Purple/blue headlight

It looks cool, but I’m pretty sure it’s illegal in Texas to run color headlights. So I’m trying to flip back to my normal headlight. Buuuut I don’t know what caused this. I was literally at dinner and walked out to the change. Super confused.
The headlights have various lenses and mirrors to create the beam pattern from the point light sources. Some of these are articulated so the headlights can be aimed and switched between high and low beam patterns. So if I had to guess some element of this system has gotten itself out of alignment in a manner that’s refracting the light and you’re getting the blue end of the spectrum.
Quite a nifty fault.

White LEDs are commonly a type of LED called Blue Pump or Phosphor Converted LEDs. They emit blue light that is then converted to white light by a phosphor.

In your case, it appears that the phosphor for one of your LEDs has failed, resulting in the emission of blue light. You'll need to make a service appointment and Tesla will need to replace your entire headlight fixture.
A similar problem is happening to a number of street lights around the country. Google "purple street lights" and you'll find more information.
Here's one example: Have you noticed the purple streetlights around the Baltimore area? They’re not for the Ravens.

What Is a Blue-pump LED? | Global Lighting Forum
A blue-pump LED is a phosphor-conversion white LED package which uses a blue LED chip (InGaN die) to pump light into a wavelength converting element (down-converter). The wavelength converting element contains one or more conversion phosphors. It absorbs blue photons form LEDs and produces...
Design of highly efficient phosphor-converted white light-emitting diodes with color rendering indices (R1 − R15) ≥ 95 for artificial lighting - Scientific Reports
Phosphor-converted white light-emitting diodes (pc-WLEDs) are excellent energy-efficient light sources for artificial lighting applications. One goal of artificial lighting is to make objects/images look natural – as they look under the sunlight. The ability of a light source to accurately...
