The lower area of both my car headlamps have corroded reflectors (see images). These are standard 2015 5.3/4 glass headlamps.
I do drive the car in wet weather. How common is this issue for other wet weather drivers?
I plan on replacing the headlamps with these from Caterham https://caterhamparts.co.uk/headlights/1932-headlamp-glass-rhd-2015-onwards.html
Any tips to prevent corrosion from occurring again, or at least slow it down?
