Fog in rear lights

[tomred1]

I have some water in the rear lights, I was just wondering will this eventually evaporate? or should i do something about it?
its a opel astra 05

Definately wont evaporate at this time of the year. Theres either a hole/crack/ damaged seal etc or you recently removed the lens. If theres a hole/crack the water will continue to get into light.
You need to prevent anymore water getting in. Or drill a hole near the bottom to let the water out.

If it hasn't been damaged take it back to Opel. Warranty still applies afaik.
