    the reason that the 6ohm resistor doesnt work properly is that the LEDs dont draw enough current to discharge the capacitor that is responsible for flashing the turn signals. by adding a resistor in parallel, the resistance is lowered.. increasing the current draw. getting the resistance lower with a 3ohm draws more current through, making the capacitor take longer to fully charge

    Who would of thunk it. I come from the Infantry mindset that if 3 ohm is good, 6 ohm should suffice; mo' better. Thanks for all of the insight and I'll secure some 3 ohm resistors of the same brand so hopefully I can still use one of the pre-drilled mounting holes from the 6 ohms.

    I never knew they used a cap to manage the pluses... of course now that you say it, it makes perfect sense as to why they'd do it that way and why they blink faster with less of a load...

    I guess I figured modern cars would control it digitally..

    ... at least we're no longer using blinker cams.
