JW Speaker 8700 Evolution 2 just fitted as my single Touring headlight, after noting the truth spoken by others of my high-wattage H4 bulb being incompatible with the cheap (shame on you) Triumph plastic reflector.
Looks good in the garage -- will see what I can tell on the road.
Should you wish to follow suit, alas, the Triumph outer shell has a tabbed slot in which fits a corresponding key tab on the back of the plastic reflector. This key has no analog on the JW Speaker unit, and furthermore, the slot tab of the shell interferes with the JW. The metal is thin enough to bend it up and out of the way, but there is no deterministic substitute to ensure the new light is oriented correctly. The Triumph shell has four spring clips that are easily disengaged to remove the plastic reflector, and easily re-engaged to secure the JW -- these too are not keyed in any way and would allow the JW to be installed in any orientation. JW does have the brand name molded in the glass at the bottom, so I sort of guessed where the middle of that was, and aligned it with the weep hole in the bottom of the shell.
