Blinking too fast

I have just replaced all four blinkers (turn signals) to LED and all of a sudden they blink too fast, its as though one was out, but there all working,

Probably need to install resistors to pull the load down. LEDs take a lot less power than incandescent bulbs.

The resistance of LEDs is less than regular bulbs causing the blinker to go too fast. The blinker must be changed to be compatible with the LEDs.

I understand what your saying about the load and it makes sense but these LED's are vehicle/model specific???

I've got a few spares that I'll sell you? $12 shipped for 2?
They go between the positive and negative wires.

I'm honestly not sure. I think there are some threads on here about it though. Sorry I'm no more help.

Do you need one for each bulb or just the two?

I'm about to change out all the bulbs on my wife's FX50S, would I have the same problem on that?

Yessir. You only need to use a resistor on the turn signals.

I think I have 4 or like 10 of the exact resistors you need.
PM me, I'll cut you a deal so I can get these things out of my garage (they're brand new btw) or you can text me (31O)eight nine three-42O7

Actually the resistance on LED is too high, hence putting a smaller but high wattage resistor in parallel to get to a smaller value. As suggest it goes between ground and the blinker wire on each blinker LED. If you are unsure about the value, just measure the original bulb and get a similar resistor, but make sure the wattage is high enough. A 4 Ohm resistor at 12V will need an resistor of about 40W, but since it is only 50% on, I would think a 30W might be enough.
