Great for 3x 12v 4w bike light power source
, August 18, 2012
Bought this generator and three of these:LED MR16 7000K Cool White Spotlight 12V 4W (440 Lumen - 50 Watt Equivalent) 45 Degree Beam angle
Mounted the Generator on the Rear Frame.
Mounted TWO of the 12v 4w LED lights on the Front on the handle bars.
Modified the Rear Reflector and inserted the third 12v 4w LED into it.
Note: The LED lights don't come with any type of mounting hardware.
Use your imagination. Create your own housing or mounting solution for the lights. =)
Note: Marked on the back of the generator are the letters "T" and "H"
H is for Head light, 12v Positive.
T is for Tail light, 3v Positive.
For Ground (-) negative, run a wire from the mounting brackets or the tap screw (none hex) of the generator.
Or you can connect it to your bike frame, but running a direct wire from the generator's mounting brackets or tap screw
is more reliable.
I ran network cable from the generator, along the frame, and to the handle bar of the bike.
(Why? because I had a spare network cable laying around.)
A network cable has 4 pairs of wires.
I connected two pair to the "H" for 12v.
I connected one pair to the "T" for 3v.
The last pair I connected to the screw on the mounting bracket for my ground (-) connection.
With this setup, I still had extra connections available if I want to expand.
Note: These 3 LED lights have peg type terminals, but it does NOT matter where the positive or negative wires connected to.
As long as there is one positive to one terminal and one negative to the other terminal, the LED will come on when power
is generated. No worries about reversing the polarity.
I connected all 3 LED lights in parallel, which allows turning off each light individually if a switch is added to the setup.
All 3 LED lights come on even when riding at low speeds.
While riding at night, the lights provide good visibility in front of the bike.
This setup also makes the bike highly visible by others at night.
I would recommend this product to anyone who likes DIY projects.
