tail.breake.signal.running lights in rear

i have customized my 82 xj750 maxim and put a small round LED in the rear fender for breake and tail light it works fine but i am trying to hook up some new signals in the rear with it. They are dual filament signal lights and i can get them to work but the problem is when the signal is flashing the tail/breake light flickers with the signal lights Dont want this, any help. I have tryed diff hook ups but the way i have it hooked up right now is the only way that looks right to me and works correctly. Rear tail power,brake power,ground. Signal power,running power,ground. In the original set up the signals were not dual filament so hooked up signal running power to power to tail light.

 

Hi ETS,
I hope I'm reading it right but it looks like your saying,
1. Your tail and brake light work fine (although altered to LED type lights).
2. Your indicator lights have been changed to dual filament and your energising both filaments.

If this is the case then maybe your drawing a larger current than the original single filament indicator to energise the new double filament indicator lights and this is affecting the low current electronic LED circuit...

From memory a standard 5V 50mA(so 0.25W which equals W / V = 12V 20mA) is required to power most LEDs 40-80mA is common where as the original specs for the Incandescent is 12V 27w. so... Watts/Volts = Amps ie. 12V 2.25A so if you double that by using a dual filament globe there is whole lot of extra load on the electrical system even though you've reduced the load somewhat with the LED tail light.

This is all a bunch of supposition on my part as I can't say I know anything about dual filament indicators as I haven't seen any specs on any and for all I know they might be half the wattage on each filament anyway.

My suggestion, if any of the above is correct, would be to revert to the single filament indicator globe with the same wiring modifications you've done to remove the dual filament globe(load) from the equation and test your wiring modifications.

FYI: (OHMS Law)

VOLTS
--------------------------
AMPS x RESISTANCE​

so
V / A = R or
V / R = A or
A x R = V
egs: (12Volts / 2.5Amps = 4.8Ohms(Resistance))
(12V / 4.8Ohms = 2.5Amps)
(2.5Amps x 4.8Ohms = 12V)

Algebra! FTW

and

VOLTS x AMPS = WATTS​

I hope this helps...

 

The LEDs are much more sensitive to slight current fluctuations than the incandescent bulbs they replaced. There is probably no easy fix as long as LEDs and incandescent bulbs are mix-n-matched in the same circuit like that. You could try running an independent ground wire for their circuit back to the battery and see if that helps.

 

thanks for the info on the lights i will try the ground to the battery and see and keep trying thanks
