In episode 6 of the BMW E30 325i restoration project, I restore the headlights.
Again, these are something I have already restored before starting YT. So I bought some from eBay for the channel thinking they were pre-facelift metal frames, not facelift plastic frames. But none the less, it was still a fun restoration.

Firstly I dismantled the lights completely. As most of the mounts and adjusters hadn't been moved in years, it was quite tricking getting everything apart compared to putting it back together. Once apart, I got straight to blasting the surrounding rings to remove all the rust and old paint. I then buffed them on the buffing wheel and hammered them straight as some were bent. I then etched, primed, filled, primed, painted and lacquered the rings.
The main headlight housings only need a clean and a small amount of rust removal. When I was preparing for this project, I forgot about that fact I might need to touch up the backs of the lights. I'm going to get some paint and do that in the near future.
Once everything was clean and rust free, I set about restoring the lenses. I had some trouble to begin with as the kit I got was for plastic headlights. The sandpaper did nothing to the glass. I then swapped the paper supplied for some aluminum oxide paper and that cut straight through the top layer.
After going over with 320, 600, 1000 grit sandpaper I then used some water with a 3000 grit 3M pad before moving to the orange sponge pad with cutting compound. I was happy with the ends results but I would have to do a lot more work to get rid of the chips. I could have also lacquered the lenses and may still do this.
It was then a matter of reassembling the headlights and giving them a test as I hadn't done so before then. All of the lights worked and are nice and bright. Restoration complete.

  • water application in small constand flow using belt sand papers of decreasing grades is the only way to do this properly. Final polishing is achieved with cork and water.

  • The white stuff is from the vertical paint lines that were in the headlights when they were new.

  • Bosch is not the best choice. We must put Hella. They glow better by 20-30% Diffuser (glass) is better to use Hella. The most important thing in the headlights is the reflector. It is better to replace it with used one, but in good condition. Most often reflectors fade from the use of lamps, high power.

  • Nice work! The inside looks Dull still. Use some white birdsand, then waltz and shake it around on the glass inside of the lamp... That will do the trick for most dull e30 headlights

  • Hey great work there! I was wondering why is there an aim control unit only on one pair of headlight? i have a problem with both side on my car. it seems that the gears that level the height of the lights are somehow broken or worn (kind like the odometer gears) , and as a results they immediately go back to the lowest setting. did you figure this out?

  • Very nice. But you didn't show the most important part, the reflectors (the mirrors) inside. If the reflective is eaten up your light will be crap. Are the reflectors metal or plastic?

  • I might gues that white stuff is the same kind of heat paste that is used inside electronics to protect them against heat which in this case, comes from the light bulbs. Maybe because they have so little space compared to ones used in todays cars.👍🏻👍🏻

  • The white stuff on the inside is removable, just use some brick sand that u use for making cement for bricks. use that sand in combination with some water, put is in the headlight, and shake it for like 15 minutes. wash it out and let it dry for like 2 hours. when dry your headlights are clean and 100% clear. i do this for years now, please make sure to test this method, and let me know about the result.

  • How couldn't you find stock headlight lenses or reflectors? There aso many of them. It's only hard to get yellow hellas or black boschs. Or not even hard, but expensive. The normal headlights are cheap and available, even single parts of them.

Brilliant job man :) And I thought I was meticulous with rebuilds ... christ man, you're making the rest of us look bad :) Seriously though - great job. Unparalleled attention to detail, craftsmanship, mechanical understanding, and style. Nicely done.
