[Shotimes] Yellow Headlights

[Donald Mallinson]

I wish we had a for-sure reason why some headlights turn 
yellow and others do not.  The lenses on my '89 are still 
original, and are like new other than the sand blasting that 
puts tiny chips in them.

I have never had headlights yellow on me, but my son's '95 
are both going bad.

I don't use car wax on my lights.  I DO use Meguiar's 
plastic cleaner and other products designed for plastic and 
they and my tailights both look great on all my cars/trucks, 
at least for the miles.

I suspect that car wax on the lights, and not keeping them 
clean to begin with has some effect.  Keeping after tham 
from day one with proper cleaners/polish will keep them from 
yellowing.
