HID Lamps; Your opinions and experience

As I get older, and I find myself needing more and more light as the
lenses in my eye darken, I have noticed a definite need for more light
on night landings. My eye doc has recommended waiting a while on the
cataract surgery, as they are not so bad yet. Given that, I think
having a better view of the runway at night might save me my aircraft
and maybe my life if I were to install one. HID lamps seem to be the
cat's meow for this, but some things I have read have said they are
not worth the money. Some have said they are fantastic. I have never
seen a pair from behind the yoke as it is, and would like the opinions
of anyone that might have them in their airplane.
Also, what about installation approval issues?

Bud
