clio headlight protectors

[ADY 554D]

anyone know how much these cost?
i have a set on my 182 (on when i bought it)
and dont know if to leave them on (look a bit girly but could save my lovely xenon's)
or ebay them and spend the money on petrol (trying to avoid any great big stones hurtling there way towards my lights!!).
so what would you do ?
on or off

On.

On if I were you.

I've been lucky with this car, but my old clio needed two new headlights.
