sealed beam headlights
My Harney coach has the sealed beam headlights. The high beam is great but, the low beam is almost worthless. I am thinking about changing them to LED's and was wondering if anyone else has already d...

6054 is but one size of rectangular sealed beam light, and most are 60/55 watt high/low beam.
I plan on getting the Cibie 200MM which are a direct replacement for the 6054 size factor.
Into the Cibies, any H4 bulb will fit, but h4 bulb quality is all over the map. Daniel stern recommended me a 70/65 watt Osram bulb for the Cibies.
The Cibie's are 80$ each though before tax. Much more affordable than the JW speaker 8900 series though which are apparently the best, at this time, drop in replacement for a 6054.
My bulbs were suffering almost 3 volts of drop on the wiring. Now with a 12awg relayed harness the voltage drop is only 0.3v. Light output is not linear with voltage but exponential. So reducing voltage drop to the bulbs makes huge huge differences in light output on Halogen bulbs, but at the cost of reduced bulb lifespan.
The actual wattages on H4 bulbs are not really representative of their output. As voltage increases, so does their amp draw, and some bulbs are rated at 12v and others at 13.2, so direct comparison is not wise. Check out this h4 bulb comparison:
