Tesla, LED Headlights

Tesla, LED Headlights

The headlights are the first thing to greet your (eye)balls at night, yet are the lowest tech item on a Tesla. Please include an LED headlight option on my $90,000 X. My mountain bike has a 1,000 lumen LED lighter for $50.

Wah wah wah.

The car is expensive because of big battery.

How about we let tesla focua on actually BRINGING MODEL X TO MARKET. xenon headlamps are good enough.

Yeah. Sylvania and General Electric, along with others, will probably offer aftermarket solutions. AutoZone, NAPA, Pep Boys, etc would stock them...

@DTsea, the battery is not as expensive as you think it is...

What about laser light? Those are the future. I've driven a car with laser long distance light (don't know what you call them in English), and they are light years ahead of other alternatives. The road got completely lit up and I could see very far.

Apparently, laser based headlights are currently illegal, or at least not yet approved by the NHTSA, in the US. You may see them on European cars first.

All Lasers that I've seen have "do not point at people" type of warnings. The collimated light can damage retinas.

How do LASER headlights account for this?

@holidayday

You don't end up seeing any actual laser light. The laser just zaps a yellow phosphorus that in return creates a bunch of white light. That white light is what makes it out of the headlight assembly and onto the road.

LEDs are very efficient, a positive attribute for BEVs.

@Iowa: who do you know at Tesla? $90K sounds like a good deal. I'm thinking closer to $100K.

georgehawley.fl.us | July 1, 2015

and what the heck is a "mountain" bike doing in Iowa?

Here's a cute video comparing LED, Xenon, and Halogen light sources in headlight applications.

It seems that the directionality problem with the LED could be fixed with a reflector/projector lens designed specifically for the LED lamps.

Lasers are so vastly safer that all efforts should be made to get the costs down so they are standard on all cars, regardless of cost. There would have to be standard components and mass production of them, a veritable laser light gigafactory. Then only the housings would vary to fit the contours of different vehicles.

Laser > LED > Xenon/1998

I just wanted to say, the "laser" comes from a LED. And that Tesla would not use a 2 diode system, more likely 25-35 on each side...

FelixMendeldog | July 6, 2015

I am reasonably certain Tesla engineers know about LEDs.

jordanrichard | July 8, 2015

For those saying that Xenon lights are so "yesterday". There are a lot of brand new 2015 cars on the road that still have standard halogen headlights.

Iowa92x | July 8, 2015

Yes, xenon and halogen no longer belong. LED.

DonS | July 11, 2015

I'm betting new headlights are one of those things Elon mentioned that we won't know about until the car is released.

carlgo2 | July 11, 2015

Dimming headlights found on most cars today are in practice only brighter versions of those $3.95 lights we used to see at grocery stores. Selected illumination laser is the future, but LEDs are the best available now and if they turn and have auto dimming, that is about what we can expect for now. Anything less than that on a Tesla would be puzzling.

Thank you for the clarification of LASER lights.

It may be a better description to say "LASER Flourescent" if they use phosphors.

grant10k | July 15, 2015

@holidayday

Probably, but since there aren't any headlights that use lasers more directly, I don't think it's too much of a misnomer to just call them laser headlights. Same reason we don't call plasma TVs "Plasma Florescent" TVs.
