No description available.


Two schematics for motorcycle auxiliary LED lights. Light will be switched on/off whenever motorcycle ignition is switched on. First schematic assumes that you already have switched source for +12V. Second one is connected directly to battery and is switched on with ignition (spliced to rear light or any other source that is powered with ignition).

Light switch has three positions:
* LED's dimmed
* LED lights off
* LED in full brightness

Regardless of switch position LED's will be powered in full with main beam on.

Materials needed (for second schematics):
* wire splice connector - 2pc
* diode (1W is more than sufficient, we use it just to connect relay) - 1pcs
* bullets or crimp connectors for led lights - 4 pcs male, 4 pcs female
* automotive 5 lead relay - 2 pcs
* switch on-off-on - 1pcs (tumber swich with rubber cover will do)
* disconnect terminals, isolated - 13 pcs, red
* ring of fork terminal - 2pcs
* automotive fuse holder & fuse
* Dimmer, PWM - 1pcs
* wires, 18 gauge (0.82 mm2; diamter 1 mm) for power less than 5A
* wires, 16 gauge for power more than 5A and lengt of wire more than 25 in (60cm)
(get different colors so its easier to build. As minimum you should have at least black and red. ideally there would be: red, black, green, yellow, blue, white)
* roll of electrical tape (black is good)
* heat-shrink tubing

* solder iron
* multimeter or old-school test light (multimeter is preferred)
* wire stripper
* electrical screwdriver
* crimpers
* heat source (for heat-shrink tubin)
* elecrical drill (for securing tumbler to dashboard)
* stanley knife
* cutting pliers
