How much work is it to run the thicker wires for the headlamps? Obviously the destination is the lamp...where is the origination point?
You don't live in the Seattle area by any chance? I saw a 95 540 the other day that looked like a rolling sunbeam...you could have cooked hotdogs in front of that car.
90 535iM and slowly sorting out lighting issues :)
: Many have gone the higher wattage route with out toasting the headlamp switch or wires BUT by adding a nice set of relays and some 10g and 12g wire you can get 20% more light out of your existing setup. Think what this does for 100w or 120 w bulbs.
: If you are sticking with stock wiring 100w high and 70w lows are a very safe bet. The wiring with relays is fairly easy and intuitive. I solder and heat shrink everything now as I once had a ground connection go bad and could diagnose the problem. Wrap everything in that plastic wire loom stuff and you have a factory looking job.
