Iíve had this odd idea rattling around in my head for a while now and thought I should give it a try.
Itís a long term experiment as results will be difficult to measure but ultimately Iíve got nothing to loose.

Now the ulez zone has swallowed up my workplace I will occasionally go to work in my only ulez compatible car, the Berlina. Mostly weekends and when itís too cold to swing my leg over the motorbike.

Having rebuilt the headlights last year due to water ingress causing the reflector bowls to corrode, Iíd like to prolong it happening again. Itís a problem weíve all seen and expensive to fix (re Chroming or replacement).

I donít know if this has been done before so I come up with this is odd idea.
Why not fit dessicant dehumidifiers?

A couple of motorbike brake fluid reservoirs, a few bits of silicone tubing and some dessicant.
As the headlight heats up it should breathe out via the vented dessicant towers taking with it moisture and when it cools down it breathes back dried air. If the dessicant changes colour anytime soon then I will at least know something is going on.

Simples eh?
Will it work? No idea.
But Iíve got to try something as re Chroming headlight bowls is an expensive place I donít want to revisit.
