Yes it still is a lens design over 20 years old. A lot is changed today....
I’m just looking for a decent set up, I can honestly say mine has the worst head lights I’ve ever had in a car beside a Peugeot 405 I had where all the chrome had burnt off on the inside...the head lamps them self are like mint crystal clear so I’m struggling to get my head around why they are so bad.My current favourites are ring xenon star 4400k, personally because they are a economic white bulb, without the blue of the so called xenon effect bulbs, nor the yellow of traditional bulbs.
I’ve tried many bulbs over the years, and we are I think expecting too much from traditional halogen in comparison to modern xenon or lead lamps
I’ve messaged him about it very friendly, blows your mind abit with what he can do to them tbh.If you have a spare set you could send it to this guy who puts led projectors into them have a look at these
