UPDATE:
Tonight I had occasion to drive in the dark again.
my headlamps were seemingly dim compared to other cars on the road.
so I pulled over and as luck would have it, I had a pack of water based wet wipes in the boot. I was able to clean the headlamps and fog/cornering lam p units.
Then back on the road. an improvement but still not enough.
my car has combination lights in the bumper which are cornering light AND f oglights.
when below a certain speed and you are cornering, one of them lights up aut omatically and turns off automatically when you are back to travelling stra ight.
Equally when foggy, the fog switch can be turned on and what was the pair o f cornering lights then become a pair of foglights.
On a hunch, I turned my front foglights on tonight. they make a massive dif ference as I can now pick out both sides of the road and they do not appear to dazzle other drivers.
whats the law regarding having a pair of cornering lights permanently on as opposed to having a pair of foglights on when it is not foggy?
as for cataracts, I am only 47, I am a bit young to have cataracts and my l ast eye sight test did not reveal any cataracts. I must admit that when loo king at light directly i can see scattered light around the light source it self almost like a light haze....
