Instead of dinking with just the bulb - I opted for a complete lamp replacement.
Found a nice replacement headlight for the LF250/250B. May fit other models:

The whole light assembly was only $39 and takes a standard, easy to find, off the shelf H4 halogen bulb (INCLUDED!)

Wiring even matched up! Blue to blue, white to white, green to green, and leftover yellow to brown.
Couldn't believe the difference in what I could see that night!
Try everything in life once, and the fun things twice!
