Those sealed beam lights are weak on the output. I've converted at least four sets of driving lights from the sealed beams to the Adjure diamond cut Ice lights. Be sure to get the "diamond cut Ice" version reflector. That reflector has the same design as the Valk OEM headlight which looks kinda nice, but the reflector in the Adjure makes a huge difference. They're not a sealed beam lamp so you can simply replace the bulb instead of the entire lamp, similar to the headlight method. And, using a 35w bulb in the Adjure gives you much more light output than the 35w sealed beam. Get them off the internet at
http://www.powersportparts.net/They're about $20 less a set from there than anywhere else. Another warning, if you want to go to the Adjure website don't just type in Adjure.com....you get a porn site. That was a bit of a surprise when I first went looking. The Adjure site is:
www.Adjureinc.com so be sure to add the "inc" at the end or you get a totally different form of "headlights."
