Daytime Running Lights on Hybrid ( on or off )?

I'm not burning out light bulbs for no good reason? :dunno:
I was going to retire from this discussion, but I can't resist.

So, DRLs annoy you because you might burn one out. Fine.

What if they were LEDs with no chance of burn out and hardly any power draw? Would that obviate your annoyance and allow you to leave them on? Or are LEDs already passé and therefore better left unlit?

Just curious (and already regretting asking the question.) :rolleyes:
 
A cold Coors or Corona will be fine. :)
Sure, if those Western/Southern beers are your pleasure.... I think we can find them around here.

But there are some really attractive Eastern lagers I'd like you to meet. Very well built and, if I dare say, sexy. :thumbsup:

If your eyes are really that sensitive maybe you shouldn't be driving at night
Thank you, doctor. And this from the guy whose eyes are so sensitive to window tinting. Great that you can sympathize with another driver.

And as I said, fog lights annoy me. I never say they blinded me. If you need them to find your way every night, drive on.

So I'll just continue to enjoy my window tinting. And you can drive around the SJ all you want every night with your fog lights on. Macht nicht to me.

If you ever get to Cleveland, I'd love to buy you a beer.
 
there ARE no lights on a stock TCH XLE that simulates a "light show". .
Thanks for 'splainin' that to me. I had no idea.

Perhaps you are confusing some other vehicle's lights as such? Like perhaps a dune-buggy with light bars top and bottom with 18 individual lamps?? Or perhaps you got blinded by my buddy's 68 Chevelle that had two aircraft landing lights installed in lieu of high beams? Now THAT was impressive...
See, you know exactly what I was talking about.

Or...maybe you are just too easily annoyed and should ask your Dr for an Rx.
Perhaps you're right. Or maybe my eyes are more sensitive at night than yours are.
 
I tried a number of days using my daytime lights on / off and I thought I noticed an mpg (+/- 2 ) difference (yes Really)
And you withheld this information because???

My (car calculated) MPG can vary +/- 5 mpg every day. With the DRLs on at all times.

Thing is, there are so many factors that affect mpg, unless you do controlled track testing, there is no way to isolate the effect of just one factor in actual driving.

Anyway, I'm sorry. And welcome to the hybrid world. I think it's fun. Bet you never imagined your question would start all this -- and never actually get the kind of answer you wanted.
 
One of "what"?? Our fog lights don't impede anyone else's vision, so what's the snide comment about?
Personally, I get annoyed whenever I see a light show coming at me at night. Especially on yahoo pickemups with fogs, light bars and all. I know your fogs are very dainty and non offensive and nothing at all like that. But it is extra lumens in my face, and, to quote another Californian, (SDRider, about DRLs): "I just think they are useless and annoying".

Of course, I don't agree with SDRider's opinion about the DRLs.

And everybody's strongly held opinions are all over the board on this lighting stuff. And going back to where this all started -- to ask whether someone has tried driving with their DRLs on and with them off and noticed any mpg difference? Really? And that's why, from the very first post, this thread has been completely useless. But sort of fun. If you like your hormones exercised. IMHO. WTF! YMMV. Whee! ;)

And hey, I don't drive much at night, but last night I was out on rural roads and the automatic high beams on my car were working flawlessly. Love those things. Can't we talk about them now?
 
I believe your assumptions are off. If we just consider highway use, to eliminate variables, it is known that the power required at freeway speeds on a modern midsize sedan at 60 mph is around 20hp. That would be 15kW. Hence the DRL's would consume .67% of the energy, or roughly 1/4 of a mile per gal. Not a lot, but not completely insignificant either.
If this is actually the case, Toyota should put LED DRLs on all it's hybrids. Mine has them.
 
Putting aside my feeling that a car with a blank spot where the fog lights should be looks like Lady Gaga without lipstick....

My only use for foglights is when going slow at night over a very potholed road. The low foglights let me see the craters to avoid. Otherwise....

Go Gaga! Applause!! :clap: :clap: :clap: :clap:
 
don't often get fog in San Jose, but we have the light switches set to turn on the fog lamps automatically with the headlights. I like plenty of light to illuminate our roadways.
Oh Lord, you're one of those..... :D

So maybe we can redirect this thread to opinions on fog lamps instead of DRLs. :lol:
 
No need to turn a legitimate question into yet another argument about DRLs.
The OP brought the safety factor up, so how can the question of DRL safety be off topic?

It's a no win argument to be sure. Some folks are annoyed by DRLs. You can't argue that they shouldn't be annoyed. And they are positive that the other driver always sees them. Not sure how they know. Or that some other driver is going to be stupid, no matter what. That's a fact.
 
I know keeping them on helps with safety, but I am curious if any of you have actually noticed a difference is gas savings by keeping them off or is the difference in savings so small it does not really matter?
Since I always keep them on for safety, and since my DRLs are LED, I have to nominate you to do the testing. Just be sure you account for the effect of other variables including:
  • ambient temperature,
  • wind speed,
  • wind direction,
  • relative humidity,
  • use of headlights during rain,
  • use of wipers during rain,
  • amount of time the radio is playing,
  • length of trips,
  • number of traffic lights you actually stop at,
  • traffic conditions,
  • weight of cargo being carried,
  • tire pressure,
  • quality of gasoline,
  • use of A/C,
  • whether your windows are open or closed,
  • whether your sunroof is open or closed, and
  • other variables I haven't even thought of

Let us know your test results, please.
