The blackhole of Thai roads

[mraitchison]

A few years back I was having a moan to an old friend about why he roads in Thailand appeared to suck up my car headlights light output making visibility poor. He told me, as an ex road engineer, that the roads in Thailand use little to no limestone chips in them, which in the UK increase the reflective nature of the road surface and allow lights to be more effective.

I was driving around last night, and remembered this conversation, whilst bemoaning the visibility on the road

Anybody know if it is true or not?

Don't know about the limestone, but what I can't stand is that Thais never adjust their lights.

So when driving in the night, their lights blind you and you have no visibility at all.

You can solve this with 80% tint + even brighter bulbs.

Interesting, I have driven my car here on halogen lights, and then converted to xenon and found that both were as useless as each other on the roads. Well for me, anyway.

I am now back to halogen, may be I should go up from 55w.
