I can see their reflection when I park at home and often other places.

At minimum every oil change but usually more frequently. I have most of the bulbs I need to replace any that die in my car already.

I make a point of walking around the truck with lights on once a week – usually Saturdays.

My old car does the rapid blink if one is going out so I don’t check often.

@SQUEEKY2, I’ll totally give you that. I almost never think to check, but I will now.

I’m not too much of a road menace, though. I bought my car new in 2012 after I had stopped commuting, and I have less than 22,000 miles on it. I seldom go more than ten miles from home, and I stick to surface roads as much as possible.

When the cops stop me!
