Moisture in Rear Lights

[gazza57]

Hi All,

Recently had an inner rear left light cluster ping up as defective, changed it out as LED lights are NOT replaceable.
£209 + VAT..ouch
Three days later right hand inner did the same another £209 +VAT

A month on and the new ones are misting up, found out there some water in the n/s enclosure pod under a box of electronics which is thankfully dry.
Looks like a failed seal in the rear window quarterlight, will be fixed next Monday

Further to this discovered it was not the window seal to blame, there are rubber seals which sit around the fixings that hold the rear bumper, these had perished allowing water to leak in and collect in a puddle about 1cm deep, hence moisture laden atmosphere and problems.
If you get this suggest removing the rear bumper and replacing all seals both sides, and check both n/s and o/s rear pods are dry.
Failure to do this will wreck the rear lights which have electronics in them and are £500+ per side.
