The Calibra marketing brochure was very proud of the Calibra's high-tech kick-@arse lights.
...maybe when they were new they were fine (for the limited frontal area), but most Calibras I've seen have very sorry lights at night.
Changing bulbs doesn't help much, as the wiring is crap and the reflectors have lost their shine for ever (only a few microns thick!)
It's best to get the whole unit out, don't try to squeeze the glass bit out. The seal won't go back properly and you don't want road grit inside.
3 8mm screws and they're out, then 8 clips hold the glass together with the rest:
The connectors could do with some contact cleaner/enhancer. Oh yeah...
don't forget those hanging from the car, too
This will help reduce the ridiculous voltage drop across the terminals (Kingsley measured 2Volts missing, gee...)
The glass units need a good clean inside out
This won't get rid of all the imperfections, but it helps.
Use Brasso for the outer surface, it skims off a thin layer of pitted glass (every little helps)
I'd only use one of these 'microthead' cloths for *lightly* wiping the reflectors. They're wafer-thin, and you could easily do more damage than good.
Mine had a goldfish inside, broken glass too!
I guess this particular piece of high-tech design didn't age very gracefully, did it? lmao lmao lmao
Oh well, at least they look good...
