Hi Al,
I installed the bulb last Fall and have no idea what kind on longevity it will have. The packaging has the CREE LED name on it but cannot confirm it is a genuine CREE product. Additionally, I just bought a Sylvania LED 194 bulb to replace the incandescent pilot bulb and hope to install it soon. I plan on checking the current draw of both headlight & pilot light combined when I get a minute and post my numbers.
I installed an Auxito brand LED in my '87 Lemans, it fit fine whereas, it would not fit the V11 Lemans...base was too thick and overall length was 8-10mm too long as I recall.
4/30/23 Update: The LED bulb described in the pic below draws 0.45 amps on low, 0.65 amps on high. I thought these values were way too low but when I did the math for a 9w bulb (W divided by V = A), it was in the neighbrhood. The originalH4 had a 4.18 amp draw. I wonder how bright this will be at night??!! Glad I'm not out after dark.
7/6/23 Update: The LED bulb described in the pic below has failed, I'm now in pursuit of another.
The Auxito bulb I installed in my '87 Lemans draws 1.7a on low beam, 2.1a on high. I've been out after dark with this bike, I was racing against sunset and sunset won, The Auxito bulb provided me with plenty of light imho.
