Installing led spot lights on my JK

[MISSN2]

Ok guys I'm after a little bit of help I have installed a set if 185w led spotties on my bullbar and a set of duallies on my a pillar when i turn the lights on they work perfectly with the car off I turn the car on and the relay is noisy and looks like the lights are flickering . Does anyone know how to fix this and why it happens or should I take it to an auto elec? Any help and info would be great.

Thanks

You'll have to be more specific as to how you wired them up.

Were did you get your trigger from.

Trigger was from high beams but the issue was incorrect relay and a dodgey led duallie

You need to put an in line capacitor on the trigger line from the high beams to the relay... They are power pulsed to the stock halogens, you don't see flicker, but with led's you will see the flicker due to the pulsing power.

Different relays also react differently to the pulsing. I found there is a Narva relay that is stated has an inbuilt diode - that one worked perfectly on mine with jo additional components required.

I'm no electromatronical engineer... but a diode won't (or at least shouldn't) damp out the pulses. A diode basically is like a 1 way valve, it only lets current flow in 1 direction. It protects from current spikes travelling back to your computer (for example), so many relays have a diode built in for protection.

It may be a co-incidence that the relay is slow acting, so that you don't get the chatter..? Anyway, technically (says the non engineer), a capacitor is the jigger you need to damp out the pulses and keep a constant current on the relay to stop chatter.

Here is a link I saved on how to wire up LED's.... hopefully it still works...
