Mk4 Headlights

[EMPTY HEAD]

hi good people plz can you help i have a jap import mk4 and it has bad yellowing plastic headlights (mot fail)

what can i do about it ? can it be cleaned ?

i have tried taking it out and pouring boiling water and washing up liquid into it but it made no differance !

the toyota garage wants about £300 for a new pair and could not tell me if they were glass or plastic !

can i fit either or do i have to fit plastic ?

and where could i get new or good clean pair cheap ? seeing how bad those have gone i would prefer glass

many many thanks inadvance

Glass or plastic will fit....

However it shouldn't be an MOT fail!!!!! I'd take it somewhere else!!!

The yellowing is caused by oxidisation... many people swear by various methods of cleaning it off (from abrasive polish to corrosive cleaners that "burn" it of!!!)

I would get onto find a part and try and get some UK sped glas ones

I know where to get new UK spec glass lights for £240 as well. ;)

Or if you fancy doing it yourself, there's a pretty good guide here:

I have a spare offside headlight in my shed that's slightly yellow - available for a small fee - if you want to practise on it?

There are some clips, but they're obvious ones. There's a walkthrough on the mkiv forum:

i like the first link got me wondering where i put my heat gun

but the second 1 got me wondering where i might get some glass 1's cheap if all goes wrong

best bet is check your local breakers. You remove the bulbs and all metal parts and bake in oven until the plastic rubber seal starts to melt then you pull the lights apart.....Before you do this get some G3 and BUFF the outer light 80% of the time it works.... If not stick erm in the oven...dead easy to do.....If you need DIY instructions let me know. Also you can facelift the lights at the same time...Just paint the inners matt black :-)

OMG mrboost, you got 450 RWHP with only the second cat removed? What the hell kinda EGTs are you getting? Must be running 1.3 bar to get that power - on stock turbos!!!!

[/hijack] sorry.

i live in the uk and went to Halfords (car parts shop) for window sealer which i got but they said they do not do plastic cleaners just cleaners general

i tried cleaning the out side of the lense with Cillit Bang

and when it was wet with cillit bang it looked great but when it dried out it looked bad again, i have now polished it with vaselin and it looks good again but this is not a solution, any idea's plz plz

polish the inside and outside of the glass with tcut.

put the light in the oven the heat them up to prize apart.

when putting back together make sure everything is pristine, place headlight parts in oven again and use large amounts of silicon to help rejoin the 2 parts
