Old headlight out of production, but you can convert to newer design with some modifications.
I did not go this route. As you can see in my avitar, I have some cheapie $25 fog lights from Wally world installed. I just cut up a piece of flat steet to mount ot the three bolts that the headlight mounted too, and mounted the lights to the steel plate. These lights are 50 or 55 watt, but not as good as the stock headlight, but serve the purpose to get me around in the dark without running over anybody.
