Cloudy headlamps

Oct 26, 2013 24 Replies

Has anyone found a successful way to polish out the 'haze' on plastic headlights? There are lots of suggestions involving elbow-grease and toothpast on YouTube, but I tried that and it may have made a slight difference or it may just have been wishful thinking. Brasso was not much better, but I think T-Cut was, but only marginally. There are scary videos using fine grade abrasive kits on YouTube. My garage said that the showroom next door uses T-cut and an electric polisher, but I don't have an electric polisher and I believe conventional drills with mop-discs can be too fast. Any ideas?


Any such polishing is hard work by hand. Since it's similar to cutting back car paint, Farecla is the best for that and comes in more than one grade - although you'd likely have to go to a paint supplier to get the coarser stuff. Halfords do the common one.

Have you checked if you can buy new lenses on their own? Ebay might be a source - they're unlikely to be a dealer spare, but check anyway.

430 for a pair - hence.............

I got something called Greygate Plastic Polish from CPC a while ago, which works on mine. It warns not to use on Cellulose Acetate, for which they have an alternative product according to the label. I don't think it would work for anything other than the finest scratches.

That's presumably the complete units? It is possible to buy lenses on their own for some cars.

After a pheasant attacked my Renault Laguna headlamp assembly, smashing it comprehensively, I bought a complete used working unit on the internet for £25. Since a new unit is in the hundreds, I think it was a good deal.

Lucky you. I did look.

Get down your local car breaker. They still exist

"They" being? The OP hasn't named the vehicle.

Stick in your reg no and any parts available will be listed.

On my previous Fiesta, the glass easily unclipped from the unit (I stuck it in the dishwasher a few times). However, it was not available separately - you had to buy the whole unit. You could get a cheaper version without the motorised level adjust, and either just unclip the glass front, or use the whole new unit and move the motor across.

I was under the impression it was a change in the actual material opacity itself due to UV that was the real problem in most instances. Brian

Indeed and since it is a 2004 Mitsubishi Space Star that was only made for a few years, used parts are hard to come by.

With at least some makes, the actual 'glass' may be available in other countries than the UK. Which can take a bit of finding.

A forum or car club for your particular model would be a good start for info.

I looked at that site and some of the bits are as expensive as the main dealer, some are more expensive (for a sample of one car).

That might explain why some cars have left hand drive light patterns on one light.

The most common reason is that some people just can't fit a bulb correctly. Maybe a part P for car electrics?

It would depend on whether it has a fresnel lens as part of it or is just plain. Thought that would be too obvious to state.
