Laser Light Bar available when and what price?

[CYBEAST]

that 48v power is only available when you turn it on from the screen. So even if you can find a 48V light bar and get it installed, Tesla still dictates when you can use it thru software to comply with the laws.

What do you guess the cost will be of the Tesla light bar?

Which also likely means if you don't get the tesla light bar, your vehicle won't have the button on the touchscreen. Just like how they are now offering biohazard mode to older model Y's, but they have to install it because they have to change your vin in the system to include the option and push an update. If you have the parts yourself, you can physically put it together, but the option still won't exist in the touchscreen. See below, button seems to exist in an AWD model with no light bar attached/ordered.

I do think there's a live 48v hookup somewhere, if you wanted to run a physical switch somewhere, but it doesn't run up to the roof.

my guess is between $900 and $1,500, including the cost of installation at a service center. I think that's how you will pick up this light bar. They probably won't ship it to you directly.

Very reasonable answer. I think $2-3k. All the oem accessories and pretty expensive. The plastic crossbars are $800 and the $100 ramp is $400. So I’m going with twice what you guess. lol

The button is there on the screen even for the AWD CTs. Tsport tested it too.

Well that's good. Unexpected for tesla, but good. I'll go back and edit

Works now until the oem light bar is released ?

Nothing is impossible with tesla (like how they are removing "roll" modes from new vehicles), but this isn't one that I'd expect exists now and would be removed later. Time will tell I guess.

Remember we saw the power wires. They r 48 volts. The 2 power wires hidden are 48 volts. NOT 12.

 

[CYBEAST]

Interesting that aside from the 48 volt red wire, there is a constant 10 volts coming out of the green wire whether the CT is on or off.

Lasers would make a terrible light. Lasers are monochromatic so red green and blue lasers are needed to make white light. Lens would be needed to spread the point light source to a broader beam. They are also less efficient than white light LED’s. I think “laser” is just a branding name.

Look up Laser Excited Phosphor (or LEP). It's a very common practice now to have diodes be ~fluorescent, and excited with a blue light source to produce a white or green light. In this case, it just happens to be a phosphor that's backlit by a laser instead of an led.

White LEP modules definitely exist, and are already being used in flashlights. They produce a very tight beam, that is very bright (but very small in diameter vs the distance from the light). A light bar would be a very good use for them, because you can put many of them next to each other, and make a very tightly controlled strip of bright light that shines very far.

I'd guess it will operate in Baja Mode (at least logically it should) and that's more than 25mph or it's the lamest Baja mode there is....so I'd assume it works in any off-road mode, speed unlimited - aka where it's legal to use it and useful to use it! My 2c, could be wrong, just speculation.

this is correct.

It’ll be available soon.

Once the laser beam hits the phosphorus, it diffuses from the rescattering of the light. If the laser diode is more efficient than a UV LED or blue LED, it would make sense to use laser. Not sure that is true.

It's a tighter beam than you can achieve with an led, resulting in a brighter spot (but much narrower). The light source is smaller than even the tightest of leds (Osram W1/W2 emitters are the closest led equivalent), resulting in a significantly narrower beam.
