Headlight restoration
Discussion
Is it economical? If you attempted it, how long did it take you?
My headlights are relatively smooth, but have heavy browning (oxidisation?)
New Peugeot headlight with a motor costs £103, and I'm trying to decide is it worth restoring, or should I buy new? Car is about 12 years old. Some restoration kits cost £40. Is there any market for road-legal but oxidised headlights? The MOT has always passed without any advisories on the headlights.
Thanks for any advice!
cheers,
Simon.

You don't need a kit, but to do it properly do you need to remove the light unit and use either a foam pad on a drill or a polisher.
Start with wet and dry paper, then a coarse and then fine compound, finish with a coat of UV lacquer....
They can come up like new with enough work. Maybe an hour on each at least.
Factor in the costs and time... maybe buy new.

I used this kit: https://www.amazon.co.uk/Autoglym-Headlight-Restor...
It has all you need and I used a cordless drill for the power. Just follow the instructions carefully and whilst your headlights won't be 'showroom' afterwards they should be much better.

Its not hard to get them back to looking great as Tony states, however once you start, be aware that its a process that you will have to repeat.
You can either sand them back and then work finer and finer grit and end by polishing, but they will fade again over 6-12 months from the UV once you start down this road. Alternatively you can clear coat them instead of polishing which gives UV protection and a longer term finish, but lacquer doesn't like sticking to plastic especially when its sanded so fine before spraying, so eventually it will fail, but overall its going to improve them drastically and save you a load of money on new ones as long as you accept that you will have to do them again in a year or two.

Solvol autosol or Peek, even T Cut, all will do the job acceptably without having to remove the lights, 10 minutes of elbow grease a side will see a marked improvement, of the metal polishes White Diamond leaves a protective coating of some sort but its expensive stuff so i wouldn't necessarily buy it just for this purpose.
A coat or three with a decent anti UV wax polish afterwards will help keep them bright, but inevitably they'll dull over again so a couple of minutes cutting back every 6 months or so will be needed.

A new genuine part headlamp, with either fittings for the old motor or indeed a new motor, @ £103 incl tax each is amazingly cheap these days, but its still well over £200 plus snapped off fittings etc compared to 1/2 an hour polishing and maybe £8 a tin/tube of metal polish, no contest in my humble.
Wish mine were that cheap for the Prado, polishing helps keep them serviceable but after 20 years of weathering some crazing is visible deep inside the plastic lenses which would be impossible to polish out without ending up with wafer thin lenses.
Can get aftermarket (Depo) with fittings for swapping over the motors for around £125 each, new OE approaching £400 each, others on the Landcruiser forums have Depo aftermarket light units fitted for many years which fit perfectly and are lasting as well as OE, mine are not bad enough yet to warrant changing though and its a bumper off job anyway so definately a summer performance.
This isn't always the case with aftermarket, the original headlights on our Mk1 Mitsi Outlander crazed really badly @ 5 years, no help from the maker (such lack of interest no doubt adding to their lack of new car sales and eventual disappearance from GB) with new units some £350 each which quite frankly i wasn't prepared to pay for such an overall disappointing and thirsty vehicle, so bought some aftermarket units which were hells own job to find which fitted basically where they touched...the saving grace for the Outlander was its handling in poor conditions was every bit as sure footed as any of our Subarus maybe even better.
