2006 Yaris headlights

Recommended Posts

Hi everyone, I have an issue with my 2006 yaris headlights, the bulbs are ok it's just the actual unit itself. I also have standard halogen bulbs, no LED, no projectors. 

these are the headlights for clarification:  

https://www.google.com/search?q=2006+halogen+yaris&rlz=1C1CHZL_enGB752GB752&source=lnms&tbm=isch&sa=X&ved=0ahUKEwj43KWJ4cjkAhUOiFwKHXzfBiwQ_AUIEygC&biw=1280&bih=578#imgrc=99Gi_IRICkTaIM:

Both the headlight units have a yellow tint to them but its on the inside, (I think it's called oxidation?), and my headlights are literally useless without using fullbeam.

Question 1) Can i clean this yellow tint?

Question 2) if not, then I need to order 2 replacement units, anyone know the best place to get them from? I've seen prices vary from £50-£100, hoping to get them around the 50 mark.

Question 3) I don't want to stick with the original bulbs, are there any bulbs I should upgrade to, or will a couple of replacement bulbs do the trick?

Are you sure the yellow "tint" is on the inside?  A lot of modern cars have plastic covers with a surface treatment which degrades over the years to make the headlamps look yellow.  This degraded film can be removed with a bit of DIY/elbow grease, and you should be able to find a few threads about this on the Forum.

I have the same issue with my 2006 Mk2. They all go like it, and its sun damage and oxidation of the outside of the plastic lens. They start deteriorating from the tops of the lens, and it progresses downwards over time to affect the whole headlight lens. The Mk1 models also do it, as my last car had the same issue.

I find that using Meguiars Plast RX which you can get from Halfords, and plenty of rubbing and buffing can improve the lens, but to do it properly a buffing pad on an electiic drill is better.

If the deterioration of the lens is bad enough, the car can fail its MOT, but usually, light deterioration and fogging of the lens will get an advisory.

Without wishing to endorse any products, there are many Youtube videos on how to polish this out using kits which are readily available. It does look quite daunting initially because fine grit abrasive is used first, then gradually reduced to a polish.😨

I haven't yet had the need but will look into these when and if the time comes. I'm sure it will because my car is kept outside and has the full sun (when it appears!) from mid morning to evening. I'm glad of that sometimes because it evaprorates the damn internal misting which occurs occasionally. No doubt no sun will only slow the deterioration.

    1. 1. If you were to consider buying a Hybrid model over 5 years old, would you be worried about the reliability of the Hybrid system?


      • Not really as Hybrid systems are always reliable
      • Not if it had a Manufacturers Warranty on the Hybrid system
      • I would not buy a Hybrid model over 5 years old
