.... in todays world Halogen isn't really cutting it. ...
Why not? Are the nights darker than they used to be? Are skippy and bambi less reflective than they used to be?
I can understand the need to see further if you are driving faster, and yes modern cars can go faster, but speed limits haven't got any higher so I see no sensible argument in that regard (in fact, I'd be pretty confident in saying there haven't been any increases in speed limit, road upgrade and bypasses etc aside). Even street lighting is constantly being improved (and that too round here is too bright when driving!) Yes, being able to see where you are going is a great safety feature, but it seems super bright lights are only safer for those sitting behind them, and a damn site less so for everyone else.
Dip beam is all well and good being low down and a sharp cut off so as not to dazzle. This doesn't matter one dot when going over crests of hills and over bumps etc. Yes this affects all headlights whatever their light source, but super bright LED and HID lamps are a lot more noticeable here.
Another thing I see all the time is that on an unlit road, many people use high beam (and light bars etc) and won't see other vehicles coming around bends etc until they've already blinded them as they round the bend, so it doesn't matter how good your dip beam is!
I run halogens on both my series, and the 88" as my daily driver also has a pair of pencil beam sealed beam halogen Lucas lamps wired in with high beam (obviously all through relays). Part of my reasoning for fitting them was, to be honest, to give me a better chance of being able to see where I am going when meeting oncoming traffic on unlit rural roads. EDIT: funnily enough the headlight units I tend to use are Wipac Quadoptics which are lovely and cheap second hand, but have a great beam pattern and a plastic (non-rusting!) reflector. The amusing thing is they seem to be so cheap as Defender take out units as everyone seems to be fitting, you guessed it, LED units instead
Anyway, besides all this, they look *&%^$ awful
