1 - check the reflectors. They are able to be cleaned but WITH CARE!!!! If they are tarnished its a bit of a lost cause doing much else - the entire headlamp will need to be replaced.
2 - clean the lenses. Its a good thing the headlights can be fully dismantled, but take care while doing it and when reassembling make sure the seals etc are intact or its all for nothing.
3 - fit a real headlight relay. The one in the 940 is not a real useful bit of kit imho. A dual relay (one circuit low beam, the other high beam) mounted near the battery with a main B+ feed taken from the back of the alternator will reduce voltage drop to the headlights by about 0.7 to 1 volt. That doesn't sound a lot, but every volt lost results in about a 15% loss of light efficiency.
4 - Once the headlight relay is in place, your switchgear is safe and you can whack in some high-wattage H4 bulbs. Not sure what the regs are over your way, but I can fit 130/100W H4 bulbs and still be legal. Possums and hedgehogs have no chance.
5 -Correctly align the headlights. There is no excuse for poorly aligned lights that either dazzle oncoming traffic on low beam or light up worm casts in the verge. Its not hard to do yourself, or get your local people to sort it.
6 - Brighter bulbs and correct alignment however do not extend the range of the light. That is a design outcome of the lens. If you need more distance, get some quality spotlights. Again, relay, switch them with high beam, and fit a separate isolation switch so you can turn them off and still have high beam available.
7 - Clean the windscreen.
