818 front directional lights

[cob427sc]

I have a Gen 2 818 and I am trying to wire the 4 FFR supplied LED lights for each headlight bucket. There are three lights with 3 wires each (black, yellow and white) and one bulb with just yellow and black wires. There are no directions in the manual as to how these are to be positioned in the headlight housing or how they are to be wired. I wired the 2 wire bulb to the directionals and it flashes yellow only when the headlights are not on, then it just stays constant yellow. I wired the yellow wire in the 3 wire bulbs to the directionals and the white to the parking lights. All blacks to ground. The only bulb that comes on is the 2 wire as noted above and nothing else works. Headlights work fine. What am I missing?

the LEDs with 2 wires is the directional, the 3 (3wire) LEDs are the running lights and are all white. I don’t think it matters if you use the white or the yellow as battery, mine worked the same with either one. As a side note, the white running lights are extremely dim if you don’t have 12v or more. Without the engine running it’s typically 11.##.

Helixx’s advice is spot on. I would only add to be sure to insulate the yellow or white wires you aren’t using.

For the technically curious, I discovered that the white wire powers the LED directly with black grounded. The yellow wire is connected to the white wire through a 100 ohm resistor. Since the LED's impedance is much greater than 100 ohms, the reduction in brightness using only the yellow wire for power is barely perceptible. (To see it, connect the yellow to power, black to ground, and touch the white wire to the yellow.) This arrangement must serve some purpose in at least one of the lamp’s intended uses, but I don’t know what. Perhaps it is used as a current limiter or a current sensor. It certainly doesn’t matter in the 818.

Thanks guys. I'm pretty good (for a civil engineer) on all the mechanical stuff but electri has always been my downfall. As autos become more computer controlled I really feel I'm in the dark ages.
