Bought and installed a Hella European Technology High Performance headlamp in the high beam socket of the 66 300M last night. That headlight would illuminate Idaho from any part of Montana. Part number 71156 looks very much like your standard G.E. bulb but has a beam you could walk on and requires 55 watts each. Year One has them on backorder so they shipped but one now, one later. I'm thinking one might be enough if installed on the right side. They are not certified as meeting any Federal standards and Hella is real emphatic that you should not put them in your street car but for late night drives in rural areas, you've not seen the match for bright. Drop-in match for your standard high beam bulb. Lefty [Non-text portions of this message have been removed]
