Has anyone else experienced condensation forming in the rear lights (2015 hatch vRS)? I noticed some in my NSR lamp after washing the car yesterday, predominantly in the reverse section, but also in the top section (brake/side light LED?)

If so, whats the easiest cure apart from replacement ?- typically the warranty ran out in September last year.....

If I were you, I'd take the cluster off and fully dry it out.

 

Then check the lamp for any cracks/damage and inspect the seal.

 

Assuming it's all fine, refit the cluster but make sure the wiring sits inside the car body and isn't preventing the seal from making a good connection with the car body.
