Why don't tail lights cloud and oxidize?

Some will remember the period when a certain sort of halogen desk lamp was stylish. My dad bought me one.



Some of those were built with a thick plate of greenish glass down below the bulb, to absorb the UV from the halogen bulb itself. Mine did not have the glass plate.

I used to wonder why my forehead always felt sunburned if I had been working a long time at my desk.

 

If flexible glass (think of the molecule thick super glass) can be made you could just encapsulate the plastic in an extremely thin layer of glass, virtually stopping oxidation (remember that plastic is a mix of reactive compounds and may still eventually haze from the light and base chemicals reaction )

 

My sealed beams had a simple angled cover over them I could remove

 

Even with those areo headlights, the slipperiest cars are still dozing a ton of air.

Not that anyone that fuels an ICE would notice or care as evidenced by the auto industries claims of tremendous gains in mpg in the last 2 decades and the general public believing it.

 

Whatever aero advantages the headlights have these days, they're maybe cancelled out by the (faux) "air intake ports" at the fog lights (or blanks, for levels without fogs)??

 

I do have a $5 set of 4 halogens that came packaged in ziplock plastic bags and have a blue coating or tint to them.
The pics show a pair of different sized and socketed halogens without any coating or tint.
so yes and no on both accounts from what I'm seeing, which as always is only a very small part of the big picture.

 

In Wisconsin...

Registration and title for a hybrid $555
Registration and title for an EV $630

My Cobalt costs $41 in gas tax annually, the public probably notices the discrepancy.

 

I thought they had to do that because we Pri and EV users weren’t paying our fair share for road repairs because our vehicles weren’t contributing much with the gas tax.
No?
