I would like to replace the headlamps on my 2001 winnebago Adventurer 37g the low beams are dim can anyone tell me the brightest sealed beam headlamp to purchase? I have heard the Sylvania brand are bright has anyone heard of the GE nighthawks? what part number are the new headlamps mine are GE B21
I've had dim headlights on my Itasca (Winnebago) and discovered that it is a common problem.
I think that you have a couple things going on here:
Some brands of headlights are known to dim with time. I replaced mine with the Sylvania ones.
The Ford headlamp switches of that era have a high failure due to the amount of amps running through it. I've replaced mine twice when they burnt out.
You have a lot of amps going through a long run of 14-guage wires. Not good. Your voltage will drop off to the lights over time. As many have done here, I have re-wired my lights directly to the battery via a relay and heavy guage wiring. This will take most of the load off of the headlamp switch and get a lot more voltage to your lights.

thanks for the response just picked up two sylvania H4666 xtravision headlamps hope they make a difference will check the voltage at the headlamp also. I had a really had a difficult time seeing at night on some two lane curvy roads near Gatlinburg, Tn. Visibility was terrible I am hesitant about driving at night right now.
Measure your voltage at the headlights with the lights on (engine running). Mine was 10.5 volts.
My solution was an HID conversion kit from DDMTuning.com. Lots more light. It uses the old headlight wiring only as a "trigger", so the old wires do not carry much current. Required a separate 20 amp circuit ran to the the lights. I think my cost was about $70.
You'll find a lot of reading and other remedies if you search for dim headlights or some variation of that.
