Hi,

Just wondering how many of you have[like my Alphard]have h/light lens that are turning yellow/opaque due to being exposed in Japan to v.strong sunlight. MOT Testers are beginning put the fact on Test Certificates as an Advisory.Before the MOT last year I used a product which was a spray-on foam which was then buffed to give a clear lens again. I will do this again just before the test this year to ensure a pass.

The product I used is: ROADSIDE RES Q! CLEAR LENS SINGLE STEP Headlamp Restoration. It is a USA Product which was all over Ebay at the time. There are other types available.

I have used this product on different plastic lens on different vehicles which work well, but each year I have done another buff.

Hi, Ive used toothpaste and "t cut" in the past, It does work but takes an age.

I use lens cleaner for headlights then clear laquer with uv protection. still have to do it every year but it's better than every 6 months.

If you can afford them I renewed mine on 2007 2.4 alphard via a company Nengun about £600 each with post and taxes . It was worth it for me . You’ll need the OEM numbers and I was worried that I had ordered correctly. You could try ordering via your local Toyota dealer and maybe get them for their price around £400 each Good luck 

I find that the headlamps still produce v.good light even though the lens v.slightly  yellowed. The cleaner I use only takes about 5mins to clean each h/lamp, so no real problem once a year. The units are so expensive and as my night driving is a minute amount of time,I'll keep up the annual clean.

I used the autoglym kit about 8 months ago, still looking well today took about 20min per light as there was a few stages to complete.
