I had assumed all euro-headlights were made of tempered glass, with
all the talk of using 80- 100 watt bulbs. Wouldn't high wattage bulbs
melt or distort the plastic lens? My replacement lens just arrived,
box marked Bosch, is plastic ...or lexan. what should it be glass
or plastic?.........I never really checked

The stock wattage (60 watts, I think) is more than adequate unless you
intend to be doing brain surgery on the asphalt in front of your car. I
recently converted my 300D to Bosch Euros with the stock bulbs and I'm
very satisfied. Higher wattage risks blinding on-coming traffic, which
you'd like to avoid, even if you'd get a good look at your assailant
before you were struck.

For what car? Was the old one glass?

OK, but what about the contacts? How often did you replace them?

Yes, the BOSCH euro-headlights ordered from Bekkers, and installed
years ago are glass, and almost 1/2 inch thick . The lens is broken in
an upside down Y pattern, but still in place in the frame. The
car is '92 190E, the lens has these numbers 023444R19 BOSCH HCR

You're not driving the car, right? You'll buger up the reflector if you do.
I've never heard of plastic euroglass replacements. Sounds dicey.

Where did you buy the lens from? Does the replacement part have Bosch
trademark stamped on it? Part number that match the box?

Comparing plastic to lexan is like comparing cotton to kevlar. Lexan is
almost totally unbreakable.

Hello,

And totally vulnerable to the UV and infrared radiation. Come to Arizona
and the America West. You'll see many, many, many, many, many, many
'jaundiced' headlamps. Once they're yellowed, they're done for unless
you have intricate procedure of polishing off the thin yellow film.
I've managed to break the Ford Taurus headlamp lense with hammer one
bored night. Ah, it's not indestructible as Ford claims them to be. I've
seen many Ford vehicles with Lexan headlamps broken or cracked after the
collision.
