Auto Headlights..

[Pearlturbo]

I think this is topic where a debate can happen lol, but I've read mixed comments about the auto headlights WITH HID option... Can it cause damage to the HID system?

My Genesis comes with the HID, and auto leveling/cornering feature and just wanted to know if it's ideal to have the headlights set to auto with an HID system.

I believe there would be a "yes it would cause harm" to an aftermarket HID system, but how about OEM?

I have kept both of my cars in auto mode, never had a problem. Besides, there's a warranty for that.

So scientifically, frequent startups of any HID bulb cause shortened lifespan and damage.

With that being said I also leave my OEM HID's in Auto mode. I haven't had a problem and replace my bulbs frequently anyway so real world has proven my science to be irreverent lol

I always leave my headlights "on" the car automatically turns them off when you turn the car off. So no risk of killing the battery. But honestly it has nothing to do with lifespan and whatnot. It's just cause it looks better With them on. The led strip and the low beam just look better than the stupid dtr lights.

Though on a sunny day, I don't bother turning my lights on. I do turn them on during morning daylight and later afternoon daylight. Having lights front and rear during the sun glare hours is just safer. I obviously don't use auto because I use them more than what auto would provide.

Technically yes, but I wouldn't worry about it. The difference it makes in bulb lifespan will be negligible unless you sit in your garage during your free time and turn the headlights on and off in quick succession.

You change your bulbs frequently?

There is a delay built into the Auto feature. Say you are approaching a wide bridge:

- Sunlight sensor detects lack of light, sends signal to BCM, BCM signals ballasts to ignite.
- Lights come on, but you are now exiting the cover of the bridge
- Sunlight sensor detects sufficient light, signals BCM to turn off headlamps, BCM waits until minimum time on has been satisfied and then signals ballasts off.

^^. Agreed but still will kick on lights when I pull into our garage.. Even on the brightest days.. With the HID life being shortened because of quick turn on/off, we do not leave it on auto most the time.

On the 2015, auto has a auto dimming high beam feature. When road is open and free of oncoming traffic at night the high beams kick in auto. When cars approach, goes back to basic low beam like function. In this case the high and low beam are the same bulb and one filament. There is a cool shutter system that flips the light projection within the lens system for high beam.

I knew this would get someone lol. Yes, I change them once every 2 years. I have a source on great bulbs to inexpensive prices and I worked at a hyundai dealer so they change them for $20 cash. The whole process costs me $70 so why not do it often to have the best possible vision at night?

How difficult is it to change the bulbs? I have been thinking about a different (whiter) high beam bulb, but it looks like a PITA to get to them...

 

[OneFunGenesis]

Its not easy. Much easier with a lift. The front bumper has to come off as the light housings have to come out

 

[amartz]

Somebody posted on here that the results for changing the bulbs to a whiter bulb weren't good enough to be worth doing. Specifically, the DLR mode still looks yellowish, even with the new whiter bulbs.

 

[OneFunGenesis]

I have 5000k HID's and have loved them for years. Wouldn't trade them for 4300k ever again lol

 

[FastDEW1]

Take the bumper off just to change the lights? Wow..... I will run the stock bulbs until they wear out. Then trade the car! lol

I changed my highbeams in about 15 minutes On my '13. It's not really difficult.
You just have to take off the plastic guard. There is a good walkthrough if you google it.

High beam bulb is more difficult than the low beams. Better than my G35 where you had to remove the bumper.

 

[Tailwalker]

I'll probably give you a call regarding this. Need matching temps...

My Genny gets parked inside a garage. Starting the car inside the garage causes the lights to come on. Backing out causes them to shut off immediately. Opposite is true when parking the car. I have no scientific facts to back it up but I have always believed the more you turn on/off lights the more life you suck out of them.
