Omega headlight adjusters

[MonzaGSE]

Changed a headlight adjuster last night on a post 98 halogen hella lamp. Classic case of adjuster broken in half. Took an adjuster from an old broken Depo lamp. The only part on the depo lamp that has better quality than the Hella original in my opinion. All went well. But as i took everything apart i found that i would need to keep the white plastic clip from the hella lamp that grabs on to the reflector. When trying to get the remnants of the black plastic adjuster with the ball on it out from its seat in the white clip the whole black adjuster just basically pulverised in my hands. So i got the parts i needed to rebuild the lamp but i was very surprised of just how brittle the original adjuster was. Where they this crappy from new or is it something that happens with age and heat?

probably a combination of materials used,age and heat. much the same as on varoius other vauxhall headlamps of the era or older.cavs ,manta carlton,senator,monza to name but a few !
