R3 how to remove water from rear lights?

Post by rickp »

Hi all,
Just wondering if anybody has any advice on removing the moisture/water from within the R3 rear light units?

I had a slight fail last night after fitting a new Mazda gasket and it raining last night... I guess I didn't quite have it tight enough...

Looking at the bulb holes, it looks like they have no route to get site too the outside lens area... As I tried to see if a cool hair dryer may help to evaporate it...

I have moisture and water in both rear light clusters and need a quick method to get them dried up... As I don't have a garage and the car is parked on the street.

Thanks in advance and seasons greetings to all :lol:

A cool hairdryer should be safe enough, though on hot it would cause damage.

Silicon grease is safe to use on the gasket to help it seal.
Some have used Vaseline, which also works but may attack the foam.

Thanks Dave... Would you say trying to use the hair dryer through the bulb holes, or on the outside of the lenses to warm them up from outside would work best?

You'd struggle to get warmth through from the outside without potentially damaging the plastic so cool airflow through the bulb holes is your best bet.

You could try putting the unit in the airing cupboard*, or on a radiator on top of a folded towel.

*called "the hot press" here in NI :roll:

You may get away without drying it once the seals properly seated. I dried most of mine out in the conservatory in summer but like you didn't fully seat first time. After washing the car it got a bit wet again. I didn't really want to dry them again (think the weather had changed but can't quite remember) so I retightened it without drying it out again to see if it's clear itself and the residual evaporated away over time. As far as I can tell its not sealed to the interior of the car so it'll still vent into the cabin over time. Given I did this in summer the weather was a on my side so winter may take a while longer (if at all).
