    LED Headlight vs. Stock Halogen Bulb

    Now that short days of winter are soon upon us some of you may wish to upgrade your TW headlights.
    I have experienced a few options from stock halogen bulb to upgraded Hella H4 Halogen, to cheap single sided pylon emitters in cheap LED H4 to finally H4 LEDs featuring three sided pylons with CREE chips on each pylon face.
    Here is example of not much better than stock performance of a cheap LED H4 that I subsequently upgraded. Just my opinion but I was disappointed with LED in the video and feel my subsequent purchase was much superior. Links at bottom of this page should show details of various bulb options.


    Note: Adam’s bike has the stock halogen while my bike, the POV (point of view) , has the inexpensive supposedly 55 watt LED.

    I recently upgraded to LED for my headlight. While I like the amount of light thrown down the road I was bit unimpressed with the pattern thereof. I ended up installing a set of 30 degree floodlights and that was just what I needed for the short days in the Pacific Northwest. Still working on getting them aimed so I can get maximum light down the road without blinding someone coming at me.

    I admit the Hi Beams plus auxilliary lights are too bright, my apologies to Dan and everyone else. Just the low beam is appropriate in a group but on the road I like oncoming traffic to see me.
    I was just that I was enjoying the way the beam illuminates the trees and the trail ahead in broad daylight.
    Back home there is fear of setting small bunny rabbits ablaze so I don’t run ‘em much until we have our first rain. Warning, tall tale detected

    No, it's an H4. LED won't work though because the '87 runs the headlight directly off the stator, which is AC.

    ETA: Low power (35/35 watt) version of the H4. If you upgrade your stator and regulator, you can use the higher power version. Or you can rewire your headlight circuit to the outlet of the reg (for DC) and use a 35 watt LED. Or even do the same and use a 55 watt bulb, but you will be running the battery at a loss unless and until you upgrade the stator.

    Here is just the upgraded H4 headlight on Hi-beam. Provides much better illumination to the sides compared to just the simple H4 LEDs whose Hi and Low beam emitters are just on one single pylon face that points upwards ion the stock reflector. Pointing up the emmited light encounters but a fraction of the OEM reflector face. Largest surface area of the OEM reflector is at 3 and 9 o’clock relative to the bulb. Thus the 120 degree separation of the three sided H4 LED in this video puts out light @ ~ 12, 4 and 8 o’clock relative to the bulb and encounters more of the reflector’s surface area.
