My brand new Puma was in the garage today for the condensation in the lights, it’s really bad and stays for 2 and 3 days at a time. The garage have said that this is acceptable but it is not acceptable to me. Has anyone had this problem resolved?

HEADLAMPS – FREQUENTLY ASKED QUESTIONS

Why is there condensation in the headlamps?
Headlamps have vents to accommodate normal changes in air pressure. Condensation can be a natural by-product of this design. When moist air enters the lamp assembly through the vents, there is a possibility that condensation can occur when the temperature is cold. When normal condensation occurs, a fine mist can form on the interior of the lens. The fine mist eventually clears and exits through the vents during normal operation.

How much condensation is acceptable?
The presence of a fine mist, for example no streaks, drip marks or large droplets. A fine mist covers less than 50% of the lens.How long may it take for the acceptable condensation to be cleared? Clearing time may take as long as 48 hours under dry weather conditions.

How much condensation is unacceptable?
A water puddle inside the lamp. Streaks, drip marks or large droplets present on the interior of the lens.

What should I do if unacceptable condensation is present?
Have your vehicle checked as soon as possible.

Just noticed my n/s one is quite bad today. Will keep an eye on it over the next few days.

I get it a bit in front and rears, doesn’t last long and thought it was because they don’t heat up like halogen which clears the lenses straight away.

Could be. As long as they don’t puddle I’ll be ok with them.

When I took delivery of my Puma 14 months ago, I remarked to the salesman that there was a lot of condensation in the rear light clusters. After that, I forgot all about it. Fourteen months on, I noticed today that there's a lot of condensation in the rear light clusters. I've kind of got used to seeing it on cold days.

Should I report this? Would fixing it potentially cause worse problems?
