I was browsing through some old pics and came across my old Bosch lenses:



I noticed the lens pattern is identical to the Bosch lenses on the Euro assemblies currently on my car:



However, I also noticed that my 190E, which has Hella Euro lenses and what I observed to have "better" foreground lighting, has additional fluting above center line of the lens face that looks like a "secondary cutoff". This secondary cutoff throws additional light on the foreground.



So this got me curious - are all Bosch square Euro lenses the same? How about in comparison to the Hellas? Or in comparison to the round type W123 Euro lights?

Got some H4's but haven't converted yet. Mine look close to the ones they use in the old Cobra & Miata conversons!

Tell me if I'm wrong but the lens pattern is different depending on what side of the road the donor car drove on. German lens would be the choice for us while English and African, Japanese lens' would direct the light to the wrong road side.

^^^^ this...




So yes? I'm correct?
Yes you are correct. In the picture I posted, the lenses are both for the right side. But look at the "half of bowtie" shape in the middle of the main pattern. The upper lense is a "left hand drive" pattern with the bowtie triangle pattern flaring towards the left side of the car. The lower lense is a "right hand drive" pattern with the bowtie triangle pattern flaring out to the right side of the car.

The W124 Bosch Euro lights on my mother's 300TE looks similar in design to the W201 Hella Euro lights on my 190E.

Side by side for comparison, left/driver side assembly only:

W123 Bosch


W201 Hella


W124 Bosch

Pat, here in the US we can order Bosch euro lenses that have a different USA specific beam pattern that are not "comm-blocked" at the dealer. However the the euro "Hella" lenses are comm-blocked while having the normal euro/german pattern.

To get the comm-blocked ones you have to have a euro vin.

Garrett,

Are you saying there is a US DOT approved version of the Euro lenses?
Sounds like he is saying that.... and sounds like we can only order DOT lenses if we do not have a Euro VIN.



Adding to the topic...

W126 Bosch lens.

Nothing on the boxing or lenses to saying so .....your guess is as good as mine.
